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>
