A series of lane closures along Interstate 95 will begin to take effect Sunday night to allow for a multimillion-dollar overhaul of portions of the highway.

I-95 north will at 10 p.m. be reduced to two lanes between the Bridge Street and Cottman Avenue interchanges to accommodate construction in the median area, according to PennDOT.

The closure will last until 5 a.m. Monday and will persist each night through next Saturday, March 21.

I-95 south will be reduced to one lane between Palmer and Shackamaxon streets, just south of the Girard Avenue Interchange, from 10 p.m. Monday to 5 a.m. Tuesday, as the new concrete pavement undergoes routine testing.

Next Friday night through Saturday, I-95 north will be down to one through lane approaching the Girard Avenue Interchange, as crews erect beams for the center section of the I-95 bridge over Columbia Avenue.

Motorists are advised to expect slow-moving traffic and delays as they enter work zones.

The construction comes as part of a series of ongoing projects, currently being completed under contracts totaling more than $251 million, to rebuild the Girard and Cottman Avenue interchanges, as well as adjoining sections of I-95.
