US 1(N-S)/Old PA 100(S-N) Duplex
United States Route 1 and Pennsylvania Route 100 used to join for a short (< 0.25 mi) duplex through Chadds Ford in Delaware County. PA 100 was decommissioned in 2003, redesignated SR 3101, and locally known as Creek Road.
Southbound on Creek Road in 2003 after PA 100 was decommissioned on this stretch of roadway. The PA 100 shield used to be posted here between the US 1 shields. The western split is just ahead.
Just ahead, PA 100 south used to turn left onto US 1 north, making a wrong-way duplex. The duplex is now a secondary route duplex (SR 0001/SR 3101).
