Motorists on Route 30 westbound in West Manchester Township might encounter delays in the area of Carlisle Avenue on Wednesday as a state Department of Transportation crew fixes a dip in the highway.
The dip is the result of a sinkhole in the area.
The paving operation will be under way between 9 a.m. and 2 p.m., said Greg Penny, PennDOT spokesman.
The two left lanes will be closed, but two lanes on the right will remain open, he said. A PennDOT crew paved the right shoulder last week to create an extra lane to prepare for the paving project.
Previous work: State officials have worked to fix the dip over the past few months.
PennDOT crews filled a "void" under the concrete pavement that was discovered in December.
Crews were following up on a stress crack that was discovered in one of the concrete slabs. The crew also noticed that the slab moved slightly when trucks drove over it.
During the investigation, workers drilled several holes into the pavement and inserted a small video camera. What the crew found was a roughly 3-foot-deep by 5- or 6-foot-wide void.
Crews filled the void with a concrete mixture as a quick repair.
The next major project planned for that portion of Route 30 is a restoration project slated to begin in 2014. It does not yet include any corrective action to the ground support of the highway.
