TWO NEW RAMPS UNDER CONSTRUCTION ALONG WITH UTILITY WORK ON STATE ROAD, PRINCETON AVENUE
Construction crews are active at a number of locations within the Interstate 95/Cottman Avenue Interchange (I-95/CP1) work area, relocating and installing underground utilities, constructing curbs and curb ramps, and building retaining walls for two new ramps.
On Cottman Avenue, utility work (water, sewer and gas) is almost finished on the south side of the road between State Road and Torresdale Avenue. New concrete pavement has been placed on the south side between State Road and the Amtrak overpass to provide maximum pavement stability approaching the intersection with State Road (the remaining segment of Cottman Avenue will be paved with asphalt.) as utility crews finish installing curbs on the south side of Cottman west of the railroad bridge.
Cottman Avenue remains limited to a single lane west of State Road,. In addition to installing new water, gas and sewer lines and rebuilding the roadway, PennDOT is lowering that section of Cottman Avenue slightly to provide additional clearance under the Amtrak bridge. Cottman also is being 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.
Utility crews continue installing water lines on the east side of State Road between Princeton and Cottman avenues and on Cottman Avenue east of State Road. During construction in this area, on-street parking has been eliminated and the roadway is limited to one lane in each direction through the intersection with Cottman Avenue. (Parking on the southbound side will be eliminated permanently to provide room to widen the roadway.)
On Princeton Avenue, work continues to relocate a gas line on the north side of the roadway between Torresdale Avenue and State Road. New curbs and sidewalks also are being constructed at intersections along this section of Princeton Avenue. Curb “bump outs”, new sidewalk and curb at intersections, new drainage inlets and a new water main were installed on the south side of Princeton Avenue in 2009. Princeton Avenue is being converted to a two-directional roadway between (Old) State Road and Torresdale Avenue.
Work also continues on one of the 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.
The first stage of construction also has begun for the new southbound on-ramp from State Road near Longshore Avenue, where work is underway to drive piles that will support the new ramp.
- Lane restrictions on Cottman Avenue may cause backups approaching State Road from the northbound off-ramp from I-95.
- Lane restrictions on Cottman Avenue may cause backups on State Road approaching the intersection.
- Daytime lane restrictions on State Road may cause backups at the intersection with Cottman Avenue.
- Daytime lane 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.
