Completed Improvements

5/3/2011 CP1 Status: May 2011


Work is under way to improve the intersection of State Road and Princeton Avenue, where a right turn lane is being built to accommodate traffic heading to the new (under construction) on-ramp to I-95 south. The west side of the intersection has been widened and paved with the base layer of asphalt. Crews are now working on improvements on the opposite side of State Road. Once the new ramp is open, 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.

Most of the curb, sidewalk and utility work is finished on Cottman Avenue between State Road and Torresdale Avenue. Paving is expected to take place later this month. Cottman Avenue is being rebuilt and widened to three lanes, two westtbound 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.

New curbs and sidewalks are under construction on the east side of State Road between Princeton and Cottman avenues. The contractor also is currently installing the remaining storm water drainage components along the west side of State Road. This section of State Road is being widened slightly and rebuilt to provide two southbound lanes – along with one northbound lane – for access to the new ramp to I-95 south at Longshore Avenue.

Construction has resumed at that new ramp, which will replace the existing southbound I-95 on ramp on Princeton Avenue. A retaining wall to support the I-95 embankment has been built, the storm water drainage system for the new ramp is in place, and lighting and edge barrier are being place on the ramp.

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

  • Restrictions on Cottman Avenue may cause backups approaching State Road from the northbound off-ramp from I-95.
  • Restrictions on Cottman Avenue may cause backups on State Road approaching the intersection.
  • Restrictions on State Road may cause backups at the intersection with Cottman Avenue.
  • 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.
  • Construction at the intersection with Princeton Avenue may cause backups on State Road.
