I-76(E-W)/US 1(N-S) Duplex

 

Interstate 76 and United States Route 1 join for a mile in western Philadelphia in Philadelphia and Montgomery Counties.

Adam Froehlig

US 1 southbound on the Roosevelt Expressway Extension crossing the Schuylkill River. Upon reaching the western shore, US 1 meets I-76/Schuylkill Expressway at a high-speed interchange. US 1 then briefly joins I-76.

From I-76 west, the US 1 north (Roosevelt Boulevard) mainline joins first at Exit 340B, then US 1 south's mainline (City Avenue) comes a mile ahead at Exit 339. Due to the large traffic volumes and congestion, US 1 south actually exits first, well before traffic from Roosevelt Boulevard merges. The US 1 south exiting traffic parallels I-76/US 1 past the first exit.

 

Timothy Reichard 5/17/03

Traffic for US 1 north exits next to cross the Schuylkill River and join US 1 north on Roosevelt Boulevard.

Next, traffic from US 1/Roosevelt Boulevard merges from the right, and the exit lane for US 1 south rejoins briefly to allow merging US 1 traffic to change lanes to the left and continue on US 1 south. The US 1 south exit lane acts like a short express lane, bypassing the US 1 north interchange. US 1 south splits off to follow City Avenue, which straddles the Philadelphia-Montgomery County Line.

 

Timothy Reichard 5/17/03

The traffic patterns are simpler on I-76 east. First US 1 south exits on the right, directly onto City Avenue.

 

Timothy Reichard 5/17/03

Next, US 1 north merges from the right and then exits to the right onto Roosevelt Boulevard.
