After about 24 hours of road work, the Pennsylvania Department of Transportation has reopened southbound I-83 in southern York County.

The lanes reopened at 1:30 a.m. Sunday, according to a PennDOT news release. They had been closed since 1 a.m. Saturday because of safety concerns about the stability of the pavement, the release said.

A deteriorating drainage pipe, located in Shrewsbury Township, had created a major dip in the highway, so crews from Kinsley Construction took Saturday to repair it, according to PennDOT.

Work involved excavating the area and installing a concrete slab with steel beams encased in it to provide support for vehicles traveling over the area, the release says.

The deteriorating pipe will still need to be addressed, PennDOT says, and work will be done within the next few weeks when material for the insertion of a pipe liner becomes available.
