Sinkhole shuts down stretch of Route 202 again near King of Prussia Mall
Progress made on sinkhole disrupting stretch of Route 202 near King of Prussia Mall
FOX 29's Hank Flynn reports PennDOT is waiting for temperatures to warm Friday before they can use a flowable fill method mixing concrete with water to fill the holes to hopefully have the road back open this weekend.
UPPER MERION TOWNSHIP, Pa. - Drivers beware! Parts of a busy highway near King of Prussia have been shut down yet again.
Route 202 is closed northbound between Henderson Road and Saulin Boulevard in Upper Merion Township due to "pavement failure."
On Wednesday afternoon Pennsylvania American Water said the business Rossi Auto Salvage reported pressure issues.
Crews responded by opening up the road to find a leaking pipe and to their surprise, a void under the area.
The same stretch of road was shutdown twice this past July for sinkhole repairs.
Harold Windisch, Assistant District Executive for Construction, PennDOT District 6 says King of Prussia has had issue with the erosion of limestone.
"When water hits limestone it erodes the limestone and that’s what happened here. We got some water in here and it opened up a little bit," said Windisch.

Stretch of Route 202 shut down again after sink hole repairs fail: officials
Portions of Route 202 are closed to traffic between Henderson Road and Saulin Boulevard in Upper Merion Township a week after the same stretch of road was shut down.
Drivers should use Henderson Road and Saulin Boulevard as crews survey the area.
PennDOT plans on using radar technology to see if more holes exist in the ground and if further aggressive restoration is needed.
The Department of Transportation workers are waiting for temperatures to warm Friday before they can use a flowable fill method mixing concrete with water to fill the holes. PennDOT sources tell FOX 29’s Hank Flynn they aim to have the hole filled and the portion of that road back open by sometime this weekend.
