In Chester County, before the US 1 expressway was built there, US 1 continued up Baltimore Pike (which now has a dead-end section in Nottingham where northbound US 1 veers away from the Baltimore Pike alignment onto the expressway). In Oxford, US 1 northbound ran on S. 3rd Street, then turned right on Market Street (PA 472) (N. 3rd Street is the beginning of PA 10), then very quickly turned left onto Lincoln Street, and after leaving Oxford the road ran by Lincoln University. Approaching Avondale, Baltimore Pike traffic bent southeast along Pennsylvania Avenue (PA 41), then Baltimore Pike split off after Avondale. In the town of Kennett Square, northbound US 1 ran along Cypress Street (southbound US 1 ran along State Street), and those streets were marked E-W, not N-S. After Kennett Square, the US 1 expressway ends and its traffic merges onto Baltimore Pike. Except for the southernmost part of Baltimore Pike at Nottingham, the Chester County part of old US 1 is still driveable. There is the dead end mentioned above; also, a small part of Baltimore Pike is permanently blocked by the Herr's Snacks company property.
