PA 309 heads north from Philadelphia and becomes a freeway called Fort Washington Expressway through suburban areas in Montgomery County, passing through Fort Washington, before becoming a surface road called Bethlehem Pike and running through Montgomeryville. In Bucks County, the route has a freeway section bypassing Sellersville before passing through Quakertown as a surface road. PA 309 then enters the Lehigh Valley, where it joins Interstate 78 (I-78) on a freeway bypassing Allentown to the south before splitting to the north and running through rural areas as a surface road. The route continues north into the Coal Region, passing through Tamaqua before it reaches Hazleton. PA 309 heads into Wyoming Valley and passes through the Wilkes-Barre area on a freeway alignment along I-81 and the North Cross Valley Expressway before turning into a surface road again, where it runs through Dallas before reaching its northern terminus.

The surface road sections of the route between Philadelphia and the Lehigh Valley follow a turnpike called Bethlehem Pike that was built in the 1800s. With the creation of the U.S. Highway System in 1926, U.S. Route 309 (US 309) was designated to run from US 120 (later renamed US 422) in the Chestnut Hill section of Philadelphia north to US 11 in Wilkes-Barre. When first designated, US 309 followed the present corridor of PA 309 to Allentown before heading further east through Slatington, Palmerton, Lehighton, Jim Thorpe, and Nesquehoning and then following present-day PA 309 between Hazleton and Wilkes-Barre. In 1930, US 309 was extended north to New York State Route 17 (NY 17) in Waverly, New York, heading north to Pittston and Tunkhannock before following US 6 between Tunkhannock and Towanda and US 220 between Towanda and Waverly. By 1940, US 309 was extended south to US 1 Bypass (US 1 Byp.)/US 13 Byp./US 422 at Ridge Avenue and City Line Avenue in Philadelphia.

In the 1940s, US 309 was realigned between Ashley and Tunkhannock to Wilkes-Barre, Dallas, and Bowman Creek, with the former alignment between Wilkes-Barre and Pittston becoming unnumbered and the portion between West Pittston and Tunkhannock designated as part of PA 92. In the 1950s, US 309 was rerouted between Allentown and Hazleton to follow US 22 west to Fogelsville before turning north to Pleasant Corners and following present-day PA 309 to Hazleton. Most of the former US 309 between Allentown and Hazleton became a rerouted PA 29, which previously followed present-day PA 309 between the two cities, and is now PA 873, PA 248, US 209, and PA 93. US 309 was realigned to Fort Washington Expressway in 1960 to head to a new southern terminus at US 611 (Broad Street) and Stenton Avenue in Philadelphia and was also realigned to bypass Allentown. US 309 was shifted to follow present-day PA 309 between Allentown and Pleasant Corners in 1962, with PA 100 extended north along the former alignment between Fogelsville and Pleasant Corners. In 1963, the northern terminus of US 309 was cut back to US 6 in Tunkhannock. US 309 was decommissioned in 1968 and replaced with PA 309. In the 1980s, the termini of PA 309 were moved to their present locations. PA 309 was realigned to follow I-81 and North Cross Valley Expressway through the Wilkes-Barre area in 1991.

History

U.S. Route 309
Location	Philadelphia – Tunkhannock
Length	142.25 mi (228.93 km)
Existed	1926–1968

The portion of PA 309 between Philadelphia and the Lehigh Valley follows the routing of a Native American path now referred to as the "Minsi Trail" that dates back to the 18th century. This path, named after the Minsi Indians, connected the Blue Mountains to areas to the south. A highway called the King's Road was created between Philadelphia and Bethlehem in the 1760s along the route of the Minsi Trail; the first trip along this road was made by stage wagon in 1763. In 1804, a turnpike called the Bethlehem Turnpike was created to run between Philadelphia and Bethlehem. The turnpike was authorized to collect tolls in 1834, with many of its tollgates erected. The Bethlehem Pike became a free road in 1904 and tolls were removed in 1910.

Following the passage of the Sproul Road Bill in 1911, what would become US 309 was designated as Legislative Route 153 between Philadelphia and Allentown, Legislative Route 163 between Allentown and Mauch Chunk (present-day Jim Thorpe), part of Legislative Route 162 between Mauch Chunk and Nesquehoning, and Legislative Route 170 between Nesquehoning and Wilkes-Barre. Meanwhile, the present-day corridor of PA 309 between Schnecksville and Tamaqua was designated as Legislative Route 226, between Tamaqua and Hazleton as Legislative Route 185, and between Wilkes-Barre and Bowman Creek as part of Legislative Route 11. With the creation of the U.S. Highway System in 1926, US 309, a spur of US 9, was designated to run from US 120/PA 13 in Philadelphia north to US 11/PA 19 in Wilkes-Barre. From Philadelphia, the route followed Bethlehem Pike north through Spring House, Montgomeryville, Sellersville, and Quakertown to Center Valley. From here, US 309 continued northwest to Allentown and passed through the city along Jordan Street, 5th Street, Auburn Street, Lehigh Street, 7th Street, Hamilton Street, 17th Street, Liberty Street, and 19th Street.

North of Allentown, the route continued west along Walbert Avenue before turning north at Walbert and passing through Schnecksville, Neffs, and Slatington. US 309 crossed the Lehigh River and continued north along the east bank of the river through Palmerton and Bowmanstown to Weissport, where it intersected US 209. At this point, US 309 headed west concurrent with US 209 through Lehighton, Mauch Chunk, Nesquehoning, Lansford, and Coaldale to Tamaqua. At Tamaqua, US 309 split from US 209 and headed north through McAdoo, Hazleton, Mountain Top, and Ashley to Wilkes-Barre. In Wilkes-Barre, US 309 followed Hazle Avenue, Park Avenue, South Street, and River Street to its terminus at US 11/PA 19. In 1927, PA 12 was designated concurrent with US 309 between Philadelphia and Center Valley while PA 22 was designated concurrent with US 309 between US 22/PA 3 in Allentown and US 11/PA 19 in Wilkes-Barre. The section of present-day PA 309 between southeast of Dallas and Bowman Creek was designated as part of the northern section of PA 62 in 1927.

Existed	1928–1930

By 1928, US 309 was shifted to a more direct alignment between Nesquehoning and Hazleton. By this time, the entire length of US 309 was paved while the state highway was under construction between Quakertown and Center Valley and for a distance to the north of Hazleton. In 1928, the present-day alignment of PA 309 between Schnecksville and Hazleton was designated as part of PA 29 while part of PA 92 was designated along the present-day section of PA 309 from southeast of Dallas north to Bowman Creek, replacing PA 62. At this time, this portion of PA 29 was paved between US 309 in Schnecksville and PA 143 in New Tripoli and between PA 925 south of Tamaqua and US 309 in Hazleton while PA 92 was paved to a point north of Dallas. In 1928, PA 312 was designated concurrent with US 309 between PA 12 in Center Valley and US 22/PA 3 in Allentown while PA 130 replaced the concurrent PA 22 designation north of Allentown. The under construction portions of US 309 between Quakertown and Center Valley and to the north of Hazleton were completed by 1930 while the concurrent PA 12, PA 312, and PA 130 designations were removed from US 309 by 1930. In 1929, the American Association of State Highway Officials (AASHO) approved extending US 309 north from Wilkes-Barre to South Waverly. In 1930, US 309 was extended north from Wilkes-Barre to NY 17 (Chemung Street) in Waverly, New York. From Wilkes-Barre, the route followed the former alignment of US 11 along River Street and River Road to Pittston. US 309 ran northwest concurrent with US 11 to West Pittston, where it continued northwest along the former alignment of PA 29 parallel to the Susquehanna River to an intersection with US 6 in Osterhout. From here, US 309 ran northwest concurrent with US 6 through Tunkhannock and Wyalusing to Towanda. In Towanda, US 309 split from US 6 and headed north concurrent with US 220 through Athens, Sayre, and South Waverly before US 220/US 309 crossed into New York and ended at NY 17. By 1930, PA 29 was under construction from Blue Mountain to south of Tamaqua.

PA 309 northbound near Hatfield

The southern terminus of US 309 was extended from its previous location at US 422 (Germantown Avenue) in the Chestnut Hill section of Philadelphia to US 1 Byp./US 13 Byp./US 422 at Ridge Avenue and City Line Avenue in Philadelphia by 1940, following US 422 Byp. along Germantown Avenue before heading south along Allens Lane and Lincoln Drive. By 1940, the alignment of US 309 in Allentown was shifted to follow 7th Street and US 22 along Tilghman Street to 19th Street while the alignment in Wilkes-Barre was shifted at South Street to follow Washington Street, Butler Street, Main Street, and Courtright Street to River Street. By 1940, US 309 was widened to a multilane road between PA 73 in Whitemarsh and Allentown, along the US 209 concurrency between Lehighton and Packerton, for a short distance in Mountain Top, between Ashley and Wilkes-Barre, between Wilkes-Barre and US 11 in Pittston, along the US 6 concurrency between PA 92 and PA 29 in Tunkhannock and a stretch to the northwest of Tunkhannock, and along the US 220 concurrency between Athens and Sayre. By this time, the entire length of PA 29 between Schnecksville and Hazleton was paved, with the route realigned to bypass New Tripoli along the present-day alignment of PA 309 and the stretch across Blue Mountain and between PA 925 in South Tamaqua and US 209 in Tamaqua widened to a multilane road. The section of PA 115 between Wilkes-Barre and PA 92 near Luzerne that would later become part of US 309 was widened to a multilane road while the section of PA 92 between north of Dallas and PA 29 in Bowman Creek was paved.

PA 309 northbound in Montgomery Township

In the 1940s, US 309 was shifted to a new alignment between Ashley and Tunkhannock. From Ashley, US 309 was realigned to head through Wilkes-Barre along newly-built Wilkes-Barre Township Boulevard, Spring Street, and Scott Street to PA 115, where it became concurrent with PA 115 along Kidder Street, Butler Street, Main Street, Courtright Street, and River Street to Pierce Street. From here US 309/PA 115 followed Pierce Street across the Susquehanna River to Kingston, where the two routes followed US 11 along Wyoming Avenue and then Union Street before continuing to Luzerne. Past Luzerne, US 309 split from PA 115 and followed the former alignment of PA 92 to Bowman Creek and the former alignment of PA 29 to US 6 in Tunkhannock. The former alignment of US 309 between Wilkes-Barre and Tunkhannock became an unnumbered road between Wilkes-Barre and Pittston and PA 92 between West Pittston and Tunkhannock. In 1948, US 309 was dedicated as the Joseph W. Hunter Highway in honor of the first highway commissioner in Pennsylvania. By 1950, US 309 was widened to a multilane road for a short stretch north of Philadelphia, along its new alignment between Ashley and Wilkes-Barre, between Luzerne and PA 415 in Dallas, and along the US 6 concurrency between PA 87 in Russel Hill and PA 267 in Meshoppen while PA 29 was widened to a multilane road between PA 895 in Snyders and PA 443, between US 209 in Tamaqua and Ginther, and between McAdoo and Audenried.

In the 1950s, US 309 was moved to a different alignment between Allentown and Hazleton. The route followed 7th Street and MacArthur Road before heading west along with US 22 on the Lehigh Valley Thruway to Fogelsville. From Fogelsville, US 309 turned north and replaced PA 100 between Fogelsville and Pleasant Corners and PA 29 between Pleasant Corners and Hazleton. The former alignment of US 309 between Allentown and Hazleton became an unnumbered road between Allentown and Walbert and a realigned PA 29 between Walbert and Hazleton; PA 29 between Walbert and Hazleton is now PA 309 between Walbert and Schnecksville, PA 873 between Schnecksville and Lehigh Gap, PA 248 between Lehigh Gap and Weissport, US 209 between Weissport and Nesquehoning, and PA 93 between Nesquehoning and Hazleton. The section of PA 29 between Schnecksville and Pleasant Corners became unnumbered following the realignment of PA 29. By 1960, US 309 was widened to a multilane road between Hazleton and Mountain Top, between PA 415 in Dallas and Kunkle, and along the US 6 concurrency between north of Tunkhannock and PA 87 in Russel Hill and was upgraded to a divided highway along the PA 443 concurrency south of Tamaqua, between PA 45 in Hometown and McAdoo, between Audenried and Hazleton, along multiple short stretches between Hazleton and Mountain Top, and between Mountain Top and Ashley, and for a stretch along the US 6 concurrency to the north of PA 87 in Russel Hill.

PA 309 northbound approaching its interchange with PA 113 in Hilltown Township

Planning for the route began in the late 1950s. North of Philadelphia, the Fort Washington Expressway from the PA 73 interchange to US 309 (Bethlehem Pike) north of Spring House was built in 1958; the rest of that freeway from PA 73 south to PA 152 in Wyncote was built in 1960. Upon completion of Fort Washington Expressway, US 309 was rerouted to follow Fort Washington Expressway before continuing south along Ogontz Avenue and Stenton Avenue to end at US 611 (now PA 611) at Broad Street in North Philadelphia; US 309 replaced the PA 152 designation along Ogontz Avenue and Stenton Avenue. There were plans made by the Philadelphia City Planning Commission from the late 1940s until the mid 1970s to extend the Fort Washington Expressway south to Center City Philadelphia. The freeway was planned to continue south from its current terminus in Wyncote into Philadelphia and intersect US 1 (Roosevelt Expressway) before terminating at a proposed Girard Avenue Expressway. In 1969, it was estimated the freeway between Wyncote and US 1 would cost $50 million and be completed by 1975 while the freeway between US 1 and the Girard Avenue Expressway would cost $44 million and be completed by 1985. The southern extension of the Fort Washington Expressway was never built due to rising construction costs and community opposition.

On July 1, 1977, the Pennsylvania Department of Transportation (PennDOT) halted spending on proposed highway projects, and the Fort Washington Expressway extension was removed from plans by the Philadelphia City Planning Commission. There were also plans to extend the Fort Washington Expressway northwest and connect to the Pennsylvania Turnpike Northeast Extension before the freeway would continue northeast and connect to the southern terminus of the Sellersville Bypass. In 1983, a scaled-down proposal called for the Fort Washington Expressway to be extended north and end at the Pennsylvania Turnpike Northeast Extension near Lansdale. Interchanges along this proposed extension were to be located at Bethlehem Pike, North Wales Road, PA 63, and PA 463.

A freeway bypass of to the west of Allentown from US 309 in Lanark to US 22 near Walbert was built in 1958. Upon completion of this bypass, US 309 was rerouted to follow it from Lanark north to US 22, PA 29 was designated onto the bypass north of Cedar Crest Boulevard and continued north as a divided highway to north of Walbert, and US 222 was designated onto the bypass from Hamilton Boulevard to its terminus at US 22. The former alignment of US 309 through Allentown became unnumbered until it was designated as a southern extension of PA 145 in 1991. On June 18, 1962, AASHO approved the realignment of US 309 to the modern-day alignment of PA 309 between US 22 near Allentown and Pleasant Corners, following PA 29 between Allentown and the intersection with present-day PA 873 in Schnecksville before heading west between Schnecksville and Pleasant Corners. PA 100 was extended north from Fogelsville to Pleasant Corners along the former alignment of US 309. The concurrent PA 29 designation was removed from US 309 between Allentown and Schnecksville in 1966. US 222 was also removed from US 309 in the 1960s.

PA 309 northbound past PA 63 in Horsham Township

The north end of US 309 between Tunkhannock and Waverly, New York, had always been shared with other U.S. Highways (US 6 and US 220). On June 19, 1963, AASHO approved the removal of the US 309 designation between US 6 in Tunkhannock and the New York border, eliminating the concurrencies with US 6 and US 220. This truncation left the northern terminus of US 309 at US 6 in 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 AASHO, which discourages routes within a single state. On October 14, 1967, AASHO approved the elimination of the US 309 designation. 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 a freeway for US 309 to bypass Sellersville from just north of the border between Montgomery and Bucks counties to just south of Quakertown. This bypass opened in 1969 as part of PA 309. By 1970, PA 309 was upgraded to a divided highway between the north end of the Fort Washington Expressway and US 202 (Dekalb Pike) in Montgomeryville, US 202/PA 463 in Montgomeryville and the south end of the Sellersville Bypass, the north end of the Sellersville Bypass and the south end of the freeway bypass of Allentown in Lanark, and Luzerne and PA 415 in Dallas. By 1980, PA 309 was realigned through the Wilkes-Barre area to follow PA 315 along Blackman Street, Hazle Avenue, Park Avenue, South Street, River Street, Market Street, and US 11; an extended PA 315 was designated onto the former portion of PA 309 along Wilkes-Barre Township Boulevard, Spring Street, and Scott Street while an extended PA 115 was designated onto the former portion of PA 309 along Kidder Street, Butler Street, Main Street, Courtright Street, River Street, and Pierce Street. By 1989, the northern terminus of PA 309 was cut back from US 6 in Tunkhannock to its current location, eliminating the concurrency with PA 29 between Bowman Creek and Tunkhannock. Also by this time, PA 309 was rerouted to follow Cheltenham Avenue to reach its current southern terminus at PA 611 instead of following Ogontz Avenue and Stenton Avenue to PA 611. By 1989, PA 309 was upgraded to a divided highway along the concurrency with US 202 (now US 202 Bus.) in Montgomeryville. In 1989, the PA 309 freeway bypass of Allentown between Lanark and north of US 222 became part of I-78.

On June 21, 1960, plans were announced to construct the North Cross Valley Expressway to link the Back Mountain region to I-81 in Luzerne County. Construction on the highway began in 1964. The North Cross Valley Expressway was built in stages. The section of the highway from River Street in Plains Township across the Susquehanna River to Rutter Avenue in Kingston was constructed in 1976 and opened in 1977. The section of the North Cross Valley Expressway between Rutter Avenue in Kingston and PA 309 in Luzerne was constructed in 1980. During construction of this section in 1979, a coal vein was discovered. In 1982, construction began to complete the bridge linking the terminus of the expressway at River Street to Conyngham Avenue. By 1989, PA 309 was rerouted to follow Wilkes-Barre Township Boulevard, Spring Street, Scott Street, Kidder Street, Conyngham Avenue, Wilkes-Barre Boulevard, and the North Cross Valley Expressway through the Wilkes-Barre area; the route replaced the PA 315 designation along Wilkes-Barre Township Boulevard, Spring Street, and Scott Street and the PA 115 designation along Kidder Street. The remaining section of the North Cross Valley Expressway from Wilkes-Barre Boulevard to I-81 was completed on November 9, 1991, with Governor Robert P. Casey in attendance for a ribbon-cutting ceremony. Construction of the highway cost $100 million. Upon the completion of the final section of the North Cross Valley Expressway, PA 309 was rerouted to follow I-81 and the North Cross Valley Expressway through the Wilkes-Barre area, while PA 309 Bus. was designated onto the former alignment of PA 309 along Wilkes-Barre Township Boulevard, Spring Street, and Scott Street and replaced PA 115 along Kidder Street between Scott Street and the interchange with the North Cross Valley Expressway.

PA 309 northbound at southern terminus of the Fort Washington Expressway at the PA 152 exit in Cheltenham Township

PennDOT undertook a $375 million project to reconstruct and improve the section of PA 309 running along the Fort Washington Expressway between Cheltenham Avenue and PA 63 in Montgomery County. The project rebuilt the roadway and shoulders, reconstructed bridges, improved ramps at interchanges, and constructed sound walls. The interchanges with PA 152 and the Pennsylvania Turnpike (I-276) and Pennsylvania Avenue were completely reconstructed and reconfigured while a southbound exit and northbound entrance were added at the Norristown Road interchange. As part of the reconstruction of the interchange between PA 309 and the Pennsylvania Turnpike (I-276) and Pennsylvania Avenue, Pennsylvania Avenue was extended as a two-way road between Fort Washington and Oreland, with traffic between the two communities no longer having to travel along PA 309 between the two sections of Pennsylvania Avenue. The section of the highway between PA 73 and Highland Avenue was reconstructed between February 2004 and November 2006. The interchange between PA 309 and the Pennsylvania Turnpike (I-276) and Pennsylvania Avenue in Fort Washington was reconstructed between January 2005 and November 2008. The portion of the highway between Cheltenham Avenue and PA 73 was rebuilt between March 2005 and November 2008. The section of PA 309 between Highland Avenue and PA 63 was reconstructed between July 2007 and early 2011. The new ramps at the Norristown Road interchange opened on December 20, 2010.

On November 11, 2019, work began on a project to improve the section of PA 309 along the Sellersville Bypass in Bucks County by rehabilitating pavement and reconstructing structures. Construction on this improvement project was completed in 2023.

There are plans to convert the intersection with West Saucon Valley Road/Center Valley Parkway in Upper Saucon Township into an interchange. Construction is planned to begin in the later part of 2026, with completion expected in 2030.
