How long is the route that connects Philadelphia to Lehigh County?
Pennsylvania Route 309 Pennsylvania Route 309 (PA 309) is a major highway which runs for 134 miles (216 km) through Pennsylvania in the United States. The route runs from the 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, Wyoming County. It connects Philadelphia and its northern suburbs to Allentown, Hazleton, and Wilkes-Barre. A limited-access highway portion of PA 309 in the Wilkes-Barre area is known as the North Cross Valley Expressway. A limited-access highway portion of PA 309 in Montgomery County is known as the Fort Washington Expressway. PA 309 parallels the newer Interstates 476 and 81 for much of its length.
Nescopeck Mountain Nescopeck Mountain (also known as Nescopec Mountain) is a ridge in Columbia County and Luzerne County, in Pennsylvania, in the United States. Its elevation is 1594 ft above sea level. The ridge is a forested ridge, with at least two types of forest and two systems of vernal pools. It is a very long and unbroken ridge with two water gaps: one carved by Catawissa Creek and one carved by Nescopeck Creek. This later gap was exploited as a transportation corridor with the construction of the Lehigh & Susquehanna Turnpike between the respective frontier communities at Lausanne Landing and Nescopeck (opposite bank from Shickshinny, PA on the Susquehanna River) in 1805 connecting the newly developing Wyoming Valley with Philadelphia and the Delaware River valley; cutting off over 100 miles between Philadelphia and Wilkes-Barre. Today's Route PA 93 derives from this historic pack mule road.
