PennDOT plans to widen a stretch of Interstate 78 in Lehigh County to 6 lanes, with nighttime lane closures expected. The project is part of broader roadway improvements in the area, although it is unclear if other nearby projects, such as the Route 22 widening and a potential I-81 expansion, are related or separate initiatives. Details on timelines and funding for these various projects are being shared by PennDOT.
