A structurally deficient bridge that carries traffic over the Conemaugh River just across the Indiana County line is slated for major improvements.
Known locally as the Cramer Bridge, work on the concrete span on Route 403 will force a closure of the highway between Route 711 and Route 2013 – Grange Hill Road – beginning Monday.
The posted detour will use Route 56 in Johnstown to Route 22 to Route 403. For local traffic not using the posted detour, it will amount to a distance of about a mile and a half around the bridge, said PennDOT public information officer Deborah Casadei on Monday.
An East Wheatfield Township road, Route T-884, known locally as Deyarmin Road, also will be closed as part of the project, she said.
Built in 1930, the bridge today serves on average 4,686 vehicles daily and replacement is needed because, Casadei said, it has reached the end of its useful life. It will be replaced with a concrete box culvert.
Cost of the project is set at $816,516, with the work being done by J.C. Lee Construction and Supply Center of Petrolia, Butler County, the low bidder.
Work should be competed by the end of May.
In the middle of next week, the Hickory Street Bridge in Johnstown’s Kernville section will close for six months for rehabilitation work on the 230-foot span.
Serving 4,305 vehicles daily, work on the bridge will cost about $4 million.
Along with a vehicular detour, the contractor, Clearwater Construction Co. of Mercer, will provide a pedestrial shuttle from both sides of the closed bridge.
