Route 29 Reopens After Sinkhole Repairs in Chester County

PennDOT

EAST WHITELAND TWP, PA — Drivers traveling along Route 29 (Morehall Road) in Chester County are seeing relief after PennDOT reopened all lanes in both directions following months of sinkhole remediation work tied to a major infrastructure stabilization project.

At a Glance

  • Roads Affected: Route 29 (Morehall Road), Quarry Hill Road, U.S. 202 (DeKalb Pike)
  • Dates: All lanes reopened; additional work ongoing under Stage 4 construction
  • Times: Future short-term restrictions to be announced
  • Reason: Sinkhole remediation and roadway stabilization

PennDOT said northbound and southbound lanes on Route 29 (Morehall Road) in East Whiteland Township have fully reopened after crews completed a major phase of a $22.5 million project designed to provide long-term sinkhole remediation along Route 29 and U.S. 202 (DeKalb Pike) in Upper Merion Township.

Although traffic has resumed in both directions, additional construction activities remain underway under Stage 4 of the project. Upcoming work includes replacing a stormwater pipe near Quarry Hill Road, restoring the roadway median, and completing swale lining work along the southbound side of Route 29.

PennDOT said additional short-term traffic restrictions will be announced before the next phase begins.

As part of the remediation effort, contractors used a limited mobility grouting process to stabilize underground voids beneath the roadway. The process involved drilling holes in a grid pattern and injecting pressurized grout beneath the pavement to reduce the risk of future sinkholes.

The long-term stabilization project was launched after repeated sinkholes and emergency repairs caused ongoing traffic disruptions along both Route 29 and U.S. 202.

Drivers should remain alert for future lane restrictions and changing traffic patterns as construction continues. Plan extra time when traveling through the area and expect periodic delays during upcoming work phases.
