Maintenance crews are making repairs this week to the inside shoulder of southbound Interstate 81 between Exit 77 for Manada Hill and Hershey and Exit 72 for Paxtonia and Linglestown, according to PennDOT.
The left lane of I-81 South will be closed between 9 a.m. and 2 p.m., Monday through Thursday, so that the crews can do their work safely.
Instead of two lanes available to traffic, the work will restrict southbound motorists to a single lane through the work area.
Significant traffic backups may occur.
Drivers are urged to be alert and to slow down when approaching and traveling through the work zone.
