History

Starting out as a Native American path now referred to as the "Minsi Trail", this route became part of the Bethlehem Pike. In 1926, the U.S. Route 309 designation was given to a route that consisted of Stenton Avenue in Philadelphia, Bethlehem Pike (Old Route 309) from the Philadelphia line to Spring House, modern-day PA 309 into Bucks County, Bethlehem Pike (Old Route 309) through Sellersville, modern-day PA 309 from Quakertown to Lanark, and modern-day PA 145 to Allentown; various city streets through Allentown, exiting northward on Walbert Avenue; modern-day PA 309 from Walbert (in South Whitehall Township) to Schnecksville, modern-day PA 873 to Weiders Crossing near Lehigh Gap, modern-day PA 248 to Weissport, modern-day US 209 to Nesquehoning, modern-day PA 93 to Hazleton, and modern-day PA 309 (and PA 309 Business) to Wilkes-Barre.

In 1930 the highway was extended to the New York state line, following River Street to Pittston, modern-day PA 92 to Tunkhannock, modern-day US 6 to Towanda, and modern-day US 220 to South Waverly. In 1946 the route between Wilkes-Barre and Tunkhannock was changed to the modern-day PA 309 alignment from Wilkes-Barre to Bowman Creek and modern-day PA 29 to Tunkhannock.

In 1948, US 309 was dedicated as the Joseph W. Hunter Highway in honor of the first highway commissioner in Pennsylvania.^[2]

In 1954 the routing between Allentown and Hazleton was completely changed. US 309 was routed north on modern-day PA 145 to Fullerton, then west on the Lehigh Valley Thruway along with the rerouted US 22 to Fogelsville. US 309 then turned north on modern-day PA 100 up to Pleasant Corners, and then followed modern-day PA 309 to Hazleton.

Northbound PA 309 approaching interchange with PA 563 in West Rockhill Township

The late 1950s saw the beginnings of bypasses on the route. North of Philadelphia, the Fort Washington Expressway from the PA 73 interchange to north of Spring House opened in 1959; the rest of that expressway from PA 73 south to PA 152 opened in 1961. A bypass west of Allentown from Lanark to US 22 north of Cetronia was completed in 1959, and extended to Walbert in 1962 when US 309 was placed on modern-day PA 309 from US 22 to Pleasant Corners. US 309 had now completely replaced the stretch of the 1920s-era Pennsylvania Route 22 between the former PA 3 in Allentown and the former PA 19 in Wilkes-Barre.

The north end of US 309 between Tunkhannock and Waverly, New York had always been shared with other U.S. highways (6 and 220). In 1964 the US 309 designation was removed from those shared sections, leaving the northern terminus at Tunkhannock. As a result of this, the route was entirely located in Pennsylvania and no longer met the U.S. Highway standards set forth by the American Association of State Highway Officials (AASHO), which discourages routes within a single state.^[2] On October 14, 1967, AASHO approved the elimination of the US 309 designation.^[12] US 309 was decommissioned in February 1968 and was replaced by PA 309. Signs were changed by the end of the month. In 1967, work began on an expressway for US 309 to bypass Sellersville from just north of the Montgomery/Bucks County line to just south of Quakertown. This bypass opened in 1969 as part of PA 309.^[2]
