Completed Improvements

3/19/2010 Cottman Interchange Status 3.19.10


Following a winter where weather conditions limited the progress of construction on the first stage of work to improve I-95 and the Cottman Avenue Interchange (I-95/CP1), utility work beneath the closed half of Cottman Avenue has resumed along with work on the retaining wall alongside on-ramp to I-95 north.

Water line construction is expected to wrap up beneath the southern half of Cottman Avenue, which remains limited to a single lane west of State Road, this month. 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 and 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.

As utility work under Cottman Avenue is being finished, crews will begin utility construction and installation of new storm water inlets on State Road between New State Road and Cottman Avenue. When construction moves to State Road, crews will close half of the roadway to traffic, limiting capacity to one lane in each direction and eliminating the left turn lane to Cottman Avenue. On-street parking on State Road also will be limited in the work area. (Parking on the southbound side will be eliminated permanently to provide room to widen the roadway.)

Also this spring, work to install a new gas line and construct new curbs and sidewalks will get underway on the northern half of Princeton Avenue east of Torresdale Avenue. Most of the planned improvements to the southern side of Princeton Avenue -- curb “bump outs”, new drainage inlets and a new water main -- are in place. (Curb ramps will be installed this spring.) Like Cottman Avenue, Princeton Avenue is being converted to a two-directional roadway between (Old) State Road and Torresdale Avenue.

Construction has resumed on one of the two 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 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.
