MONTGOMERY COUNTY, PA — A key Norristown intersection will shut down this weekend as PennDOT advances a sweeping $55.1 million reconstruction of U.S. 202 (Dekalb Pike), a long-term project that is reshaping one of Montgomery County’s busiest travel corridors.
PennDOT said the Johnson Highway and Arch Street/Old Arch Road intersection will close from 6:00 AM Sunday, November 23, until 5:00 AM Monday, November 24, for roadway construction and paving. The shutdown is expected to trigger heavy congestion across surrounding routes.
During the closure, eastbound Johnson Highway traffic will be detoured to U.S. 202 and either Germantown Pike or Fornance Street. Westbound traffic will be directed to New Hope Street and Fornance Street or New Hope Street/Arch Road to Germantown Pike. Arch Street and Old Arch Road drivers will be detoured via New Hope Street and Fornance Street. Local access will be maintained up to the construction limits. All work is weather dependent.
The wider project will completely rebuild approximately 1.8 miles of U.S. 202 in Norristown, East Norriton, and Whitpain townships. Upgrades include widening the roadway to add new lanes, installing five-foot bicycle lanes, building sidewalks, reconstructing a bridge and box culvert, installing sound and retaining walls, modernizing signals, improving drainage, and integrating Intelligent Transportation Systems to manage traffic flow.
PennDOT also reminded drivers that Germantown Pike will remain reduced to a single lane in each direction between Swede Road and Hannah Avenue through July 2027 as part of related improvements. Work will continue in stages to preserve local access and maintain traffic, but the agency warned that backups and slowdowns will occur throughout the construction zone.
The U.S. 202 initiative is one phase of a multi-year effort to upgrade a 9.1-mile stretch of the corridor connecting Norristown to Route 309.
