The Route 29 (Morehall Road) sinkhole remediation project will provide a long-term solution to address repeat sinkholes that have occurred within the roadway. Work will be completed along Route 29 (Morehall Road) in East Whiteland Township, Chester County between Great Valley Parkway and the I-76 (PA Turnpike eastbound) on-ramp, north of Atwater Drive. The proposed scope of work includes 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 proposed work for this project includes drainage pipe replacement and lining, stabilization and lining of roadside swales, and pavement reconstruction.

Construction is anticipated to last between 6 to 8 months at the project location. Temporary traffic control patterns will be implemented to provide a safe work zone during construction. Route 29 will utilize staged half-width construction and will maintain traffic in each direction during construction. Temporary traffic signal configurations will also be provided during construction. 

The Department is completing public outreach to adjacent owners and businesses and will coordinate construction activities to maintain access to all connecting properties. Updates and future project briefings will be provided as the project progresses. Construction is anticipated to begin in early fall 2024.
