Drivers in Delaware County should expect a shift in their usual commute next week, as PennDOT has scheduled a traffic adjustment on Route 420 (Wanamaker Avenue) due to a major bridge replacement project. The project, which crosses Darby Creek and touches both Prospect Park Borough and Tinicum Township, carries a hefty price tag of $36 million, according to the Commonwealth of Pennsylvania PennDOT.
From Monday through Friday, northbound and southbound lanes on Route 420 between I-95 and 4th Avenue will be closed nightly from 7 PM to 7 AM for construction. Motorists should expect delays and plan extra travel time.
Those demanding more details on this significant infrastructure upgrade can find them on the dedicated Route 420 Bridge Replacement webpage. Meanwhile, for those seeking real-time traffic info, the 511PA website and accompanying smartphone app are available, providing updates on traffic delays, weather conditions, speed advisories, and access to more than 1,200 traffic cameras for a more informed commute.
PennDOT’s website provides information on planned and active construction projects in Bucks, Chester, Delaware, Montgomery, and Philadelphia counties. Updates are also available via PennDOT’s social media channels, including Twitter, Facebook, and Instagram.
