CONSTRUCTION LIMITED BY WEATHER
Construction activities on the first of two stages of construction to rebuild and improve the I-95 Cottman Avenue Interchange in Northeast Philadelphia were limited in January due to the weather. Sporadic construction activities may continue through the end of February as conditions permit on Cottman Avenue, State Road and at the Princeton Avenue ramp to I-95 north.
New water, sewer and gas mains are in place beneath Cottman Avenue between State Road and Torresdale Avenue. Utility contractors will complete tie-ins with sewer and water lines at cross streets, including State Road as conditions permit. Activities to finish rebuilding Cottman Avenue will resume in full-force with the arrival of moderate temperatures this spring. Cottman Avenue is being lowered and rebuilt to provide additional clearance under the Amtrak bridge and widen it to three lanes as part of the $31.9 million I-95/CP1 project that is currently 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 between Princeton and Cottman avenues, gas utility crews continue connecting gas service to the new gas main – installed as part of the widening and rebuilding that section of roadway -- to residences and business on State Road. South of Princeton Avenue, the new water main also has been tied-into the existing main at Barton Street. 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 Street.
Improvements to Princeton Avenue between Torresdale Avenue and Keystone Street have been completed. PennDOT has rebuilt this section of Princeton Avenue and installed new sub-surface utilities, traffic-calming curb extensions (bump-outs), new sidewalks and ADA (Americans with Disabilities Act) curb ramps on the five block stretch east of Torresdale Avenue. Princeton Avenue will be converted to two-ways at the finish of the CP1 project in 2011 once the existing on-ramp is removed and improvements are completed at the intersection with State Road.
East of Keystone Street, workers are expected to return this spring to widen Princeton Avenue and add a right turn lane at State Road.
Paving at the new on-ramp to southbound I-95 from State Road at Longshore Avenue also is scheduled to resume with the return of warmer weather. A retaining wall to support the I-95 embankment has been built, the stormwater drainage system for the new ramp is in place and the base paving is in place for half the width of the ramp that will funnel traffic onto I-95 south, replacing the existing southbound on-ramp from Princeton Avenue, which will be removed after the new ramp opens later in 2011.
Work also is continuing 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 second retaining wall that will support the new Milnor Street spur ramp is currently under construction.
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 in mid-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.
