Completed Improvements

10/1/2010 Cottman Int. Status: Oct. 2010

Utility installation continues along State Road, Cottman Avenue

Construction is progressing on the new southbound on-ramp from State Road and on the expansion of the northbound on-ramp from Princeton Avenue under the first of two stages of improvements to I-95 and the Cottman Avenue Interchange in Northeast Philadelphia.

With the retaining wall in place to support the embankment, crews continue excavation to establish the grade and are installing storm water drainage components for the new southbound on-ramp from State Road near Longshore Avenue. This new ramp will replace the existing southbound on-ramp from Princeton Avenue. The old ramp will be removed once the new ramp is in operation, which is expected in 2011.

Crews at the existing southbound on-ramp at Princeton Avenue have installed shoring to support the ramp while Princeton Avenue is widened at the intersection with State Road. Construction to widen the intersection of Princeton Avenue and State Road to include a right turn lane for traffic heading to the new ramp is expected to continue into 2011.

Work also continues on the northbound on-ramp at Princeton Avenue. 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 will build a second retaining wall this fall that will support the new Milnor Street ramp. The extension from Milnor Street will provide access to the interstate for the traffic on the east side of I-95.

Utility Work Continues
Water main construction on State Road between Princeton and Cottman avenues, where crews have installed a new 12-inch main along the east side of the road, has finished. Crews will work this fall to connect businesses and residences to the new main. In addition to work on the water service, PGW workers are now installing a new six-inch gas main beneath that same stretch of State Road.

The new 84-inch diameter sewer main is in place beneath Cottman Avenue between State Road and Tulip Street. Work is expected to resume this fall to excavate and install a smaller extension (54-inch diamer) of the main beneath Cottman from Tulip Street to Hegerman Street.  (Cottman Avenue was reopened to 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.

Utility work is finished on the north side of Princeton Avenue between Torresdale Avenue and State Road. New curb and sidewalk also have been completed on both sides of the roadway. (Curb “bump outs” and other improvements were completed on the south side of Princeton Avenue in 2009.) Princeton Avenue, which will be converted to a two-directional roadway between (Old) State Road and Torresdale Avenue at the completion of CP1 in mid-2011, is scheduled to be repaved this month.

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.
