Today, parts of the road are signed as U.S. Route 1 (US 1), US 13, and a small portion of Pennsylvania Route 41 (PA 41). A section of the road within the city limits of Philadelphia and surrounding boroughs is known as Baltimore Avenue, although locals are known to call the Delaware County portion "Baltimore Pike". In suburbs farther west, some sections retain the formal name "Baltimore Pike." Today, Baltimore Avenue's eastern terminus is at 38th Street in Philadelphia, where it intersects with Woodland Avenue (from Southwest Philadelphia and the borough of Darby) and funnels into University Avenue. The road used to continue to Market Street until the University City area was redeveloped.
The name Baltimore Pike is given to a section of US 1 Bus. in Harford County between Benson and Main Street in Bel Air. South of Benson, US 1 is named Belair Road. From Main Street, US 1 Bus. follows several streets of various other names before joining with US 1 as Conowingo Road.
