'''Interstate&nbsp;80''' ('''I-80''') is an east–west transcontinental [[freeway]] that crosses the United States from [[San Francisco, California]], to [[Teaneck, New Jersey]], in the [[New York metropolitan area]]. The highway was designated in 1956 as one of the original routes of the [[Interstate Highway System]]; its final segment was opened in 1986. At a length of {{convert|2,900.76|mi|km}}, it is the second-longest Interstate Highway in the United States, after [[Interstate 90|I-90]]. It runs through many major cities, including [[Oakland, California|Oakland]], [[Sacramento, California|Sacramento]], [[Reno, Nevada|Reno]], [[Salt Lake City]], [[Omaha, Nebraska|Omaha]], [[Des Moines, Iowa|Des Moines]], and [[Toledo, Ohio|Toledo]], and passes within {{convert|10|mi|km}} of [[Chicago]], [[Cleveland]], and [[New York City]].

I-80 is the Interstate Highway that most closely approximates the route of the historic [[Lincoln Highway]], the first road across the United States. The highway roughly traces other historically significant travel routes in the [[Western United States]]: the [[Oregon Trail]] across [[Wyoming]] and [[Nebraska]], the [[California Trail]] across most of [[Nevada]] and [[California]], the first transcontinental [[airmail]] route, and the route of the [[first transcontinental railroad]], except for the vicinity of the [[Great Salt Lake]].

From near Chicago east to near [[Youngstown, Ohio]], I-80 is a [[toll road]], containing most of both the [[Indiana Toll Road]] and the [[Ohio Turnpike]]. I-80 [[concurrency (road)|runs concurrently]] with I-90 from near [[Portage, Indiana]], to [[Elyria, Ohio]]. In [[Pennsylvania]], I-80 is known as the [[Interstate 80 in Pennsylvania|Keystone Shortway]], a non-tolled freeway that crosses rural north-central portions of the state on the way to [[New Jersey]] and New York City.

===California===
{{main|Interstate 80 in California}}
{{see also|San Francisco–Oakland Bay Bridge|Carquinez Bridge|Yolo Causeway}}
I-80 begins at an interchange with [[U.S. Route 101|US Route&nbsp;101]] (US&nbsp;101) in [[San Francisco]] and then crosses the [[San Francisco–Oakland Bay Bridge]] into [[Oakland, California|Oakland]]. It then heads northeast through [[Vallejo, California|Vallejo]], [[Sacramento, California|Sacramento]], and the [[Sierra Nevada]] before crossing into [[Nevada]].

A portion of the route through [[Pinole, California|Pinole]] involved the experimental transplantation of the rare species [[Santa Cruz tarplant]] in the [[Right-of-way (transportation)|right-of-way]].

===Nevada===
{{main|Interstate 80 in Nevada}}
In [[Nevada]], I-80 traverses the northern portion of the state. The freeway serves the [[Reno metropolitan area, Nevada|Reno metropolitan area]], and it also goes through the towns of [[Fernley, Nevada|Fernley]], [[Lovelock, Nevada|Lovelock]], [[Winnemucca, Nevada|Winnemucca]], [[Battle Mountain, Nevada|Battle Mountain]], [[Elko, Nevada|Elko]], [[Wells, Nevada|Wells]], and [[West Wendover, Nevada|West Wendover]] on its way through the state.

The Nevada portion of I-80 follows the paths of the [[Truckee River|Truckee]] and [[Humboldt River|Humboldt]] rivers, which have been used as a transportation corridor since the [[California Gold Rush]] of the 1840s. The Interstate also follows the historical routes of the [[California Trail]], [[first transcontinental railroad]], and [[Feather River Route]] throughout portions of the state. I-80 in Nevada closely follows, and at many points directly overlaps, the original route of the [[Victory Highway]], [[Nevada State Route 1|State Route&nbsp;1]] (SR&nbsp;1), and [[U.S. Route 40|US&nbsp;40]].

===Utah===
{{main|Interstate 80 in Utah}}
After crossing [[Utah]]'s western border in [[Wendover, Utah|Wendover]], I-80 crosses the desolate [[Bonneville Salt Flats]] west of the [[Great Salt Lake]]. The longest stretch between exits on an Interstate Highway is located between Wendover and [[Knolls, Utah|Knolls]], with {{convert|37.4|mi|km}} between those exits.<ref>{{cite news|last1=Carey|first1=Anne|title=Top 16 longest gaps between Interstate exits|url=http://content.usatoday.com/communities/driveon/post/2011/08/longest-distances-between-exits-on-US-freeways-415029/1|access-date=January 17, 2017|work=[[USA Today]]|date=August 15, 2011|archive-date=June 30, 2017|archive-url=https://web.archive.org/web/20170630190754/http://content.usatoday.com/communities/driveon/post/2011/08/longest-distances-between-exits-on-US-freeways-415029/1|url-status=live}}</ref> This portion of I-80, crossing the [[Great Salt Lake Desert]], is extremely flat and straight, dotted with large warning signs about [[driver fatigue]] and drowsiness.

East of the salt flats, I-80 passes the southern edge of Great Salt Lake and continues on through [[Salt Lake City]], where it merges with [[Interstate 15|I-15]] for {{convert|3|mi|km|0|spell=in}} before entering the [[Wasatch Range]] east of the city. It ascends [[Parleys Canyon]] and passes within a few miles of [[Park City, Utah|Park City]] as it follows a route through the mountains toward the junction with the eastern terminus of the western section of [[Interstate 84 (Oregon–Utah)|I-84]]. From the junction it continues up Echo Canyon and on toward the border with [[Wyoming]], near [[Evanston, Wyoming|Evanston]].

The route of the Utah section of I-80 is defined in Utah Code Annotated §&nbsp;72-4-113(10).<ref>{{cite web|url=http://le.utah.gov/code/TITLE72/htm/72_04_011300.htm |author=Utah State Legislature |title=§&nbsp;72-4-113(10) |work=Utah Code Annotated |access-date=January 29, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20140227042610/http://le.utah.gov/code/TITLE72/htm/72_04_011300.htm |archive-date=February 27, 2014 |df=mdy }}</ref>

===Wyoming===
{{main|Interstate 80 in Wyoming}}
In [[Wyoming]], I-80 reaches its maximum elevation of {{convert|8640|ft|m}} above [[sea level]]<ref name=map>{{cite map |author = Wyoming Department of Transportation |author-link = Wyoming Department of Transportation |year = 2010 |title = Official State Highway Map of Wyoming |scale = c. 1:1,140,480 |location = Cheyenne |publisher = Wyoming Department of Transportation |sections = G1–H10 }}</ref> at [[Sherman Summit]], near [[Buford, Wyoming|Buford]], which, at {{Convert|8000|ft|m}}, is the highest community on I-80. Farther west in Wyoming, the Interstate passes through the dry [[Red Desert (Wyoming)|Red Desert]] and over the [[Continental Divide]]. In a way, the highway crosses the Divide twice, since two ridges of the [[Rocky Mountains]] split in Wyoming, forming the [[endorheic basin|endorheic]] [[Great Divide Basin]], from which surface water cannot drain but can only evaporate.

===Nebraska===
{{main|Interstate 80 in Nebraska}}
I-80 enters [[Nebraska]] west of [[Bushnell, Nebraska|Bushnell]]. The western portion of I-80 in Nebraska runs very close to the state of [[Colorado]], without entering the state. The intersection of [[Interstate 76 (Colorado–Nebraska)|I-76]] and I-80 is visible from the Colorado–Nebraska state line. From its intersection with I-76 to [[Grand Island, Nebraska|Grand Island]], I-80 lies in the valley of the [[South Platte River]] and the [[Platte River]].

The longest straight stretch of Interstate anywhere in the Interstate Highway System is the approximately {{convert|72|mi|km}} of I-80 occurring between exit&nbsp;318 in the Grand Island area and milemarker&nbsp;390 near [[Lincoln, Nebraska|Lincoln]]. Along this length, the road does not vary from an ideally straight line by more than a few yards. After Lincoln, I-80 turns northeast toward [[Omaha, Nebraska|Omaha]]. It then crosses the [[Missouri River]] in Omaha to enter the state of [[Iowa]]. Part of I-80 in Nebraska is marked as a [[Blue Star Memorial Highway]].

===Iowa===
{{main|Interstate 80 in Iowa}}
I-80 is the longest Interstate Highway in [[Iowa]]. It extends from west to east across the central portion of the state through the population centers of [[Council Bluffs, Iowa|Council Bluffs]], Des Moines, and the [[Quad Cities]].<ref name=GoogleIA>{{Google maps|url=https://maps.google.com/maps?saddr=I-80+E&daddr=I-80+E&hl=en&ll=41.722131,-93.284912&spn=5.091524,7.459717&sll=41.577572,-90.369587&sspn=0.083853,0.136471&geocode=Fd4kdQId4IRI-g%3BFfxzegIdyCSd-g&t=h&gl=us&mra=mift&mrsp=1&sz=13&z=7 |title= Interstate 80 in Iowa |access-date=August 9, 2012}}</ref> It enters the state at the Missouri River in Council Bluffs and heads east through the [[southern Iowa drift plain]]. In the [[Des Moines metropolitan area]], I-80 meets up with [[Interstate 35|I-35]] and the two routes bypass [[Downtown Des Moines]] together while [[Interstate 235 (Iowa)|I-235]] proceeds straight through the metro and rejoins both on the far side. In [[Ankeny, Iowa|Ankeny]], the Interstates split and I-80 continues east. On the west edge of the [[Iowa City metropolitan area]], it intersects [[Interstate 380 (Iowa)|I-380]], a segment of the [[Avenue of the Saints]]. Northwest of the Quad Cities in Walcott is [[Iowa&nbsp;80]], the world's largest truckstop. I-80 passes along the northern edge of [[Davenport, Iowa|Davenport]] and [[Bettendorf, Iowa|Bettendorf]] and leaves Iowa via the [[Fred Schwengel Memorial Bridge]] over the [[Mississippi River]] into Illinois. The majority of the highway runs through farmland,<ref name="GoogleIA" /> yet roughly a third of Iowa's population live along the I-80 corridor.<ref>{{cite news |url = http://www.carrollspaper.com/main.asp?SectionID=1&ArticleID=9965 |title = Population grows in I-80, U.S. 30 corridors |last = Staff |date = March 29, 2010 |work = Daily Times Herald |access-date = August 12, 2012 |location = Carroll, IA |archive-url = https://web.archive.org/web/20120915164308/http://carrollspaper.com/main.asp?SectionID=1 |archive-date = September 15, 2012 |url-status = dead }}</ref>

===Illinois===
{{main|Interstate 80 in Illinois}}
{{see also|Tri-State Tollway|Kingery Expressway}}
In [[Illinois]], I-80 runs from the Fred Schwengel Memorial Bridge across the Mississippi River south to an intersection with [[Interstate 74|I-74]]. It then runs east across north-central Illinois just north of the [[Illinois River]] to [[Joliet, Illinois|Joliet]]. I-80 continues east through the [[Chicago Southland|southern suburbs]] of [[Chicago]] and joins [[Interstate 94|I-94]] just before entering Indiana.

===Indiana===
{{main|Borman Expressway|Indiana Toll Road}}
In [[Indiana]], I-80 runs concurrently with another Interstate Highway for its entire length. It runs with I-94 on the [[Borman Expressway]] from the Illinois state line to [[Lake Station, Indiana]], then with [[Interstate 90|I-90]] on the [[Indiana Toll Road]] from Lake Station to the Ohio state line.

Between [[La Porte, Indiana|La Porte]] and the [[Toledo metropolitan area]], I-80/I-90 is located within {{convert|10|mi|km}} of the [[Michigan]] state line but does not enter that state. From the [[Indiana State Road 9|State Road&nbsp;9]] (SR&nbsp;9) and I-80/I-90 interchange, the sign marking the Indiana–Michigan state line is visible. I-80/I-90 passes through the [[South Bend–Mishawaka metropolitan area]], passing the [[University of Notre Dame]] and the [[University Park Mall]], intersecting with the [[St. Joseph Valley Parkway]]. At another point in northern Indiana, I-80/I-90 comes within about {{Convert|200|yd|m}} of the Michigan border.<ref>{{Cite web|url=https://www.microsoft.com/en-us/research/|archive-url=https://web.archive.org/web/20120917161113/http://msrmaps.com/image.aspx?S=12&T=2&X=810&Y=5780&Z=16&W=2|url-status=dead|title=Microsoft Research – Emerging Technology, Computer, and Software Research|archive-date=September 17, 2012|website=Microsoft Research|access-date=June 6, 2020}}</ref>

===Ohio===
{{main|Interstate 80 in Ohio|Ohio Turnpike}}
In [[Ohio]], I-80/I-90 enters from the Indiana Toll Road and immediately becomes the Ohio Turnpike. The two Interstates cross rural northwest Ohio and run just south of the [[Toledo metropolitan area]]. In [[Rossford, Ohio|Rossford]], the turnpike intersects [[Interstate 75|I-75]] in an area known as the Crossroads of America. This intersection is one of the largest intersections of three Interstate Highways in the United States.{{citation needed|date=August 2016}}

In [[Elyria Township, Lorain County, Ohio|Elyria Township]], just west of [[Cleveland]], I-90 splits from I-80, leaving the turnpike and running northeast as a freeway. I-80 runs east-southeast through the southern suburbs of Cleveland. Just northwest of [[Youngstown, Ohio|Youngstown]], the Ohio Turnpike continues southeast as [[Interstate 76 (Ohio–New Jersey)|I-76]], while I-80 exits the turnpike and runs east to the north of Youngstown, entering Pennsylvania south of [[Sharon, Pennsylvania]].

===Pennsylvania===
{{main|Interstate 80 in Pennsylvania}}
In [[Pennsylvania]], I-80 is the main east–west freeway through the central part of the state. It runs from the Ohio state line near Sharon to the [[Delaware Water Gap Toll Bridge]] over the [[Delaware River]] and is called the "Z.H. Confair Memorial Highway".

It traverses the extreme northern section of [[Greater Pittsburgh]]. I-80 serves as the western terminus for [[Interstate 376|I-376]] which connects it to [[Pittsburgh International Airport]] and on to [[Downtown Pittsburgh]] and suburban Pittsburgh. I-80 intersects [[Interstate 79|I-79]], which connects with [[Erie, Pennsylvania|Erie]] (about {{convert|75|mi|km}} to the north) and Pittsburgh (about {{convert|55|mi|km}} to the south). Further east, [[Interstate 99|I-99]] connects with [[State College, Pennsylvania|State College]] and [[Altoona, Pennsylvania|Altoona]]. A spur from I-80 ([[Interstate 180 (Pennsylvania)|I-180]]) runs to [[Williamsport, Pennsylvania|Williamsport]]. Upon entering the [[Pocono Mountains]] region, I-80 meets [[Interstate 81|I-81]], connecting [[Syracuse, New York]], and [[Harrisburg, Pennsylvania|Harrisburg]], and [[Interstate 476|I-476]] which connects with [[Scranton, Pennsylvania|Scranton]], [[Wilkes-Barre, Pennsylvania|Wilkes-Barre]], [[Allentown, Pennsylvania|Allentown]], and [[Philadelphia]]. Another spur ([[Interstate 380 (Pennsylvania)|I-380]]) runs to Scranton.

In [[Clearfield County, Pennsylvania|Clearfield County]], I-80 reaches its highest elevation east of the Mississippi River, {{convert|2250|ft|m}}, although other Interstate Highways east of the Mississippi, including [[Interstate 26|I-26]] in North Carolina and Tennessee, reach higher elevations.

In 2007, the [[Pennsylvania Turnpike Commission]] (PTC), combined with state legislature Act No. 44, initiated plans to enact a tolling system on the entire span of I-80 throughout the commonwealth of Pennsylvania. On October 15, 2007, the [[Pennsylvania Department of Transportation]] (PennDOT) and the PTC signed a 50-year lease agreement, which would allow the PTC to maintain and, eventually, toll I-80.<ref name=Inquirer>{{cite web |last = Nussbaum |first = Paul |title = I-80 toll plans moving forward |work = [[The Philadelphia Inquirer]] |date = October 17, 2007 |url = http://www.philly.com/philly/news/homepage/10595797.html }}{{dead link|date=June 2016|bot=medic}}{{cbignore|bot=medic}}</ref> However, the application for a toll was rejected by the [[Federal Highway Administration]] (FHWA).<ref>{{cite press release |author = Federal Highway Administration Public Affairs |url = https://www.fhwa.dot.gov/pressroom/fhwa1006.cfm |title = Federal Highway Administration Declines Pennsylvania Request to Toll I-80 |date = April 6, 2010 |publisher = Federal Highway Administration |access-date = October 4, 2014 |archive-date = October 6, 2014 |archive-url = https://web.archive.org/web/20141006141511/http://www.fhwa.dot.gov/pressroom/fhwa1006.cfm |url-status = live }}</ref>

===New Jersey===
{{main|Interstate 80 in New Jersey}}

I-80 does not enter [[New York City]]. Once the [[Interstate 95|I-95]]/[[New Jersey Turnpike]] was extended in 1971 from its former terminus at [[U.S. Route 46|US&nbsp;46]] in [[Ridgefield, New Jersey|Ridgefield]] to I-80 in [[Teaneck, New Jersey|Teaneck]], the section from Teaneck to Fort Lee was resigned as I-95, and it is the latter roadway that enters New York City via the [[George Washington Bridge]]. I-80's designated end (as per signage and [[New Jersey Department of Transportation]] (NJDOT) documents) is {{convert|4|mi|km|spell=in}}<ref name="measurement">Measured in Google Earth from I-80 end sign (visible in Street View) to the beginning of the George Washington Bridge</ref> short of New York City in Teaneck, before the Degraw Avenue overpass. There, signs designate the end of I-80 and the beginning of I-95/New Jersey Turnpike northbound.

One section of I-80 running from [[Netcong, New Jersey|Netcong]] to [[Denville, New Jersey|Denville]] was constructed in 1958.

==History==
I-80 was included in the original plan for the [[Interstate Highway System]] as approved in 1956. The highway was built in segments, with the final piece of I-80 completed in 1986 on the western edge of [[Salt Lake City]]. This piece was coincidentally dedicated close to the 30th birthday of the Interstate Highway System, which was noted at the dedication and considered to be a milestone in the history of highway construction in the United States.<ref name=highwayhistory>{{cite journal |first = Richard |last = Weingroff |date = Fall 1986 |url = https://www.fhwa.dot.gov/infrastructure/30thannv.cfm |journal = U.S. Highways |title = America Celebrates 30th Anniversary of the Interstate System |publisher = Federal Highway Administration |access-date = December 28, 2013 |archive-date = October 24, 2011 |archive-url = https://web.archive.org/web/20111024114212/https://www.fhwa.dot.gov/infrastructure/30thannv.cfm |url-status = live }}</ref> It was also noted at the dedication that this was only {{convert|50|mi|km}} south of [[Promontory Summit]], where another first in a transcontinental artery was completed—the [[golden spike]] of the US's [[first transcontinental railroad]].<ref name=nytimes>{{cite news |url = https://www.nytimes.com/1986/08/25/us/around-the-nation-transcontinental-road-completed-in-utah.html |title = Around the Nation: Transcontinental Road Completed in Utah |newspaper = [[The New York Times]] |agency = [[Associated Press]] |date = August 25, 1986 |oclc = 1645522 |access-date = May 13, 2013 |archive-date = March 16, 2017 |archive-url = https://web.archive.org/web/20170316115134/http://www.nytimes.com/1986/08/25/us/around-the-nation-transcontinental-road-completed-in-utah.html |url-status = live }}</ref>

===Geological study===
[[John McPhee]] described the geology revealed by the building of I-80 in a series of books on the formation of the continent of [[North America]], books that were published between 1981 and 1993 and collected in a one-volume edition in 1998 ''[[Annals of the Former World]]'' which won a [[Pulitzer Prize]] in 1999. In "Basin and Range" (1981), he described how the idea emerged in a conversation with Princeton geologist [[Kenneth S. Deffeyes]]:<ref>{{cite book |first = John |last = McPhee |title = Annals of the Former World |location = New York |publisher = Farrar, Straus and Giroux |year = 2000 |pages =  36–37 }}</ref><blockquote>What about Interstate 80, I asked him. It goes the distance. How would it be? "Absorbing," he said. And he mused aloud: After 80 crosses the Border Fault, it pussyfoots along on morainal till that levelled up the fingers of the foldbelt hills. It does a similar dance with glacial debris in parts of Pennsylvania. It needs no assistance on the craton. It climbs a ramp to the Rockies and a fault-block staircase up the front of the Sierra. It is geologically shrewd. It was the route of animal migrations, and of human history that followed. It avoids melodrama, avoids the Grand Canyons, the Jackson Holes, the geologic operas of the country, but it would surely be a sound experience of the big picture, of the history, the construction, the components of the continent.</blockquote>
