United States Route 1 and Pennsylvania Route 63 join for a mile-long duplex through Philadelphia in Philadelphia County.
Southbound on US 1 on the Roosevelt Boulevard entering Philadelphia. Roosevelt Boulevard is an urban arterial highway with frontage roads on either side. Right turn access to side roads from the main through lanes is achieved by following diagonal crossovers to the frontage road and turning from there. At the eastern split of US 1/PA 63 in this photo, US 1 traffic must cross over to the frontage road.
Once on the multi-lane frontage road, a right turn onto a cloverleaf ramps leads to PA 63 east. PA 63 west joins US 1 ahead.
Heading westward on US 1/PA 63's frontage road at Comly Road.
Continuing on the frontage road. PA 63 west is mentioned on the right.
Now back on the mainline, one must cross over to the frontage road to follow PA 63 west.
PA 63 west makes a right turn from the frontage road.
Now northbound on US 1 at the western split. A left turn leads to PA 63, and thus no frontage road is needed for this access.
A closer view of the intersection. PA 63 joins US 1 here.
Reassurance shields are posted in the median that divides the main carriageways.
PA 63 east crosses over to the frontage road to exit at the eastern split.
PA 63 east leads to I-95.
