 The highway was left at that until 1999 when construction began on a final segment that would connect the US 22 interchange to I-78.The final three-mile (5 km) stretch opened in January 2002.In January 2004, the expressway was shut down between Lower Nazareth Township (PA 248) and Stockertown (PA 191) because of a sinkhole that was in the area of the Bushkill Creek directly under a northbound bridge support beam.
