Construction crews on Monday will begin work on a nearly seven-mile stretch of Route 234 between East Berlin and York.
The crews will prepare the roadway for paving between the intersection with Sunset Road in Paradise Township to the intersection with Route 462, according to PennDOT spokesman Mike Crochunis.
Those who travel Route 234 west of York between Monday and mid-December may encounter single-lane traffic restrictions on weekdays after 8:30 a.m., Crochunis said.
The roadway will be resurfaced next year, and construction crews in the spring will close a section of Route 234 for a weekend to replace a 54-inch drainage cross-pipe.
The paving project is due to be completed by the end of September 2014.
