Completed Improvements

8/3/2011 CP1 Status: August 2011


Construction of the new southbound on-ramp from State Road at Longshore Avenue has been completed and the ramp is now opened to traffic.

With the new ramp in service, the existing southbound on-ramp from Princeton Avenue has been closed and work is under way to dismantle the structure. The ramp’s bridge over State Road has been removed, and crews will complete improvements to the Princeton Avenue/State Road intersection.

Princeton Avenue is being widened at the intersection to include two through lanes – for traffic accessing the ramp to I-95 North – as well as separate left and right turn lanes to State Road.

The five-block stretch of Princeton Avenue east of Torresdale Avenue, which was rebuilt to include traffic-calming curb extensions (bump-outs), new sidewalks, curb ramps and bicycle lanes, will be converted to two-ways at the completion of work at the State Road intersection this fall.

New paving is in place on the northbound side of State Road between Cottman Avenue and New State Road. Widening on the southbound side, where new storm water drainage is in place and new sidewalks and curbs remain under construction, is expected to finish this month.

Widening on northbound State Road between New State Road and Princeton Avenue, where it will be three lanes wide at the intersection to provide a through lane and separate left and right turn lanes onto Princeton and the northbound on-ramp, will be completed after the old Princeton Avenue southbound ramp is removed.

Southbound State Road has been rebuilt between Disston Street and the new ramp at Longshore Avenue.

Paving also has wrapped up on Cottman Avenue between State Road and Torresdale Avenue. Cottman Avenue, which has been rebuilt as a three-lane road with two lanes westbound and one lane eastbound, remains open to two lanes of westbound traffic only. It will be converted to two-ways on August 31.

Work also continues on the existing northbound on-ramp at Princeton Avenue, which is being widened to accommodate a spur ramp that will provide access to I-95 north from Milnor Street. Base paving is scheduled to be placed on the rebuilt portion of the ramp this month.

All the work is being done under the $31.9 million CP1 project, the first of two stages of construction at the I-95/Cottman Avenue Interchange in Northeast Philadelphia. Stage 2 (CP2) is scheduled to go to bid later this year and be under construction next spring.
