Northbound on Truck US 19 at the interchange with PA 51/Saw Mill Run Boulevard. Truck US 19 turns left to join PA 51 toward I-279. This junction was upgraded from an at-grade intersection to an interchange in 1999.

Denny Pine 2003

Two miles to the north, Truck US 19/51 meets I-279/US 22/US 30 and US 19. Truck US 19 north splits from PA 51 north here by joining I-279 south, creates a complicated multiplex with I-279/US 19/Truck US 19 south/US 22/US 30, and loops around back to the north. US 19 joins PA 51 here toward West End.

 


Denny Pine 2003

The same interchange as seen from US 19/PA 51 south. US 19 exists PA 51, and Truck US 19 joins it straight ahead.
