Although nowhere near as big as the landslide that ended hopes of a Super WalMart in Kilbuck Township a few years ago, the crumbling hillside along Route 65 in the same vicinity has once again closed the highway to traffic.

Relatively minor levels of rocks and mud came onto the northbound lanes in Glenfield on Wednesday, about a quarter mile north of the I-79 interchange. PennDOT officials closed all four lanes of traffic to clear the area and assess the danger, but southbound lanes were reopened to traffic later that day.

While the roadway is now clear, experts remain concerned about movement of the adjacent hillside. According to PennDOT, the southbound lanes could remain closed throughout the weekend while debris is removed from the hillside.

Drivers can detour to I-79 South, to northbound Route 51, to the Sewickley Bridge and back onto southbound Route 65.
