Completed Improvements

7/5/2011 CP1 Status: July 2011


Construction continues on two on-ramps along with work on Cottman Avenue, State Road and the intersection of State Road and Princeton Avenue as the first (I-95/CP1) of two phases of work to rebuild I-95 at the Cottman Avenue Interchange heads for completion this fall.

Widening is under way on State Road approaching Princeton Avenue to provide a northbound right-turn lane to the I-95 North on ramp. Construction to add a lane on Princeton Avenue also is ongoing on both sides of the intersection. A new right turn lane is being built on Princeton to accommodate traffic heading to the new State Road on-ramp to I-95 South at Longshore Avenue. Once the new ramp is opened later this year, the existing southbound Princeton Avenue on-ramp will be removed, including the bridge carrying the ramp over State Road, and improvements at the intersection will be completed.

Base paving has been placed on the widened segment of State Road south of Princeton Avenue. Placement of the final paving layer, the wearing course, will be completed on the entire widened section on the east side of State Road from south of Princeton to Cottman Avenue will be completed in August.

Construction also continues on the new southbound ramp from State Road at Longshore Avenue. Crews will place the remaining ramp concrete, pave the ramp shoulder and begin work to tie-in the new ramp with I-95 south in July. Work will begin later this month on the foundation for a large overhead sign for the new ramp on State Road.

A five-block stretch of Princeton Avenue east of Torresdale Avenue was rebuilt and new sub-surface utilities, traffic-calming curb extensions (bump-outs), new sidewalks and curb ramps were installed in 2010. Princeton Avenue will be converted to two-ways at the finish of the CP1 project in 2011 after the existing on-ramp is removed and improvements are completed at the intersection with State Road.

Paving on the south side of Cottman Avenue is finished. Paving at the intersection of Cottman and Torresdale avenues is expcted to be done in July.  Cottman Avenue has been opened to two lanes of westbound traffic as crews finish line painting and installing signs for a third lane that will carry a single lane of traffic in the eastbound direction between Torresdale Avenue and State Road . Cottman Avenue will be converted to a two-directional roadway, with two westbound and one eastbound, at the completion of CP1.

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. A retaining wall is in place to support the embankment between the existing northbound off-ramp and the improvements that are under way to the adjacent on-ramp.

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 begin later this year.

Travel Impacts

  • Off-peak restrictions on Cottman Avenue;
  • Off-peak restrictions on State Road;
  • Construction of the new State Road southbound on-ramp, and the new Milnor Street access ramp northbound, will have minimal impact on traffic-flow on I-95.
