 As a result, PA 272 was extended north from Willow Street to run concurrent with US 222 through Lancaster before following the former surface alignment of US 222 between Lancaster and Adamstown, ending at an intersection with US 222 and PA 568.In 2006, the intersection with US 222 and PA 568 at the northern terminus was replaced with an interchange as part of upgrading US 222 to a freeway between Adamstown and Reading.In March 2013, construction began on a new bridge to carry US 222/PA 272 over the Amtrak tracks in Lancaster.
