The route runs from an interchange between [[Pennsylvania Route 611|PA 611]] and [[Cheltenham Avenue]] on the border of [[Philadelphia]] and [[Cheltenham Township, Montgomery County, Pennsylvania|Cheltenham Township]] north to an intersection with [[Pennsylvania Route 29|PA 29]] in [[Bowman Creek, Pennsylvania|Bowman Creek]], a village in [[Monroe Township, Wyoming County, Pennsylvania|Monroe Township]] in [[Wyoming County, Pennsylvania|Wyoming County]]. The highway connects Philadelphia and its northern suburbs to [[Allentown, Pennsylvania|Allentown]] and the [[Lehigh Valley]], and [[Hazleton, Pennsylvania|Hazleton]] and [[Wilkes-Barre, Pennsylvania|Wilkes-Barre]] in [[Wyoming Valley]].
PA 309 heads north from Philadelphia and becomes a [[freeway]] called '''Fort Washington Expressway''' through suburban areas in [[Montgomery County, Pennsylvania|Montgomery County]], passing through [[Fort Washington, Pennsylvania|Fort Washington]], before becoming a surface road called [[Bethlehem Pike]] and running through [[Montgomeryville, Pennsylvania|Montgomeryville]]. In [[Bucks County, Pennsylvania|Bucks County]], the route has a freeway section bypassing [[Sellersville, Pennsylvania|Sellersville]] before passing through [[Quakertown, Pennsylvania|Quakertown]] as a surface road. PA 309 then enters the Lehigh Valley, where it joins [[Interstate 78 in Pennsylvania|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, Pennsylvania|Tamaqua]] before it reaches Hazleton. PA 309 heads into Wyoming Valley and passes through the Wilkes-Barre area on a freeway alignment along [[Interstate 81 in Pennsylvania|I-81]] and the '''North Cross Valley Expressway''' before turning into a surface road again, where it runs through [[Dallas, Pennsylvania|Dallas]] before reaching its northern terminus.
The surface road sections of the route between Philadelphia and the Lehigh Valley follow a [[toll road|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 [[U.S. Route 120|US 120]] (later renamed [[U.S. Route 422|US 422]]) in the [[Chestnut Hill, Philadelphia|Chestnut Hill]] section of Philadelphia north to [[U.S. Route 11 in Pennsylvania|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, Pennsylvania|Slatington]], [[Palmerton, Pennsylvania|Palmerton]], [[Lehighton, Pennsylvania|Lehighton]], [[Jim Thorpe, Pennsylvania|Jim Thorpe]], and [[Nesquehoning, Pennsylvania|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, Tioga County, New York|Waverly, New York]], heading north to [[Pittston, Pennsylvania|Pittston]] and [[Tunkhannock, Pennsylvania|Tunkhannock]] before following [[U.S. Route 6 in Pennsylvania|US 6]] between Tunkhannock and [[Towanda, Pennsylvania|Towanda]] and [[U.S. Route 220 in Pennsylvania|US 220]] between Towanda and Waverly. By 1940, US 309 was extended south to [[U.S. Route 1 Bypass (Philadelphia, Pennsylvania)|US 1 Bypass]] (US 1 Byp.)/[[U.S. Route 13 Bypass (Philadelphia, Pennsylvania)|US 13 Byp.]]/US 422 at [[Ridge Pike|Ridge Avenue]] and [[City Avenue|City Line Avenue]] in Philadelphia.
In the 1940s, US 309 was realigned between [[Ashley, Pennsylvania|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, Pennsylvania|West Pittston]] and Tunkhannock designated as part of [[Pennsylvania Route 92|PA 92]]. In the 1950s, US 309 was rerouted between Allentown and Hazleton to follow [[U.S. Route 22 in Pennsylvania|US 22]] west to [[Fogelsville, Pennsylvania|Fogelsville]] before turning north to [[Pleasant Corners, Lehigh County, Pennsylvania|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 [[Pennsylvania Route 873|PA 873]], [[Pennsylvania Route 248|PA 248]], [[U.S. Route 209|US 209]], and [[Pennsylvania Route 93|PA 93]]. US 309 was realigned to Fort Washington Expressway in 1960 to head to a new southern terminus at [[U.S. Route 611|US 611]] ([[Broad Street (Philadelphia)|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 [[Pennsylvania Route 100|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.

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, Pennsylvania|Lansdale]].
