A portion of the the westbound lanes of Route 30 in Hellam Township reopened Sunday night after crews fixed area of the highway plagued by sinkholes.

Repair work included excavating a 15-foot deep, 85-foot long portion of the highway near the Shoe House Road overpass, according to a news release from the state Department of Transportation.

Crews closed the westbound lanes Friday night and reopened it at 7:45 p.m. Sunday, PennDOT said.

The work is part of a $3.4 million project to repair and resurface a roughly 4-mile stretch of Route 30 from North Hills Road in Springettsbury Township to the area of the sinkhole.

Kinsley Construction was contracted to take on the work, which includes sinkhole and base repair, line painting, new signs, milling and resurfacing, the release says.

Now that the sinkhole is repaired, crews will change to working nightly from 8 p.m. to 6 a.m., the release says.

The project is expected to be finished in September 2015.
