Completed Improvements

6/29/2010 Cottman Interchange Status 6.29.10


Utility work continues on several surface roads and ramp construction is underway at two locations as the first stage of the Interstate 95/Cottman Avenue Interchange improvement project in Northeast Philadelphia heads into the busy days of summer.

Crews have begun installation of a 7’-diameter sewer main beneath a section of Cottman Avenue west of State Road. Construction on the new main, along with completion of other subsurface utility work (water, gas) beneath Cottman, will continue through the summer months. Cottman Avenue is closed to through traffic between the Amtrak overpass and Tulip Street to provide room for equipment to excavate and install the new concrete piping.

The intersecting side streets remain open to local traffic, providing access to businesses located on Cottman Avenue. 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 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.

Much of the utility work has been completed on the south side of Cottman Avenue, and crews are placing new pavement on the south side of Cottman between State Road and Tulip Street.

Utility crews continue installing water service on the east side of State Road between Princeton and Cottman avenues and finishing construction of curb and sidewalk on State Road at Disston Street and Longshore Avenue. During construction in this area, on-street parking has been eliminated and the roadway is limited to one lane in each direction through the intersection with Cottman Avenue. (Parking on the southbound side will be eliminated permanently to provide room to widen the roadway.) Utility work also may take place sporadically on Cottman Avenue east of State Road.

On Princeton Avenue, gas line installation is finished on the north side of the roadway between Torresdale Avenue and State Road. New curbs and sidewalks also are being constructed at intersections along this section of Princeton Avenue. Curb “bump outs”, new sidewalk, curbing and signals at intersections, new drainage inlets and a new water main were installed on the south side of Princeton Avenue in 2009. Princeton Avenue will be converted to a two-directional roadway between (Old) State Road and Torresdale Avenue.

Retaining wall construction continues at two ramp locations as well. Much of the wall that will support the existing on-ramp to I-95 north during work to modify the ramp is in place. PennDOT will build a new access ramp from Milnor Street that will tie-in to the existing northbound on-ramp from Princeton Avenue.

A retaining wall also is under construction to support the I-95 embankment for a new southbound on-ramp from State Road near Longshore Avenue. Construction of the new ramp is expected to begin later this summer.

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.
  • Restrictions on Princeton Avenue may cause slow moving traffic on Princeton and delays on Torresdale Avenue at the intersection with Princeton 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.

PennDOT has installed a series of traffic cameras along Torresdale Avenue, State Road, and a select number of other major intersections to monitor traffic flow and identify incidents in the vicinity of the construction area. The cameras are being monitored at PennDOT's regional Traffic Management Center, where personnel can dispatch crews and equipment to incidents occurring in the work area.

Construction of I-95/CP1 is expected to be completed in May 2011. Stage 2 reconstruction of the interchange and adjoining sections of I-95 is scheduled to begin in 2011.
