Some scans I spliced together from a 1991 Franklin County street atlas for Bucks and Montgomery Counties showing some proposals that were likely long dead at the time of publication. The key maps reveal even more proposals that do not translate onto the street-level maps. Click on the images for larger views.
The US 202 (Piedmont Expressway?) alignment shows up on the Bucks County key map (extracted from their regional map) as well as a proposed for a highway from PA 9 at Kulpsville to US 202. Note also the freeway spur from I-95 at Bristol.
A look at the US 202 freeway proposed southwest of what was a half-used cloverleaf interchange (until the current Parkway project was underway) at Doylestown.
The map also shows the US 202 freeway continuing northeast from Doylestown to New Jersey.
This atlas was the first I saw of a new alignment for PA 611 in northern Bucks County.
The US 202 alignment continues onto Montgomery County key map. Also one of the Philadelphia freeway proposals is visible to the bottom right.
