Completed Improvements

4/22/2010 Cottman Interchange Status 4.22.10


Utility work related to the first stage of construction to improve the Interstate 95/Cottman Avenue Interchange has expanded to include a segment of State Road as well as the north side of Princeton Avenue.

Crews are installing new storm water inlets on the east side of State Road between Cottman and Princeton avenues. 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.)

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

Water line relocation on the south side of Cottman Avenue has wrapped up and crews are working to finish construction of curbing on the south side prior to reconstructinh that half of the roadway between State Road and Torresdale Avenue. Cottman Avenue remains limited to a single lane west of State Road. In addition to installing new water, gas and sewer lines, PennDOT is lowering that section of Cottman Avenue slightly to provide additional clearance under the Amtrak bridge. Cottman also is being widened it to three lanes as part of the $31.9 million I-95/CP1 project. The widened Cottman Avenue will be converted to a two-directional roadway to improve traffic flow to and from the busy interchange.

Construction also is progressing on one of the two retaining walls that will support the existing on-ramp to I-95 north during work to modify the ramp to include a new access ramp from Milnor Street. The Milnor Street access will tie-in to the existing northbound on-ramp from Princeton Avenue. 

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.
  • 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.
