PennDOT contractors will begin repairing and resurfacing more than eight miles of Route 30 in western Lancaster County on Sunday night.
While there will be no daytime restrictions, motorists may encounter single-lane traffic restrictions in one or both directions between 9 p.m. and 6 a.m.
Motorists may also encounter closed ramps and detours at the interchanges with Third Street, Prospect Avenue, Stony Battery Road or Centerville Road during the work.
Pennsy Supply Inc. of Annville, Lebanon County, has been awarded the roughly $7 million contract.
The project includes repairing the road base, removing old asphalt and repaving the road from the Susquehanna River and Prospect Road and the rest of road to Marietta Avenue will have work done to seal and help extend the life of the pavement.
Work normally will run Sunday through Thursday nights, with Friday as a make-up night should they lose a night to inclement weather.
The project is scheduled to finish in late October. Nearly 23,000 vehicles use the road daily.
