Barriers have been set up along Route 30 in Lancaster County as a major road project gets under way.
Route 441 is being relocated from going through downtown Columbia to a new path along the Susquehanna River.
The $20.4 million project includes a bridge that will be built to carry traffic over Route 30.
That work will cause lane closures at night sometime next year, said Mike Crochunis, a spokesman for the Pennsylvania Department of Transportation.
Traffic would also be stopped for about 15 minutes at a time while workers set the bridge beams.
"That's would be the extent of traffic interruptions on Route 30," Crochunis said.
The project is slated to be finished by the end of next year.
