According to a release issued by PennDOT, drivers heading west on U.S. Route 422 this weekend will find the westbound two lanes reduced to one between the Pennsylvania Turnpike overpass and First Avenue Interchange in Tredyffrin. The lane closure will be in effect from 8 p.m. today through 5 a.m. Monday, May 2, for construction.
Route 422’s westbound right lane will be restricted during the weekend while crews drill and pump grout beneath the highway. Drivers are advised to allow additional time to travel west on Route 422 or use an alternate route.
This operation is part of PennDOT’s $2.7 million project to repair Route 422 and fill underground voids that could potentially develop into sinkholes. Construction began in February and will finish in June.
Crews are working to drill more than 425 holes in the road and median of Route 422 and pump grout to support the pavement and fill underground cavities.
In addition to this compaction grouting operation, covering a distance of 500 feet, the contractor will replace a deteriorated concrete slab on the eastbound side of the highway, install a liner in the grass median to seal the surface to block water penetration, and resurface 1,800 feet of Route 422 between the First Avenue and Pennsylvania Turnpike overpasses.
J.D. Eckman Inc. of Atglen, Chester County, is the general contractor on the $2,691,198 contract, which is financed with 100 percent federal funds.
