No detours have been announced, but motorists should expect delays as traffic merges through the active work zones. Plan extra time for travel and seek alternate routes when possible, especially during the evening and overnight hours.

PennDOT said the milling and paving work between the Route 100 and Armand Hammer Boulevard interchanges has been added to its ongoing $83.6 million project to reconstruct and improve approximately 2.1 miles of the expressway and replace bridges between the Sanatoga Interchange and Porter Road in Lower Pottsgrove Township.
