UPPER MERION — The Pennsylvania Department of Transportation (PennDOT) announced that construction will begin on Monday, January 13, on a $22.4 million project to provide long-term sinkhole remediation on Route 29 (Morehall Road) in East Whiteland Township, Chester County,and U.S. 202 (DeKalb Pike) in Upper Merion Township, Montgomery County to ensure a safe and efficient transportation system for the traveling public.
Under this project, PennDOT’s contractor will utilize a limited mobility grouting program, which will involve drilling a series of holes through the pavement in a “grid” pattern. Pressurized grout will be injected into the drilled holes to fill subsurface voids beneath the roadway. The filling of subsurface voids will help stabilize the ground beneath the pavement and will reduce the risk of future sinkholes. Additional work includes drainage improvements and pavement reconstruction.
Beginning, Monday, January 13, motorists are advised of the following travel restrictions:
- Monday, January 13, through Friday, January 31, from 9 a.m. to 3 p.m., a weekday right lane closure is scheduled on southbound U.S. 202 (Dekalb Pike) between Saulin Boulevard/Prince Frederick Boulevard and Ivy Lane for sidewalk reconstruction.
- Monday, January 13, through late February, from 9 a.m. to 3 p.m., weekday lane closures and shifts are scheduled in both directions on Route 29 (Morehall Road) between Great Valley Parkway and the Pennsylvania Turnpike Interchange for median removal and sinkhole remediation.
Drivers are advised to allow extra time when traveling through the work areas because backups and delays will occur. All scheduled activities are weather dependent…
