PennDOT widens Route 422, four bridges
Final construction activities are scheduled under a project to build new, wider bridges to improve travel.
KING OF PRUSSIA » Get ready for more congestions on Route 422, but PennDOT officials say the temporary delays will be worth it.
Final construction activities are scheduled under a project to build new, wider bridges to improve travel and carry Route 422 motorists over the Schuylkill River, Norfolk Southern Railroad, South Trooper Road and Schuylkill River Trail in West Norriton, Upper Merion and Lower Providence townships.
Alternating left- and right-lane closures are planned on westbound Route 422 between the Route 202 and Oaks interchanges on Tuesday, Dec. 15, through Friday, Dec. 18, from 7 p.m. to 6 a.m. the following morning.
Motorists are advised to allow extra time when traveling through the work area because backups and delays will occur. All scheduled activities are weather dependent.
Construction on this improvement project began in February 2016 to widen and improve U.S. 422 and replace four Schuylkill River bridges.
The new bridges provide a total width of approximately 146 feet, wide enough for eight travel lanes. The structures currently carry six lanes — three eastbound and three westbound. There are two through lanes in each direction plus a third lane on both sides for motorists to use to travel between the Route 363 and Route 23 interchanges.
The new bridges are wide enough for the possible addition of a third through lane in each direction sometime in the future, PennDOT says.
