Pennsylvania Route 23

Pennsylvania Route 23 (PA 23) is a 81.14-mile-long (130.58 km) state highway in southeastern Pennsylvania. The route begins at PA 441 in Marietta and heads east to U.S. Route 1 (US 1) on the border of Lower Merion Township and Philadelphia. PA 23 begins at Marietta in Lancaster County and continues east to Lancaster, where it passes through the city on a one-way pair and intersects US 222 and US 30. East of Lancaster, the route passes through agricultural areas in Pennsylvania Dutch Country, serving Leola, New Holland, and Blue Ball, where it crosses US 322. PA 23 passes through the southern tip of Berks County and serves Morgantown, where a ramp provides access to Interstate 176 (I-176). The route runs through northern Chester County and serves Elverson, Bucktown, Phoenixville, and Valley Forge. PA 23 continues into Montgomery County and intersects US 422 in King of Prussia and US 202 in Bridgeport. The route follows the Schuylkill River to West Conshohocken, where it has access to I-76 and I-476, before it continues southeast through Lower Merion Township to US 1.
