Motorists on I-95 in Philadelphia will get an additional obstacle starting Monday.

The Pennsylvania Department of Transportation will start a 30-month, $160 million project to rebuild ramps and improve connections at the confluence of I-95, the Betsy Ross Bridge, and Aramingo Avenue.

The project is the first of three in the works to improve the interchange and to widen and reconstruct I-95 and its bridges between Wheatsheaf Lane and Margaret Street. The work will mean intermittent lane closures on northbound I-95 and on Aramingo Avenue.

In 2016 and 2017, the southbound I-95 off-ramp to Aramingo Avenue will be closed for 5½ months and the Aramingo Avenue on-ramp to southbound I-95 will be closed for 8½ months.

The project is scheduled to be completed in the fall of 2017.

Driscoll Construction Co. of Blue Bell and Richard E. Pierson Construction Co. of Woodstown, N.J., are the general contractors. The project, part of a decadelong rebuilding of I-95, is being paid for with federal funds, PennDot said.
