Completed Improvements

6/8/2011 CP1 Status: June 2011


With Cottman Avenue opened to two lanes westbound, crews are now finishing work on the south side of the roadway to complete a third lane that will carry a single lane of traffic in the eastbound direction between Torresdale Avenue and State Road in Northeast Philadelphia. Cottman Avenue is being rebuilt and widened to three lanes, two westbound and one eastbound, to improve traffic flow to and from the busy interchange. It will be converted to a two-directional roadway at the completion of work later in 2011.

Construction also is ongoing at the intersection of State Road and Princeton Avenue, where a right turn lane is being built on Princeton to accommodate traffic heading to the new State Road on-ramp to I-95 South and the east side of State Road is being widened to create an additional lane between New State Road and the ramp to I-95 North. 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.

With improvements underway at State Road and Princeton, construction 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 this summer.

Widening on the east side of State Road between Princeton and Cottman avenues is continuing. The area is scheduled to be paved shortly. This section of State Road is being widened slightly and rebuilt to provide two southbound lanes along with one northbound lane.

Paving crews have finished adjustments at streets that intersect Princeton Avenue along a five-block stretch east of Torresdale Avenue. This section of road 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.

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. Construction of the spur ramp connecting Milnor Street to the improved northbound on-ramp will begin this summer.

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.
