    Construction Continues on Route 420 (Wanamaker Avenue) Bridge Replacement Project in Delaware County

    November 17, 2023

    King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that bridge construction activities will reduce northbound Route 420 (Wanamaker Avenue) to a single lane under a $35.8 million project to replace the bridges that carry Route 420 (Wanamaker Avenue) over Darby Creek in Prospect Park Borough and Tinicum Township, Delaware County.

    Weather permitting, motorists are advised of the following travel restriction:

    Drivers are reminded that southbound Route 420 (Wanamaker Avenue) will be reduced to a single lane between 4th Avenue and I-95 until the new structures are complete.

    During the long-term lane closure, oversized vehicles over 10-feet-wide will be prohibited from using southbound Route 420 (Wanamaker Avenue) through the project limits. Drivers will be directed to use U.S. 13 (Chester Pike), Stewart Avenue and Route 291 (Industrial Highway) to access Route 420 (Wanamaker Avenue) south of I-95.

    In addition, access to southbound Route 420 (Wanamaker Avenue) from Lazaretto Road will be prohibited for all motorists. Motorists will be directed to follow the posted detour route to access southbound Route 420 (Wanamaker Avenue).

    Access to northbound and southbound Route 420 (Wanamaker Avenue) from Lafayette Avenue at 2nd Avenue will be prohibited for all motorists except emergency vehicles. Motorists will be directed to follow the posted detour routes to access northbound and southbound Route 420 (Wanamaker Avenue).
