Completed Improvements

8/3/2010 Cottman Interchange Status 8.3.10

SEWER LINE, RAMPS UNDER CONSTRUCTION AT COTTMAN AVENUE INTERCHANGE

Installation of a 7 foot-diameter sewer main beneath Cottman Avenue continues to progress toward Tulip Street, and ramp construction remains underway at two locations under the first stage of the Interstate 95/Cottman Avenue Interchange improvement project in Northeast Philadelphia.

Sewer main work has closed Cottman Avenue to through traffic between State Road and Tulip Street. (The road remains open to local traffic up to the Amrtrak overpass near Keystone Street.) Construction on the new main, along with completion of other subsurface utility work (water, gas, Verizon) beneath Cottman Avenue and reconstruction of the south side of the road – including new curb and sidewalk – will continue through the remainder of the summer.

The closure is necessary to provide room for equipment to excavate and install the large concrete sewer piping. Through traffic is being detoured on State Road to Rhawn Street and along Torresdale Avenue back to Cottman Avenue.

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 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. Utility work also may take place sporadically on Cottman Avenue east of State Road.

Work is set to start on installation of 12-inch water main under State Road between Princeton and Cottman avenues. On-street parking has been eliminated and the roadway is limited to one lane in each direction through the intersection with Cottman Avenue. New curb and sidewalk have been installed on (New) State Road at Disston Street and Longshore Avenue.

On Princeton Avenue, pile driving and installation of shoring is scheduled at the existing on-ramp to I-95 South. The shoring will support the ramp embankment so that Princeton Avenue can be widened in that area.

Utility work is finished on the north side of Princeton Avenue between Torresdale Avenue and State Road. Curb and sidewalk construction also are being completed on both sides of the roadway. (Curb “bump outs” and other improvements were completed on the south side of Princeton Avenue in 2009. The remaining sidewalk will be rebuilt this summer.) Princeton Avenue will be converted to a two-directional roadway between (Old) State Road and Torresdale Avenue at the completion of CP1 in mid-2011.

The retaining wall along the ramp from Princeton Avenue to I-95 north is nearly finished. The wall that will support the existing on-ramp during work to modify the ramp to provide new access from Milnor Street.  A retaining wall remains under construction at the new southbound on-ramp from State Road at Longshore Avenue. Shoring to support the I-95 embankment is in place and work is now underway on the retaining wall at that location.

Travel Impacts

  • 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 and along the detour route along State Road, Rhawn Street and Torresdale Avenue.
  • Restrictions on State Road may cause backups at the intersection with Cottman Avenue.
  • 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.

Construction of I-95/CP1 is expected to be completed in mid- 2011. Stage 2 reconstruction of the interchange and adjoining sections of I-95 is scheduled to begin in 2011.
