A busy stretch north of Middletown borough will be under construction for the next month.
PennDOT says starting Monday at 7 a.m., Vine Street will be one lane instead of two each way.
The restrictions will be between the Pennsylvania Turnpike overpass and Swatara Creek Road.
Workers will be removing guide rail in the median and replacing it with concrete curb.
It’s the start of a larger project to rehab a mile and a half of the street.
“We’ll also take advantage of the lane being out and make repairs to that dead lane there at that time too, so that will sort of move the project along when to comes to the concrete patching and the diamond grinding,” said Mike Crochunis, a spokesman for PennDOT.
About 10,000 vehicles travel this section of the road daily.
The lane restrictions are expected to last 25 days.
