Interstate 76 (Pennsylvania Turnpike)

Philadelphia, PA to the Ohio Border

I-76 in Pennsylvania, known as the Pennsylvania Turnpike, runs approximately 359 miles from the I-95 interchange near Philadelphia west through the Appalachians to the Ohio border. As one of the busiest truck toll roads in the United States, it is the primary freight backbone of Pennsylvania. The route crosses multiple Appalachian ridges with grades that have caused runaway truck incidents, winter ice forms rapidly on mountain sections, and high truck traffic density combined with tight curves on the older alignment creates serious accident risk.
