'''Interstate&nbsp;83''' ('''I-83''') is an [[Interstate Highway]] located in the states of [[Maryland]] and [[Pennsylvania]] in the [[Eastern United States]]. Its southern terminus is at a signalized intersection with [[Fayette Street]] in [[Baltimore|Baltimore, Maryland]]; its northern terminus is at [[Interstate 81|I-81]] near [[Harrisburg, Pennsylvania]]. I-83 runs from [[Downtown Baltimore]] north to [[Interstate 695 (Maryland)|I-695]] near the northern suburb of [[Timonium, Maryland|Timonium]] on the '''Jones Falls Expressway''' before forming a [[concurrency (road)|concurrency]] with I-695. After splitting from I-695, the route follows the '''Baltimore–Harrisburg Expressway''' north to the border between Maryland and Pennsylvania. Upon crossing the state line, I-83 becomes the '''Veterans of Foreign Wars of the United States Memorial Highway''' and continues north through [[York, Pennsylvania|York]] toward the Harrisburg area. The route runs along the southern and eastern portion of the [[Capital Beltway (Harrisburg)|Capital Beltway]] that encircles Harrisburg before reaching its northern terminus.

Most of the route south of [[Lemoyne, Pennsylvania]], is a direct replacement of [[U.S. Route&nbsp;111]] (US&nbsp;111), a former spur of [[U.S. Route 11|US&nbsp;11]].

===Maryland===
====Jones Falls Expressway====
[[File:83 in Baltimore.jpg|right|thumb|I-83 seen from the US&nbsp;40 (Orleans Street) bridge in Baltimore, Maryland]]
The '''Jones Falls Expressway''' ('''JFX''') is a {{convert|10.2|mi|km|adj=mid|-long}} [[freeway]] that carries I-83 from [[Downtown Baltimore]] to the northern suburbs. It is the area's true north–south artery because [[Interstate 95 in Maryland|I-95]] runs from southwest to northeast through the southern edge of the city. Its southern terminus is at [[Fayette Street]], and its northern terminus is at [[Maryland Route&nbsp;25]] (MD&nbsp;25), just north of the [[Baltimore Beltway]] ([[Interstate 695 (Maryland)|I-695]]). Inside [[Baltimore]], the road is maintained not by the [[Maryland State Highway Administration]] (MDSHA), which controls most freeways in the state, but by the city's [[Baltimore City Department of Transportation|department of transportation]].

The freeway begins at an at-grade, four-way intersection between the JFX, Fayette Street, and [[President Street (Baltimore)|President Street]], located in close proximity to the [[Phoenix Shot Tower]]. President Street continues south along the eastern edge of the [[central business district]] (CBD) to terminate at a traffic circle in [[Inner Harbor East, Baltimore|Inner Harbor East]]. Fayette Street serves as an access route into the downtown area.

Passing beneath the Orleans Street Viaduct ([[U.S. Route 40 in Maryland|US&nbsp;40]]), the JFX runs north, passing near the [[Washington Monument (Baltimore)|Washington Monument]]. Between exits&nbsp;3 and 4, there is a 90-degree turn that sometimes requires motorists to slow down just before entering it, with an advisory speed posted at {{convert|40|mph|km/h|abbr=on}}. The curve is located between the [[Guilford Avenue]] and [[Preston Street (Baltimore)|Preston Street]] overpasses. Within the curve, the southbound JFX interchanges with [[Maryland Route 2|MD&nbsp;2]], with an exit to [[St. Paul Street (Baltimore)|St. Paul Street]] and an entrance from [[Charles Street (Baltimore)|Charles Street]] (MD&nbsp;139).

[[File:2016-07-12 15 30 04 View south along Interstate 83 (Jones Falls Expressway) just south of Exit 10 (Northern Parkway) in Baltimore City, Baltimore.jpg|thumb|left|I-83 southbound on the JFX past Northern Parkway in Baltimore, Maryland]]
Having passed this curve, the JFX begins to parallel [[Maryland Route 25|MD&nbsp;25]], going under the [[Howard Street Bridge]] and interchanging with Maryland Avenue and North Avenue ([[U.S. Route 1 in Maryland|US&nbsp;1]]/[[U.S. Route 40 Truck (Baltimore, Maryland)|US&nbsp;40&nbsp;Truck]]) before continuing north past [[Druid Lake]], forming the northeastern boundary of [[Druid Hill Park]]. Running northwest out of the city center, the JFX is paralleled by its namesake river, the [[Jones Falls]], on one side, and the [[Maryland Transit Administration]]'s [[Baltimore Light RailLink]] line on the other. Closer to downtown, the light rail line peels off in a different direction, while the falls flows directly underneath the elevated freeway.

After interchanging with [[Cold Spring Lane]] and [[Northern Parkway (Baltimore)|Northern Parkway]] (between which lies [[Cylburn Arboretum]]), the JFX exits Baltimore, entering [[Baltimore County, Maryland|Baltimore County]]. Passing close to [[Mt. Washington Pediatric Hospital]], [[Mount Saint Agnes College]], and [[Jones Falls Park]], the route skirts the edge of [[Lake Roland (park)|Lake Roland]] before interchanging with [[Ruxton Road]] just south of [[Interstate 695 (Maryland)|I-695]] (Baltimore Beltway).

At the beltway, I-83 leaves the JFX and joins I-695 for a distance of {{convert|1.4|mi|km}}, where it separates from the latter route to continue onward into northern Maryland. Meanwhile, the JFX continues for another {{convert|0.5|mi|km}} in a four-lane divided format before terminating at an at-grade intersection with MD&nbsp;25 (Falls Road). I-83 and I-695 split off at the southern terminus of the Baltimore–Harrisburg Expressway, and I-695 continues its eastward trek toward [[Towson, Maryland|Towson]] and [[Parkville, Maryland|Parkville]].

====Baltimore–Harrisburg Expressway====
[[File:2019-07-17 12 51 13 View north along Interstate 83 (Baltimore-Harrisburg Expressway) from the overpass for westbound Maryland State Route 943 (West Warren Road) in Cockeysville, Baltimore County, Maryland.jpg|left|thumb|I-83 northbound at Warren Road in Cockeysville, Maryland]]
After separating from the beltway, I-83 is now known as the '''Baltimore–Harrisburg Expressway'''. Running due north away from the beltway, the route parallels [[Maryland Route 45|MD&nbsp;45]] (York Road), the former route of [[U.S. Route 111|US&nbsp;111]]. Passing to the west of [[Timonium, Maryland|Timonium]] and [[Cockeysville, Maryland|Cockeysville]], I-83 leaves the suburban belt around Baltimore and enters rural Baltimore County just north of [[Hunt Valley, Maryland|Hunt Valley]] at [[Shawan Road]]. I-83 and MD&nbsp;45 continue to parallel one another through the northern portion of the county, with MD&nbsp;45 crossing over I-83 once, at an interchange. This segment of I-83 has several sections with higher than usual gradients.

The only major settlement encountered by I-83 along this stretch is [[Monkton, Maryland|Monkton]], reached via [[Maryland Route 137|MD&nbsp;137]]. To the west of I-83, MD&nbsp;137 connects with the northern terminus of MD&nbsp;25, I-83's former companion to the south.

The Interstate eventually crosses the [[Mason–Dixon line]] into [[York County, Pennsylvania]], {{convert|25|mi|km}} north of Baltimore, mere feet from a partial interchange with [[Freeland Road]] and parallel with MD&nbsp;45; the latter route becomes the [[Susquehanna Trail]] when it reaches Pennsylvania.

The route bypasses the boroughs of [[Loganville, Pennsylvania|Loganville]] and [[Jacobus, Pennsylvania|Jacobus]] before entering the city of York.

I-83 has a business route through downtown York, known as [[Interstate 83 Business|I-83 Business]] (I-83 Bus.). The business route follows the former path of US&nbsp;111, while I-83 turns northeast and then north again to bypass the urban area. Near [[Pennsylvania Route&nbsp;462]] (PA&nbsp;462), the [[Lincoln Highway]], the Interstate turns west for a short distance, then north again to an interchange with [[U.S. Route 30 in Pennsylvania|US&nbsp;30]]. Beyond US&nbsp;30, I-83 resumes its straight path, running due north out of York and passing to the west of [[Emigsville, Pennsylvania|Emigsville]].

North of [[Pennsylvania Route 297|PA&nbsp;297]], I-83 is known as the Susquehanna Expressway.{{Citation needed|date=May 2013}} It maintains this name as it passes to the south and west of [[Valley Green, Pennsylvania|Valley Green]], continuing north toward [[Harrisburg, Pennsylvania|Harrisburg]]. South of Harrisburg, I-83 has an interchange with [[Interstate 76 in Pennsylvania|I-76]] ([[Pennsylvania Turnpike]]). North of I-76, I-83 continues due north, passing through [[New Cumberland, Pennsylvania|New Cumberland]], before an interchange with the eastern terminus of [[Pennsylvania Route 581|PA&nbsp;581]] in [[Lemoyne, Pennsylvania|Lemoyne]].

After the interchange with PA&nbsp;581, I-83 is known as the [[Capital Beltway (Harrisburg)|Capital Beltway]]. The highway turns due east and crosses the [[Susquehanna River]] over the [[John Harris Bridge]], south of [[Downtown Harrisburg, Pennsylvania|Downtown Harrisburg]], passing south of [[Paxtang, Pennsylvania|Paxtang]] before encountering [[Interstate 283|I-283]] and [[U.S. Route 322 in Pennsylvania|US&nbsp;322]] at the Eisenhower Interchange. Within the interchange, I-83 exits from itself, with each direction of traffic following a one-lane ramp; facing east, I-83's former lanes become US&nbsp;322, while, facing north, I-283's lanes become I-83. The interchanges includes ramps to local roads as well. From this point northbound to exit&nbsp;51, traffic is often congested during daylight hours. I-83 and westbound US&nbsp;322 continue north toward US&nbsp;22 and I-81, I-283 goes due south toward the turnpike and [[Pennsylvania Route 283|PA&nbsp;283]]'s western terminus, and eastbound US&nbsp;322 goes due east toward [[Hershey, Pennsylvania|Hershey]].

Beyond this interchange, I-83 and US&nbsp;322 run due north through the eastern suburbs of Harrisburg, interchanging with [[U.S. Route 22 in Pennsylvania|US&nbsp;22]] northeast of the CBD in [[Colonial Park, Pennsylvania|Colonial Park]], before I-83 terminates at a three-way semidirectional interchange with [[Interstate 81 in Pennsylvania|I-81]]. From here, US&nbsp;322 continues west along I-81 south.<ref name="Google Maps I-83 PA">{{google maps|url=https://maps.google.com/maps?f=d&source=s_d&saddr=I-83+N&daddr=Exit+51B&hl=en&geocode=FZYYXgId-Fdu-w%3BFegfZwId66tr-w&mra=ls&sll=40.306384,-76.82986&sspn=0.007396,0.01929&ie=UTF8&t=h&z=9|title=Interstate 83 in Pennsylvania|access-date=March 8, 2011}}</ref>

==History==
===Pennsylvania===
[[File:I-83 NB-US 322 WB from Union Deposit Road overpass.jpeg|thumb|right|I-83 northbound/US 322 westbound at Union Deposit Road in Progress, Pennsylvania]]
I-83 was one of the first Interstate Highways built in Pennsylvania. Much of its routing through the state follows a freeway bypass of the since decommissioned [[U.S. Route 111|US&nbsp;111]]. The route received the I-83 designation in 1960. The first section built (opened 1954) runs from [[Pennsylvania Route 392|PA&nbsp;392]] in [[Newberry Township, Pennsylvania|Newberry Township]] north to [[Pennsylvania Route 114|PA&nbsp;114]] in [[Fairview Township, York County, Pennsylvania|Fairview Township]]. The entire highway was completed in 1971 with the massive Eisenhower Interchange in Harrisburg.<ref>{{cite web |last1=Kitsko |first1=Jeffrey J. |title=Veterans of Foreign Wars of the United States Memorial Highway |url=http://www.pahighways.com/interstates/I83.html |url-status=live |archive-url=https://web.archive.org/web/20190206171413/http://www.pahighways.com/interstates/I83.html |archive-date=February 6, 2019 |access-date=January 25, 2019 |website=Pennsylvania Highways}}</ref>

From 2012 to 2015, the I-83/PA&nbsp;581 interchange outside of Harrisburg, Pennsylvania, was modified. Formerly, I-83 was reduced to one lane going northbound through the interchange, resulting in frequent traffic jams during peak travel times. The northbound part of the highway was widened, one bridge was replaced, and several exits in the vicinity were reconfigured.<ref name=i83beltway>{{cite web|title=I-83/PA 581 Interchange Bottleneck Safety Project|url=http://www.i-83beltway.com/ess1/i83pa581.html|work=i83beltway.com|access-date=May 26, 2013|url-status=dead|archive-url=https://web.archive.org/web/20120731043940/http://www.i-83beltway.com/ess1/i83pa581.html|archive-date=July 31, 2012}}</ref> A second project started in 2016, with work to be completed from its northern terminus at I-81 to just past the Union Deposit Road interchange. The project, completed in 2022, reconstructed two interchanges and associated overpasses, as well as widened adjacent sections of the highway to six throughlanes.<ref>{{Cite news |last=Smith |first=Paul |date=May 2, 2016 |title=Bridge Construction along Interstate 83 Corridor to cause Delay |url=https://www.fox43.com/article/news/local/contests/bridge-construction-along-route-83-corridor-to-cause-delay/521-d6b84fc5-d48a-4af8-a68b-85292e3d71a9 |url-status=live |archive-url=https://web.archive.org/web/20161221021328/http://fox43.com/2016/05/02/bridge-construction-along-route-83-corridor-to-cause-delay/ |archive-date=December 21, 2016 |access-date=December 17, 2016 |work=[[WPMT]] |language=en}}</ref><ref>{{cite web|title=I-83 East Shore Section 1|publisher=Pennsylvania Department of Transportation|url=https://www.i-83beltway.com/projects/east-shore-section-1.php|access-date=March 11, 2024}}</ref>

The interchange with [[Pennsylvania Route 851|PA&nbsp;851]] near Shrewsbury was reconstructed into a [[diverging diamond interchange]], which opened to traffic on June 28, 2021.<ref>{{cite news |last=Boeckel |first=Teresa |date=June 28, 2021 |title=New diverging diamond at I-83 Exit 4 has opened, watch for new traffic pattern |url=https://www.ydr.com/story/news/2021/06/21/interstate-83-exit-4-new-diverging-diamond-opening-soon-route-851-closed-weekend/7736438002/ |accessdate=September 29, 2021 |work=[[York Daily Record]] |language=en |archive-date=September 29, 2021 |archive-url=https://web.archive.org/web/20210929194410/https://www.ydr.com/story/news/2021/06/21/interstate-83-exit-4-new-diverging-diamond-opening-soon-route-851-closed-weekend/7736438002/ |url-status=live }}</ref>

In York, Pennsylvania, a reconstruction of the Mt. Rose Avenue ([[Pennsylvania Route 124|PA&nbsp;124]]) interchange took place from 2015 to 2022 in anticipation of a future widening of I-83 around the east and north sides of the city. Also, studies are being done north of town to help ease traffic in a section heavily traveled by trucks.<ref>{{Cite news |last=Boeckel |first=Theresa |date=August 1, 2016 |title=I-83/Mt.

On October 23, 2023, work began on a project that will reconstruct the section of I-83 in Dauphin County, Pennsylvania, from the John Harris Bridge over the Susquehanna River to the Eisenhower Interchange with I-283 and US 322. The project will be split into two contracts, with the project widening and reconstructing I-83 and rebuilding interchanges. As part of this project, a new interchange will be built with [[Pennsylvania Route 230|PA 230]] (Cameron Street) while the 13th Street interchange will be closed. Construction on both contracts is expected to be finished in 2028.<ref>{{cite press release|title=Work to Begin on I-83 Reconstruction Project in Harrisburg Region in Dauphin County|publisher=Pennsylvania Department of Transportation|date=October 19, 2023|url=https://www.penndot.pa.gov/RegionalOffices/district-8/pages/details.aspx?newsid=2240|access-date=March 11, 2024}}</ref>

===Jones Falls Expressway===
The first Interstate to be built in Baltimore was the JFX; the [[Greater Baltimore Committee]] pushed to enact legislation from the [[Baltimore City Council]] in 1955.<ref>{{cite news |date=January 6, 1956 |title=First Birthday Of The Greater Baltimore Committee |newspaper=[[The Baltimore Sun]] |language=en |issn=1930-8965 |oclc=244481759}}</ref> It was the first to be constructed due to community opposition to the other planned freeways within the city.{{citation needed|date= August 2011}} The JFX follows the path of the [[Jones Falls|Jones Falls River]], a natural corridor that divided the city into eastern and western segments. By the early 1960s, the JFX was completed as far as [[Guilford Avenue]], within the city limits. It was completed as far as Pleasant Street in the downtown area by 1983, but the remaining {{convert|4.4|mi|km}} to [[Interstate 95 in Maryland|I-95]] were canceled in September 1982. To compensate for the loss of the remainder of the JFX, the portion in situ was extended to Fayette Street by 1987, and the Jones Falls Boulevard project substantially rebuilt {{Convert|0.75|mi|km}} of President Street, across from the JFX at Fayette Street, to allow the traffic to and from the Interstate to be collected and distributed from the surrounding city streets. By 1990, the project was completed.

Due to community opposition to the other freeway plans being produced by city officials, the JFX was the very first limited-access highway to be completed within the city of Baltimore and remained so for several years. Originally, the JFX was to continue through the Southeast Baltimore neighborhoods of [[Fell's Point, Baltimore|Fell's Point]]<ref>{{cite news |date=December 20, 1970 |title=Fells Point Case |newspaper=[[The Baltimore Sun]] |page=K-4 |language=en |issn=1930-8965 |oclc=244481759 |id={{ProQuest|541176557}}}}</ref> and [[Canton, Baltimore|Canton]] to a junction with the then-planned I-95, but opposition from residents of those neighborhoods successfully blocked that proposal.<ref>{{cite news |date=March 18, 1993 |title=The End of I-83 |newspaper=[[The Baltimore Sun]] |page=A-20 |language=en |issn=1930-8965 |oclc=244481759 |id={{ProQuest|537830627}}}}</ref> As a result, I-83 became the first Maryland road in the [[Interstate Highway System]].<ref name="I83 First" />

====Planning====

As part of the planning for an east–west route through Baltimore, the alignment of the JFX underwent various modifications. Under the original plan for freeways in Baltimore, the 1962 ''Baltimore 10-D Interstate System'', the JFX would have junctioned I-70N (which became I-70 in 1975) and I-95, which were planned to follow an east–west route through the southern edge of the CBD, near the southeastern edge of the CBD. The JFX would end at roughly the same location where it currently does.<ref name="kozel1">{{Cite web |last=Kozel |first=Scott M. |date=October 24, 1998 |title=Baltimore Early Expressway Planning |url=http://www.roadstothefuture.com/Balt_Early_Expwy_Plan.html |url-status=live |archive-url=https://web.archive.org/web/20110101061921/http://www.roadstothefuture.com/Balt_Early_Expwy_Plan.html |archive-date=January 1, 2011 |access-date=February 13, 2007 |website=Roads to the Future}}</ref> As a result of community opposition to other portions of the 10-D System, the 1969 ''Baltimore 3-A Interstate and Boulevard System'' was adopted by the city. In this plan, the JFX would continue south along its present alignment then turn east and pass through the [[Fell's Point, Baltimore|Fell's Point]] neighborhood on a six-lane elevated viaduct, before continuing east along Boston Street to junction I-95 (which was also rerouted to its current alignment) north of the [[Fort McHenry Tunnel]]. In the mid-1970s, this plan was modified due to fears that the viaduct would result in destruction of the Fell's Point area, which contains many historic properties. Under the modification, I-83 would continue south and descend into a six-lane underwater tunnel beneath the [[Inner Harbor]], then turn east under the harbor, pass to the south of Fell's Point, return to the surface in the [[Canton, Baltimore|Canton]] area and continue to I-95.<ref name="kozel2">{{Cite web |last=Kozel |first=Scott M. |date=August 14, 1997 |title=Baltimore City Interstates |url=http://www.roadstothefuture.com/Balt_City_Interstates.html |url-status=live |archive-url=https://web.archive.org/web/20160304001903/http://www.roadstothefuture.com/Balt_City_Interstates.html |archive-date=March 4, 2016 |access-date=February 13, 2007 |website=Roads to the Future}}</ref>

Under this plan, I-83 was expected to act mostly as a northerly spur to and from the CBD and as an easterly spur to and from the CBD; through traffic was expected to be a small proportion of the total amount making use of the route. I-83's terminus at I-95 would have been a full three-way freeway-to-freeway interchange, with a full complement of ramps provided for access to and from [[Boston Street (Baltimore)|Boston]] and [[O'Donnell Street|O'Donnell]] streets.<ref name="kozel4">{{Cite web |url=http://www.roadstothefuture.com/I83-I95-Int.jpg |title=Scale diagram of I-83/I-95 interchange in Baltimore City |access-date=March 8, 2011 |archive-url=https://web.archive.org/web/20110628182234/http://www.roadstothefuture.com/I83-I95-Int.jpg |archive-date=June 28, 2011 |url-status=dead }}</ref> When construction began on I-95 through East Baltimore in the mid-1970s, a short six-lane section was built within the vicinity of the planned I-83 interchange. This was done in anticipation of I-83 connecting the CBD to I-95, the rest of which carries at least eight lanes of traffic throughout the city.

By 1963, the JFX was completed as far south as Guilford Avenue and, by the mid-1970s, was extended to Monument Street. By 1983, the route extended all the way to Pleasant Street, with a dead-end bridge stub indicating plans to continue south along the 3-A alignment to I-95.

In September 1982, however, the segment of the JFX between Pleasant Street and I-95, a distance of {{convert|4.4|mi|km}}, was officially withdrawn from the [[Interstate Highway System]]. Robert Douglas, then the chief of the Interstate Division for Baltimore City (IDBC), stated at the time that the very high financial costs of the I-83 extension (estimated at $609&nbsp;million in the early 1980s [equivalent to ${{Formatprice|{{Inflation|US-GDP|609000000|1979}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}], and likely to reach $1&nbsp;billion [equivalent to ${{Formatprice|{{Inflation|US-GDP|1000000000|1979}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}] with inflation taken into account) led to the cancelation of the segment. As a result, the JFX was truncated at Fayette Street, ending at an at-grade intersection.<ref name="kozel3">{{Cite web |last=Kozel |first=Scott M. |date=June 13, 2003 |title=Baltimore Interstate Highway Cancellation Details |url=https://groups.google.com/g/misc.transport.road/c/X-AgKTL962Y/m/XHT4Z5k-HTYJ?pli=1 |url-status=live |archive-url=https://web.archive.org/web/20121110051641/http://groups.google.com/group/misc.transport.road/msg/361d3e9967f8745c?dmode=source |archive-date=November 10, 2012 |access-date=January 14, 2024 |website=[[Google Groups]]}}</ref>

To make up for the loss of the I-83 segment, the Jones Falls Boulevard project substantially rebuilt approximately {{Convert|0.5|mi|km}} of President Street between I-83 and the downtown area to provide the capacity to absorb traffic to and from the Interstate; the project was completed by 1987. Other roadways in the canceled I-83 corridor also benefited from major reconstruction and rehabilitation.<ref name="kozel3"/> The federal funding planned to be used for the I-83 extension was instead cross-transferred to other highway projects; routes that may have benefited{{Original research inline|date=August 2009}} include [[Interstate 97|I-97]], [[Interstate 195 (Maryland)|I-195]], [[Interstate 370|I-370]], and the upgrade of a portion of the [[John Hanson Highway]] to [[Interstate 595 (Maryland)|I-595]].

As [[United States Congress|Congress]] worked toward reauthorization of the [[Surface Transportation and Uniform Relocation Assistance Act]], the Greater Lynchburg Chamber of Commerce and other groups in Virginia wanted I-83 extended southward to provide bypasses for [[Charlottesville, Virginia|Charlottesville]], [[Lynchburg, Virginia|Lynchburg]], and [[Danville, Virginia|Danville]], and to link those cities to [[Greensboro, North Carolina]]. By June 1991, Robert LaLone, director of programs for the Lynchburg Chamber, admitted that an Interstate was unlikely, but upgrading [[U.S. Route 29|US&nbsp;29]], with bypasses included, is more likely.<ref>{{Cite news |last=Scism |first=Jack |date=June 9, 1991 |title=New Interstates Likely Impossible Dream |work=[[News & Record]] |location=Greensboro, North Carolina |issn=1072-0065 |oclc=25383111}}</ref>

The possibility of extending I-83 (rather than [[Interstate 99|I-99]]) north to [[Rochester, Monroe County, New York|Rochester, New York]], was discussed at the October 2002 I-99 Task Force meeting. Part of the proposed route on [[U.S. Route 11 in Pennsylvania|US&nbsp;11]]/[[U.S. Route 15 in Pennsylvania|US&nbsp;15]], however, has since been rebuilt as a four-lane surface road that does not meet [[Interstate standards]].{{Cn|date=June 2023}} Expensive additional reconstruction, including new interchanges, service roads, and realignments, would be necessary. The farthest north that I-83 could be extended currently would be [[Benvenue, Pennsylvania]], on a bridge over the [[Susquehanna River]], where a recently built freeway section of [[U.S. Route 22 in Pennsylvania|US&nbsp;22]]/[[U.S. Route 322 in Pennsylvania|US&nbsp;322]] (Dauphin Bypass) downgrades to a divided four-lane surface road. Recently, however, the [[Central Susquehanna Valley Thruway]], a {{Convert|10|mi|km|adj=on}} freeway project along the proposed corridor near [[Shamokin Dam, Pennsylvania]], has been approved and is under construction as of 2016,<ref>{{Cite web |url=http://www.csvt.com/news/construction-updates/index.html |title=CSVT, Construction Updates |website=www.csvt.com |access-date=2020-01-12 |archive-url=https://web.archive.org/web/20190108000551/http://csvt.com/news/construction-updates/index.html |archive-date=January 8, 2019 |url-status=dead }}</ref><ref>{{Cite web |last=Dandes |first=Rick |date=October 21, 2019 |title=Central Susquehanna Valley Thruway River Bridge piers complete; work to continue through winter |url=https://www.dailyitem.com/news/central-susquehanna-valley-thruway-river-bridge-piers-complete-work-to/article_67795599-bd70-5fa6-98f4-54c7334263dd.html |url-status=live |archive-url=https://web.archive.org/web/20191022204344/https://www.dailyitem.com/news/central-susquehanna-valley-thruway-river-bridge-piers-complete-work-to/article_67795599-bd70-5fa6-98f4-54c7334263dd.html |archive-date=October 22, 2019 |access-date=January 12, 2020 |website=[[The Daily Item (Sunbury)|The Daily Item]] |language=en}}</ref> with the first section opening in 2022.<ref>{{cite news |last=Dandes |first=Rick |date=July 8, 2022 |title=CSVT bridge opened to traffic in both directions |url=https://www.dailyitem.com/csvt-bridge-opened-to-traffic-in-both-directions/article_c5187132-fe19-11ec-9c0f-7fe312625660.html |access-date=July 8, 2022 |work=[[The Daily Item (Sunbury)|The Daily Item]] |location=Sunbury, Pennsylvania |language=en |archive-date=May 19, 2023 |archive-url=https://web.archive.org/web/20230519020231/https://www.dailyitem.com/csvt-bridge-opened-to-traffic-in-both-directions/article_c5187132-fe19-11ec-9c0f-7fe312625660.html |url-status=live }}</ref>

In 2005, [[Walter Sondheim]], a prominent Baltimore city planner unveiled a proposal to tear down the elevated portion of the JFX that leads into downtown. In the JFX's place, [[President Street (Baltimore)|President Street]] would be extended north to [[Eager Street]], where the elevated section ends. City officials have since offered tentative support for the idea, though it is unlikely that any action will be taken until about 2020, when the current elevated structure will need an overhaul if it is to remain in use. If the downtown JFX were demolished, Baltimore would join [[San Francisco]], [[Boston]], and [[Milwaukee]] to become among the large U.S. cities that have removed some of their downtown elevated freeways. On May 17, 2009, ''[[The Baltimore Sun]]'' revealed a plan by Rummel, Klepper & Kahl LLP, to tear down {{One2a|{{convert|1|mi|km|spell=in}}}} of the JFX to create an urban boulevard that would help connect downtown to the east side of the city and the [[Johns Hopkins Hospital]].<ref name="gunts2009">{{Cite news |last=Gunts |first=Edward |date=May 17, 2009 |title=Baltimore Looks Into Scrapping Mile-long Stretch Of Jfx To Help Revive East Side |url=https://www.baltimoresun.com/2009/05/17/baltimore-looks-into-scrapping-mile-long-stretch-of-jfx-to-help-revive-east-side/ |url-status=live |archive-url=https://web.archive.org/web/20140714153612/http://articles.baltimoresun.com/2009-05-17/business/0905160106_1_elevated-expressway-jones-falls-expressway-east-side |archive-date=July 14, 2014 |access-date=June 14, 2014 |work=[[The Baltimore Sun]] |language=en |issn=1930-8965 |oclc=244481759}}</ref>

[[File:2021-11-04 11 19 27 View north along Interstate 83 Business (South George Street) at Rathton Road and Country Club Drive in York, York County, Pennsylvania.jpg|thumb|left|I-83 Bus. northbound entering York]]
'''Interstate&nbsp;83 Business''' ('''I-83 Bus.''') is a short [[business loop]] in [[York, Pennsylvania]]. It begins at a [[semidirectional T interchange]] with I-83 south of York, continuing north as a [[controlled-access highway|freeway]] for {{convert|2|mi|km|spell=in}} before the freeway ends at a partial interchange with South George Street, with a southbound exit and northbound entrance. The route continues north along George Street through downtown York, intersecting [[Pennsylvania Route 74|PA&nbsp;74]]/[[Pennsylvania Route 462|PA&nbsp;462]] before leaving the city and intersecting [[U.S. Route 30 in Pennsylvania|US&nbsp;30]]. Here, [[Pennsylvania Route 181|PA&nbsp;181]] begins and runs north [[Concurrency (road)|concurrent]] with I-83 Bus. for a short distance before I-83 Bus. ends at an interchange with I-83. PA&nbsp;181 continues north past the northern terminus of I-83 Bus.

From its designation in 1961 until the designation of [[Interstate 376 Business|I-376 Bus.]] in 2009, I-83 Bus. was the only business route of an Interstate Highway in Pennsylvania.
