KING OF PRUSSIA — A majority of roadway impacted by several sinkholes on U.S. Route 202 in King of Prussia reopened early Tuesday, per Pennsylvania transportation officials.
The series of sinkholes have forced the closure of a stretch of the major thoroughfare for nearly one week in Upper Merion Township, but transportation officials said that both northbound lanes and the left southbound lane have reopened to traffic following “following asphalt paving operations.”
The closure still stands for the right southbound lane of U.S. Route 202, also known as Dekalb Pike, between Saulin Boulevard and Henderson Road, according to transportation officials. A roughly 10-by-12-foot sinkhole, discovered sometime late Wednesday night into Thursday morning, shut down the northbound lanes.
The closure was extended following complications found during the repair process, according to PennDOT Deputy Communication Director Brad Rudolph.
The other sinkholes, situated in both southbound lanes, were attended to over the weekend.
A “water service lateral” was found in the area’s “largest sinkhole,” Rudolph said. It was filled with flowable fill, tested “and found to have no leaks.” The other sinkhole was approximately 6 feet deep.
“This hole contained an active water service line, which due to the concern of settlement affecting the line, was backfilled as well,” Rudolph said in a statement late Sunday.
It still needs to be filled up to sub-grade elevation, he said.
Rudolph added that once flowable fill is applied, it will need 24 hours to settle before accelerated concrete is installed. It’s unclear when the final lane will reopen.
