After four years of construction, four lanes are now open in both directions on Interstate 95 in Northeast Philadelphia.

The $212 million road-widening and reconstruction project, which started in 2012, wrapped up late Wednesday night, PennDot said.

Motorists now have four lanes of traffic between the Cottman Avenue and Bridge Street interchanges.

In the past few days, lines were painted, barriers removed and safety rumble strips were installed, bringing a long-awaited end to the roadwork that has often snarled traffic on the busy interstate.

The project widened and rebuilt 1.4 miles of I-95 between Beligh Avenue and Levick Street. Other work done included repairing structurally deficient bridges, upgrading ramps, constructing retaining walls and installing storm water drainage pipes.

More work on the interstate is ahead, however. Next year, crews will finish up work to extend Princeton Avenue to Milnor Street, rebuild New State Road and install a storm drainage pipe along Bleigh Avenue, PennDot said.

Construction work is also continuing on 95 north of Center City, at the Girard Avenue and Betsy Ross Bridge interchanges.
