The ramp from North Hills Road onto I-83 north will close for construction for up to a week starting Monday.
During the closure, crews will widen the entrance to the ramp, said Mike Crochunis, spokesman for the state Department of Transportation.
The work is part of a larger $2.5 million project to widen North Hills Road, he added.
Drivers looking to use that ramp will be directed north to Route 30, where they can turn left and then take a ramp onto I-83 north.
Next ramp: The next part of the project will involve the ramp coming off of I-83 north that ends in an intersection with Market Street; North Hill Road begins across the intersection from the end of the ramp, Crochunis said. That ramp will close for a weekend later in August or in September.
Workers will widen the end of that ramp, which now includes a left-turn lane, a right-turn lane and a lane that goes straight onto North Hills Road. The widening will add another lane going straight, Crochunis said.
Future work will do much the same to North Hills Road at the ramp closing Monday. The northbound portion of the road consists of a left-turn lane onto the ramp and a lane going straight toward Route 30. The project will add another lane of traffic going straight, Crochunis said.
Other ramps might have temporary closings over the course of the project, which will wrap up September 2015, he said.
J.D. Eckman of Atglen, Pa., was awarded the contract from PennDOT.
North Hills Road handles 24,000 cars per day, Crochunis said.
