One quarter mile east of the loop ramp onto Pennsylvania 309 southbound (Exit 60A). Pennsylvania 309 represents a major corridor between Allentown-Bethelehem and the north Philadelphia suburbs of Quakertown, Sellersville, Hatfield, Montgomeryville, Ambler, and Fort Washington. The state route varies between a four to six lane surface arterial and full freeway on the 34-mile drive to Interstate 276 (Pennsylvania Turnpike) at Fort Washington. Photo taken 04/23/04.
Six lanes of Interstate 78 & Pennsylvania 309 skirt the southern reaches of the Allentown city limits between South Mountain Park and the Allentown Queen City Municipal Airport. The overlapped routes encounter Emmaus Avenue (Exit 58) in the Waldheim Park section of the city. Photo taken 06/01/04.
One half mile out from the loop ramp of Exit 58 onto Emmaus Avenue southbound. Emmaus Avenue becomes Dalton Street at the Allentown and Emmaus (pop. 11,242) city line south of Interstate 78 & Pennsylvania 309. Photo taken 06/01/04.

The first sign of the impending split of Pennsylvania 309 northbound from Interstate 78 west (Exit 53) is posted ahead of the junction with U.S. 222 & Pennsylvania 222 (Exits 54B/A). There is no direct connection between Interstate 78 and the Pennsylvania Turnpike Northeast Extension (Interstate 476). Motorists must still use the original Lehigh Valley Interchange of the Turnpike with U.S. 22 (Lehigh Valley Thruway). Pennsylvania 309 interchanges with the Lehigh Valley Thruway just east of Interstate 476. Photo taken 06/01/04.
The Exit 54B off-ramp for Pennsylvania 222 (erroneously signed as U.S. 222) northbound (Hamilton Boulevard) departs Interstate 78 west at the Hillview Road overpass. U.S. 222 used to continue northwest into Allentown itself to meet its parent U.S. 22. However the route saw truncation some time ago and now Pennsylvania 222 continues Hamilton Boulevard northward to Pennsylvania 145 in downtown Allentown. Photo taken 06/01/04.
Traffic from U.S. 222 (Hamilton Boulevard) northbound merges onto Interstate 78 west & Pennsylvania 309 north ahead of the loop ramp of Exit 54A. The southbound beginning of U.S. 222 carries travelers out of Dorneyville to Wescosville, Trexlertown, and Breinigsville in the western suburbs of Allentown. Photo taken 06/01/04.
