In April 1963, the state of Pennsylvania proposed renumbering I-80S to I-76 and I-280 to I-276 because the spurs of I-80S did not connect to I-80 in northern Pennsylvania. The renumbering was approved by the [[Federal Highway Administration]] (FHWA) on February 26, 1964. With this renumbering, the turnpike would carry I-80S between the Ohio state line and Pittsburgh, I-76 between Pittsburgh and King of Prussia, I-70 between New Stanton and Breezewood, and I-276 between King of Prussia and Bristol.

In 1971, the state of Ohio made plans to eliminate I-80S, replacing it with a realigned I-76. The state of Pennsylvania disagreed with the change and recommended that I-80S become I-376 instead. The Pennsylvania government later changed its mind and supported Ohio's plan to renumber I-80S as I-76. In December of that year, the change was approved by the [[American Association of State Highway Officials]].

It involves the addition of variable message signs, a traffic flow system , a truck rollover system, and an overweight vehicle detection system, as well as the installation of cameras at various interchanges.<ref name="Pa Highways"/>

In early 1999, the PTC began printing coupons on the back of toll receipts, primarily for use by business owners.<ref name="Pa Highways"/>

In May 1998, the PTC began to redeck the Delaware River Bridge. As part of this, shoulders and a median barrier were added, though two vehicular lanes would be removed. The Delaware River Toll Plaza was also expanded with added capacity. The project was completed in August 2000.<ref>{{cite web|url=http://www.phillyroads.com/crossings/delaware-toll/|title=Delaware River–Turnpike Toll Bridge|access-date=8 June 2024}}</ref>

Construction began in 1998 to improve the bridge over the Schuylkill River in Montgomery County. The work involved building a new bridge adjacent to the existing bridge; the new bridge was wide enough to accommodate a future widening to six lanes.

On July 12, 2001, reconstruction began on the section between mileposts 109 and 122. Work involved replacing the roadbed and seventeen overpasses (including the Somerset Interchange) to accommodate expanded shoulders and median. On March 21, 2002, a $66 million project to rebuild the roadway from mileposts 85 to 94 began. The project involved reconstructing the Donegal Interchange, and rehabilitating seven other overpasses. An eastbound truck lane was added between mileposts 88 to 94, and westbound truck lane was added between mileposts 93.1 and 92.2. They also built an entirely new roadway east of the Donegal Interchange, replacing a curved section with a straight roadway. While work on the milepost 109-122 project was scheduled to be completed in Spring 2005 and the milepost 85-94 work planned to be competed in November 2005, a fare increase allowed for the both projects to be completed by November 2004.<ref name="Pa Highways"/>

On September 26, 2012, the PTC began a “dry-run” of replacement Automatic Ticket Issuing Machines (ATIM) at the Willow Run Interchange and Lebanon Lanchester Interchange. The new tickets were 1.75 inches longer, printed on thermal paper, and lacked the magnetic strips the old tickets had. In addition, the tickets were not preprinted, meaning that more ink was saved in comparison to the old system. After this test was completed, starting on October 1, the new machines were installed at the low volume interchanges, and by December 6, the high volume interchanges had also transitioned to the new system. This was done because the old 1987 ATIM’shad became obsolete, and if left in use past 2012, they would have became impossible to maintain.<ref name="Pa Highways"/>

In 2012, the PTC began preliminary design on a project to widen the section of roadway between mileposts 57 and 67 to six lanes. This was completed in 2016. Construction then began on a replacement of the Trafton Road overpass, which was completed in 2019. Demolition of the Harviston Road overpass began in August 2024. Unlike the Trafton Road overpass, it is not being replaced due to engineering constraints. Its demolition is currently set for competition in late 2025. Work on the widening itself is not expected to begin until 2032 between mileposts 61 and 67, with the section between mileposts 57 and 61 being determined by its completion. Estimates of its final cost are currently at over $400,000,000.<ref>{{Cite Web|title=Milepost 57-67 Design|url=https://www.paturnpike.com/traveling/construction/site/milepost-57-67-design|date=}}</ref>
