In the Commonwealth of Pennsylvania, U.S. Route 202 runs through the Concordville/Chadds Ford area of Delaware County, bypasses Chester County seat West Chester, intersects the Pennsylvania Turnpike at King of Prussia in Montgomery County, then makes its way through Norristown and Doylestown before crossing the Delaware River into New Jersey. It is concurrent with U.S. Route 322 from Concordville to West Chester, and from south of West Chester to King of Prussia it is a full freeway.
