Numbered as a bypass of Philadelphia for I-76, Interstate 276 follows the Pennsylvania Turrnpike mainline 30.0 miles east from the Valley Forge Interchange (Exit 326) to I-95 at Levittown. The toll road serves both through traffic and commuters, with 2017 traffic counts recorded by PennDOT topping out at 122,000 vehicles per day between the Norristown and Mid County Interchanges.
Interstate 276 Highway Guides
The speed limit along all of the Pennsylvania Turnpike mainline was increased from 65 to 70 miles per hour on May 3, 2016.1 Completion of the ramps joining Interstate 95 with the Pennsylvania Turnpike in Bucks County coincided with the renumbering of I-276 east to the Delaware River Turnpike Toll Bridge as the realignment of I-95. The flyovers joining I-95 with the PA Turnpike opened to traffic on September 23, 2018. 2.6 miles of I-276 were subsequently truncated.
The Pennsylvania Turnpike Commission (PTC) converted the entire east-west mainline to all electronic tolling (AET) in Fall 2021.2 Remaining toll booths along the Turnpike will be removed starting in late 2024 with completion in 2025.
