Completed Improvements

11/18/2009 Cottman Interchange Status: 11.18.09

Utility Work Continues on Cottman, Princeton Avenues

Construction continues on Cottman Avenue to install new water main and other sub-surface utilities between State Road and Torresdale Avenue.

Cottman Avenue remains limited to a single lane west of State Road, with the southern half of the roadway closed for excavation. This stretch of road is being lowered slightly to provide additional clearance under the Amtrak bridge. It also is being 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.

Crews expect to begin utility construction and installation of new inlets on State Road, between New State Road and Cottman Avenue, by the end of the month. When construction moves to State Road, half of the roadway will be  closed to traffic, limiting the roadway to one lane in each direction with no left turn lanes,  and  on-street parking will be temporarily eliminated in the work area.

Half of another section of State Road, between New State Road and Longshore Avenue, has been reconstructed (see left photo). Crews have begun rebuilding the opposite half.  A short detour is in place for all traffic at this location.

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


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 closed 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.

Most of the new inlets are in place along with 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.

Most of the traffic calming curb bump-outs are in place, and new sidewalks remain to be constructed at intersections along this stretch of road (see right photo).  New signals also will be installed at signalized intersections along this stretch of Princeton.

Crews have completed site clearing at State Road and Longshore Avenue in preparation for construction to begin late this year or early in 2010 on 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.

Work also continues on a new access ramp from Milnor Street to tie-in to the existing northbound on-ramp from Princeton Avenue. Crews there are scheduled to construct retaining walls beginning this fall to support the existing ramp during construction of the new access ramp.

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.

PennDOT also 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 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.
