Construction Update

Utility Work Continues on Cottman, Princeton Avenues

As construction continues on Cottman Avenue to install a new water main and other sub-surface utilities between State Road and Torresdale Avenue, crews expect to begin similar utility construction on State Road by the end of the month. Cottman Avenue remains limited to a single lane west of State Road, with the southern half of the roadway closed for excavation. That excavation is expected to move a short distance to the west side of Torresdale Avenue in the second half of October.

When construction moves to State Road,  between New State Road and Cottman Avenue, crews will close half of the roadway to traffic and temporarily eliminate on-street parking in the work area. State Road will be limited to a single lane in each direction – with no left turn lane – during this stage of construction.

Utility construction also is progressing on State Road between New State Road and Longshore Avenue. A short detour is in place for southbound traffic at this location.


 Travel Impacts

  • Restrictions on Cottman Avenue may cause backups approaching State Road from the northbound off-ramp from I-95.
  • Restrictions on State Road will cause backups approaching Cottman Avenue.
  • State Road is reduced to a one way road between New State Road and Longshore Avenue.
  • Restrictions on Princeton Avenue may cause slow moving traffic on Princeton and delays on Torresdale Avenue at the intersection with Princeton Avenue.

Both Cottman Avenue and State Road are being rebuilt to improve traffic movement at the revamped interchange.

Cottman Avenue is being lowered slightly to provide additional clearance under the Amtrak bridge and widened 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.

State Road is being reconstructed to provide two lanes southbound and one northbound.

Work also is underway to construct an access ramp from Milnor Street to tie-in to the existing northbound on-ramp from Princeton Avenue. Crews have placed temporary pavement, set concrete barrier and shifted Princeton Avenue on-ramp traffic to provide a safe working area during construction. Retaining walls are being built to support the existing ramp during construction of the new access ramp.

Work continues on improvements to the storm water drainage system and installation of a new water main on Princeton Avenue east of Torresdale Avenue. Like Cottman Avenue, Princeton Avenue is being converted to a two-directional roadway between (Old) State Road and Torresdale Avenue. Traffic calming curb bump-outs and new sidewalks also are being installed at intersections along this stretch of road.

Crews have completed site clearing at State Road and Longshore Avenue in preparation for construction this fall of the new southbound on-ramp to I-95.  The new ramp, which will replace the existing southbound access from Princeton Avenue, is a major component of the ongoing reconstruction of I-95 and the Cottman Avenue Interchange.

 Travel Impacts

  •  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.

Demolition crews have removed most of the other structures that have been purchased for the project and filled-in the foundations from the demolished buildings.

PennDOT also has installing 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 Traffic Management Center in King of Prussia to keep traffic moving through the area and to enable PennDOT to quickly 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 he interchange and adjoining sections of I-95 is scheduled to begin in 2011.
