PA 309 travels north from PA 611 (Old York Road) along the Philadelphia city line to PA 29 (Joseph W Hunter Highway) in Monroe township. The state route was formerly a part of U.S. 309, which was decommissioned in 1968.

Through southeastern Pennsylvania, PA 309 follows the Fort Washington Expressway, a limited access highway from Cheltenham township to Fort Washington, Ambler and Spring House. The state route continues north along Bethlehem Pike to Montgomeryville and Hatfield township. PA 309 upgrades to a freeway again along the Sellersville Bypass from Souderton north to Teldford, Sellersville and East Rockhill township.

North into Quakertown, PA 309 follows a commercialized stretch along West End Boulevard. The five lane arterial extends north to 3rd Street at Coopersburg. PA 309 turns northwest through Upper Saucon township to become a part of Interstate 78 south of Allentown.

The freeway along PA 309 around Allentown was incorporated into Interstate 78. I-78 was completed south of Bethlehem and Easton in 1989. PA 309 extends north from I-78 to U.S. 22 (Lehigh Valley thruway) along an older freeway bypass of Allentown to South Whithall township.

The remainder of PA 309 north to Hazleton generally constitutes a two lane highway with exceptions through North Whitehall township. The state route branches west from I-476 at Schnecksville to Pleasant Corners and U.S. 209 at Tamaqua.

PA 309 parallels the Interstate 81 corridor north from there into Wilkes-Barre, where it combines with the freeway east to PA 115 and the North Cross Valley Expressway.

The North Cross Valley Expressway is an urban freeway spanning the city of Wilkes-Barre west to the boroughs of Kingston, Forty Fort, Pringle and Luzerne.
