Completed Improvements

9/7/2010 Cottman Int. Status: Sept. 2010


Water main construction is underway on State Road, where crews are excavating and installing a new 12-inch main along the northbound side of the road between Princeton and Cottman avenues.

Installation of a new 7 foot-diameter sewer main beneath Cottman Avenue west of State Road continues to progress toward completion later this month. State Road remains closed to through traffic during this operation. The closure is necessary to provide room for equipment to excavate and install the large concrete sewer piping. Through traffic is being detoured on State Road to Rhawn Street and along Torresdale Avenue back to Cottman Avenue.

In addition to installing new water, gas and sewer lines and rebuilding the roadway, PennDOT is lowering that section of Cottman Avenue slightly to provide additional clearance under the Amtrak bridge. Cottman also is being widened 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 also may take place sporadically on Cottman Avenue at State Road, and ramp construction is underway at several locations.

The northbound on-ramp at Princeton Avenue is being modified in the first phase of work to add a connecting spur from Milnor Street. 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 Milnor Street ramp is being built.

A retaining wall also is under construction for a new southbound on-ramp from State Road near Longshore Street. This new ramp will replace the existing southbound on-ramp from Princeton Avenue. Crews are installing shoring to support the existing ramp so that Princeton Avenue can be widened at the intersection with State Road.

Utility work is finished on the north side of Princeton 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, will be repaved.

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 and along the detour route along State Road, Rhawn Street and Torresdale Avenue.
  • 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.
