I-95 Cottman Avenue Interchange Project
Construction Update: August 2009

Construction Set to Get Underway for New State Road On-Ramp
Utility work continues on Cottman, Princeton and other surface roads

Crews have completed site clearing at State Road and Longshore Avenue and are preparing to begin construction of the new southbound on-ramp to Interstate 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. The first (I-95/CP1) of two stages of the project to improve the interchange and reconstruct the adjoining sections of I-95 (I-95/CPR) is currently under construction.

Construction of the new State Road on-ramp will have minimal impact on traffic-flow on the surface roads in the vicinity of the work area and on I-95. Construction barrier is in place along southbound I-95 at the interchange to provide a safe work area for crews to build the new ramp.

Relocation of electric and other above-ground utilities along Cottman Avenue and Old State Road, which has been underway since construction began in May, is expected to wrap up in August.  With most of the poles and lines moved, construction will begin to widen Cottman Avenue to three lanes between State Road and Torresdale Avenue.  Once crews mill the left side of Cottman Avenue, they will begin installing a new drainage system on that side of the street.

State Road also will be rebuilt to include an additional southbound lane between Cottman and Princeton  avenues.  Subsurface utility work will continue on Old State Road between Longshore Avenue and Disston Street, and new gas lines have been installed on Longshore Avenue between Old State Road and New State Road.

A new water main is in place beneath Princeton Avenue from Torresdale Avenue to State Road and another is under construction from State Road to Wissinoming Street.  New storm water inlets and fire hydrants also are under construction on Princeton Avenue.  This stretch of Princeton Avenue is being reconstructed and converted to a two-way street with intersection improvements consisting of traffic calming curb bump-outs and new sidewalks.

Demolition crews have removed structures that have been purchased for the project. Work is now underway to fill in any remaining 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, 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.

The first construction stage at Cottman Avenue, 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.
