CONSTRUCTION RESUMES ON COTTMAN AVENUE, STATE ROAD, TWO RAMPS
Construction has resumed on the first of two stages of the project to rebuild and improve the I-95 Cottman Avenue Interchange in Northeast Philadelphia, where the focus this spring will be on completing work on Cottman Avenue and State Road and resuming work on two ramps.
On Cottman Avenue, crews have completed utility work and installed storm water drainage and are building curbs and sidewalks along the north side and installing new signals. Paving is expected to resume in April. Cottman Avenue is being lowered and rebuilt to provide additional clearance under the Amtrak bridge and to widen it to three lanes as part of the $31.9 million I-95/CP1 project that is underway. The widened Cottman Avenue will be converted to a two-directional roadway to improve traffic flow to and from the busy interchange at the completion of work in mid-2011.
On the east side of State Road from south of the I-95 overpass to Cottman Avenue, gas utility crews have finished connecting businesses and residences to the new gas main – installed as part of the widening and rebuilding on that section of roadway – and will work to install new sidewalks.
The contractor also will install storm water drainage components along the west side of State Road this spring along with new signals, and then pave the improved roadway. This section of State Road is being widened slightly and rebuilt to provide two southbound lanes for access to the new southbound ramp at Longshore Avenue.
With improvements to Princeton Avenue between Torresdale Avenue and Keystone Street mostly completed (adjustments at cross streets will be done this spring), work is set to get underway at the intersection with State Road. Princeton Avenue is being widened to provide a separate right-turn lane onto State Road for access to the new southbound on-ramp that is under construction at Longshore Avenue. The existing on-ramp to southbound I-95 at Princeton Avenue will be removed when the new ramp is in service and all improvements are in place on Princeton Avenue later this year.
A five-block stretch of Princeton Avenue east of Torresdale Avenue was rebuilt and new sub-surface utilities, traffic-calming curb extensions (bump-outs), new sidewalks and ADA (Americans with Disabilities Act) curb ramps were installed in 2010. Princeton Avenue will be converted to two-ways at the finish of the CP1 project in 2011 after the existing on-ramp is removed and improvements are completed at the intersection with State Road.
Construction of the new on-ramp to southbound I-95 from State Road at Longshore Avenue also is underway. A retaining wall to support the I-95 embankment has been built, the storm water drainage system for the new ramp is in place and paving has begun.
And work also has resumed on the existing northbound on-ramp at Princeton Avenue, which is being widened to accommodate a spur ramp that will provide access to I-95 north from Milnor Street. A retaining wall that will support the embankment for the new Milnor Street spur ramp is currently under construction. The spur ramp will be built this summer once the retaining wall is in place.
All the work is being done under the first of two stages of construction at the I-95/Cottman Avenue Interchange in Northeast Philadelphia. Stage 2 is expected to begin later in 2011 at completion of the current project.
- 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 State Road may cause backups at the intersection with Cottman 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.
- Construction at the intersection with Princeton Avenue may cause backups on State Road.
