At 6 p.m. Friday, PennDOT District 8 will close the right lane and shoulder of Interstate 83 South in Shrewsbury Township, just north of the Pennsylvania State Line, to temporarily repair a metal culvert under the roadway.

There is a dip in the pavement, according to PennDOT.

The southbound lanes of I-83 will be restricted to a single lane, approximately 1.2 miles north of the Pennsylvania/Maryland State Line from Friday through early evening Sunday.

PennDOT advises motorists to be alert for this weekend operation, to obey work zone signs and to slow down when traveling through the work zone for their safety and for the safety of the road crews.
