SUNBURY - After approximately 25 hours, PennDOT lifted the detour of Route 147 south of here at 12:55 p.m. Thursday.

The highway was shut down and motorists rerouted because of rock slides at the Route 147-Brush Valley Road intersection. The highway was also shut down at that location from about 10 p.m. Monday to 10:20 a.m. Tuesday.

The most recent slide prompted a closure that PennDOT reported at 11:58 a.m. Wednesday. A few hours later, it was announced the highway would remain closed until Thursday afternoon and that, as an interim measure, a PennDOT crew would install jersey barrier in the area of the recent slides.

Heavy rain contributed to the situations this week.

PennDOT said it is developing a future construction project to extend the existing rock-fall fence that exists about a half-mile north of the intersection. A major rock slide in that area prompted erection of the fence in September 2007.

In February of this year, a rockslide closed both lanes of the highway at the intersection with Brush Valley Road for nearly seven hours and, fearing further trouble, a high-pressure hose from an Americus Hose Company ladder truck was used to bring down more rocks that were hanging precariously from a cliff.
