Bethlehem Pike is a historic 42.21 mi (67.93 km) long road in the U.S. state of Pennsylvania that connects Philadelphia and Bethlehem, Pennsylvania. It began as a Native American path called the Minsi Trail which developed into a colonial highway called the King's Road in the 1760s. Most of the route later became part of U.S. Route 309, now Pennsylvania Route 309.

Pennsylvania Route 309 is a state highway that runs for 134 miles (216 km) through eastern Pennsylvania. The route runs from an interchange between PA 611 and Cheltenham Avenue on the border of Philadelphia and Cheltenham Township north to an intersection with PA 29 in Bowman Creek, a village in Monroe Township in Wyoming County. The highway connects Philadelphia and its northern suburbs to Allentown and the Lehigh Valley, and Hazleton and Wilkes-Barre in Wyoming Valley.
