Across the Delaware River in Philadelphia, a freeway which was to be called the Pulaski Expressway and be designated Pennsylvania Route 90 (PA 90) was to have run from I-95 northwest to Roosevelt Boulevard (US 1).

Route 90 begins at the Pennsylvania-New Jersey border on the Betsy Ross Bridge over the Delaware River, where the road continues into Philadelphia as an unnumbered freeway that heads to an interchange with I-95.

[1][3] Route 90 passes over CR 615 (Union Avenue) before coming to an interchange with US 130, where maintenance is transferred to the New Jersey Department of Transportation.

[1] Plans for the Route 90 freeway were first made in 1964, a year after the Betsy Ross Bridge over the Delaware River was proposed.

A 1970 proposal to include the planned Route 90 freeway as a part of the Interstate Highway System was denied.

[6] The Betsy Ross Bridge itself was finished in 1974, but did not open to traffic until April 30, 1976 due to controversies concerning the approach roads.

Due to financial limitations and feared environmental impacts, the southern extension of Route 90 to Mount Laurel was canceled by 1980.

[11] Vestiges of this extension can be seen from I-95 in the form of stub ramps and the mainline coming to an abrupt end as a barricaded bridge.
