Completed Improvements

12/11/2009 Cottman Interchange Status:12.11.09

Water Main Construction Continues on Cottman Avenue Between State Road and Torresdale Avenue

Crews continue installation of a new water line and a storm water drainage system beneath Cottman Avenue between State Road and Torresdale Avenue. PennDOT’s contractor has installed and tested the new main and is now working to install the remaining drainage inlets beneath the closed section of Cottman Avenue.

Cottman Avenue remains limited to a single lane west of State Road, with the southern half of the roadway closed for excavation and reconstruction. 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 tie-in the new water main to the main beneath State Road, and then begin utility construction and installation of new inlets on State Road, between New State Road and Cottman Avenue, early next year. When construction moves to State Road, crews will close half of the roadway to traffic and eliminate on-street parking in the work area. (Parking on the southbound side will be eliminated permanently to provide room to widen the roadway.)

State Road will be limited to a single lane in each direction – with no left turn lane – during this stage of construction.

Half of State Road between the split at New State Road and Longshore Avenue has been reconstructed. Crews are now rebuilding the opposite half and installing new curb and sidewalk. This section of road is being rebuilt to service the new on-ramp to I-95 north at Longshore Avenue that will be constructed beginning in 2010.

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

On Princeton Avenue east of Torresdale, most of the new inlets are in place, along with a new water main. New sidewalks, signals and curb “bump outs” are in place at most intersections on the south side of Princeton as well. Work to install a new gas line could begin this winter, with construction of new curbs and sidewalks on  the north side expected to begin next spring.

Like Cottman Avenue, Princeton Avenue is being converted to a two-directional roadway between (Old) State Road and Torresdale Avenue.

Construction also is expected to begin by year’s end on a retaining wall 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

  • 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 the interchange and adjoining sections of I-95 is scheduled to begin in 2011.
