Completed Improvements

11/4/2010 Cottman Interchange Status: November 2010

Ramp construction also continues at State and Longshore


With all subsurface utility work completed and all traffic-calming curb extensions (bump-outs) in place, crews in early November placed the “binder” course of new pavement on Princeton Avenue east of Torresdale Avenue virtually completing improvements to the local street under the first (I95/CP1) of two stages of construction to reconstruct Interstate 95 and improve the Cottman Avenue Interchange in Northeast Philadelphia.

The “binder”, the supportive layer of thick paving, will be topped with a thin riding surface, the “wearing course”, later this month. Until then, the “binder” will provide a smooth ride for eastbound motorists – and residents – who have seen a variety of construction operations to replace and improve utilities, install curb bump-outs and ADA (Americans with Disabilities Act) curb ramps and sidewalks over the past year on the five block stretch between Torresdale Avenue and the I-95 southbound on ramp just beyond Keystone Street. Princeton Avenue will be converted to two-ways at the finish of the CP1 project in mid-2011 once the existing on-ramp is removed and improvements are completed at the intersection with State Road.

Crews installed shoring earlier this fall to support the existing southbound on-ramp at Princeton Avenue while work is underway widen Princeton Avenue and add a right turn lane at State Road. Work at that intersection is expected to continue into 2011.

Construction also is continuing this fall on the new on-ramp to southbound I-95 from State Road at Longshore Avenue. A retaining wall, to support the I-95 embankment, is in place, as is the stormwater drainage system for the new ramp. Base paving at the ramp is scheduled for this month. This new ramp will replace the existing southbound on-ramp from Princeton Avenue.

Work to improve the existing northbound on-ramp at Princeton Avenue also is progressing. A retaining wall to support the ramp’s western embankment is in place and the existing ramp is being widened so that traffic can be shifted to the left when the new spur ramp from Milnor Street is built early next year. Crews are building a second retaining wall this fall that will support the new northbound on-ramp to I-95 at Milnor Street (spur ramp). The extension from Milnor Street is being built to provide access to the interstate for the traffic on the east side of I-95.

Utility Work Continues
New water and gas mains are in place on the east side of State Road between Princeton and Cottman avenues. Crews from the city gas department (Philadelphia Gas Works) will work this fall to connect the new gas lines to residences and business on State Road. PGW also will connect mains at the intersection of Cottman Avenue and State Road this month.

Construction is nearing an end to install the new sewer main beneath Cottman Avenue between State Road and Torresdale Avenue. Completion of sewer line work will allow contractors to finish rebuilding Cottman Avenue. (Cottman Avenue was reopened to westbound through traffic in September when installation of the sewer moved west of Tulip Street.)

In addition to installing new water, gas and sewer lines and rebuilding the roadway, PennDOT is lowering that section of Cottman Avenue to provide additional clearance under the Amtrak bridge and widening it to three lanes as part of the $31.9 million I-95/CP1 project that is currently underway. The widened Cottman Avenue will be converted to a two-directional roadway to improve traffic flow to and from the busy interchange at the completion of work in mid-2011.

All the work is being done under the first of two stages of construction at the I-95/Cottman Avenue Interchange in Northeast Philadelphia. Stage 2 is expected to begin in mid-2011 at completion of the current project.

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 at State Road and Princeton Avenue may cause backups on Princeton Avenue east of Torresdale 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.
