PennDOT has announced that construction will begin on Monday, September 29, on the $6.8 million project to provide long-term sinkhole remediation on U.S. 30 (Exton Bypass) in West Whiteland and East Caln townships, Chester County.
Motorists are advised of the following travel restriction:
Monday, September 29, though, Friday, October 3, from 9:00 AM and 3:00 PM, alternating lane closures will be in place on U.S. 30 (Exton Bypass) between Route 100 (Pottstown Pike) and Business U.S. 30 (Lancaster Avenue) for survey operations.
Drivers are advised to allow extra time when approaching the work area because significant backups and delays will occur. The schedule is weather dependent.
Under this project, PennDOT’s contractor will perform permanent repairs to sinkholes at two locations on U.S. 30 (Exton Bypass) between Business U.S. 30 (Lancaster Avenue) and Clover Mill Road.
As part of the remediation, crews 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 under this project includes pavement reconstruction, drainage pipe replacement and stabilization of roadside swales.
Road-Con of West Chester, Chester County, is the general contractor on this project, which is financed with 100 percent federal funds.
