ACTIVITIES AT SEVERAL CONSTRUCTION AREAS AT COTTMAN INTERCHANGE
Construction is progressing in several key areas on the $31.9 million CP1 project to completed the first of two stages of rebuilding and improve the I-95 Cottman Avenue Interchange in Northeast Philadelphia.
Curb and sidewalk improvements are being completed this spring on the east side of State Road between Wellington Street and Cottman Avenue. The area will be paved this spring. The contractor also is currently installing storm water drainage components along the west side of State Road in the same area. This section of State Road is being widened slightly and rebuilt to provide two southbound lanes – along with one northbound lane – for access to the new southbound ramp at Longshore Avenue.
Construction has resumed at that new ramp, which will replace the existing southbound I-95 on ramp on Princeton Avenue. 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 construction of the new ramp pavement has resumed.
Work also is continuing this spring to improve the intersection of State Road and Princeton Avenue, where a right turn lane is being built to accommodate traffic heading to the new State Road on-ramp. Once the new ramp is open, the existing southbound Princeton Avenue on-ramp will be removed, including the bridge carrying the ramp over State Road.
Paving crews have returned to complete pavement adjustments at streets that intersect Princeton Avenue along a five-block stretch east of Torresdale Avenue. This section of road was rebuilt and new sub-surface utilities, traffic-calming curb extensions (bump-outs), new sidewalks and 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.
Work also continues 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 is in place to support the embankment between the existing northbound off-ramp and the improvements that are under way to the adjacent on-ramp. Construction of the spur ramp connecting Milnor Street to the improved northbound on-ramp will begin this summer.
And crews on Cottman Avenue are finishing drainage, curbs and sidewalks along the north side and are getting set to pave the rebuilt section of road this spring. Protective fencing is currently being installed between the roadway and sidewalk on Cottman Avenue beneath the Amtrak overpass.
Cottman Avenue is being rebuilt and widened to three lanes, two eastbound and one westbound, to improve traffic flow to and from the busy interchange. It will be converted to a two-directional roadway at the completion of work later in 2011.
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.
