I-95/Cottman Avenue Interchang - CP1
Cottman Avenue Half Closed for Utility Work
Ramp Construction Set to Start at Cottman Avenue Interchange
Work is underway to install a new water main and complete other sub-surface utility work beneath Cottman Avenue, restricting the roadway to a single lane between State Road and Torresdale Avenue as construction continues on the first phase (I-95/CP1) of the two-phase project to improve the interchange and rebuild adjacent areas of I-95.
- Travel Impacts
Restrictions on Cottman Avenue may cause backups approaching (Old) State Road from the northbound off-ramp from I-95. Motorists also may experience slow moving traffic and delays along (Old) State Road and Princeton Avenue weekdays during the utility work.
Cottman Avenue is being rebuilt, 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.
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.
Other phase-one utility work also is in progress on nearby sections of (Old) State Road and Princeton Avenue. New storm sewers are being installed on (Old) State Road, which is also being widened to include a second southbound lane.
By mid-month, (Old) State Road will be limited to a single lane in each direction – with no left turn lane – and parking will be prohibited, between Cottman Avenue and Barton Street (near Longshore Avenue).

Restrictions on (Old) State Road will cause backups approaching Cottman Avenue.
On Princeton Avenue, improvements to the storm water drainage system and installation of a new water main also are under construction. 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 along this stretch of road.
The foundation for the new traffic signal also is in place on New State Road at Longshore Avenue.
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 structures that have been purchased for the project and filled-in the foundations from the demolished buildings.
PennDOT also is 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. Once integrated into PennDOT’s overall Traffic Management System this fall, the cameras will be 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.
