    PENNDOT COMPLETES SECOND CONTRACT TO IMPROVE I-95/COTTMAN AVENUE INTERCHANGE

    January 2018 — Work has been substantially completed on a $212.3 million in improvements to Interstate 95 at the Cottman Avenue (Route 73) Interchange.


    Under construction since late 2012, the project, Section CP2, rebuilt and widened northbound and southbound I-95 to include a fourth lane in each direction from just north of Bleigh Avenue, at the interchange, to Levick Street, just north of the Bridge Street exit.

    In addition, mainline I-95 bridges over Bleigh, Cottman, Princeton, Longshore, Magee and Unruh avenues and New State Road were widened and rebuilt, as were the northbound  on- and off-ramps at Cottman Avenue and Princeton Avenue, and the southbound off-ramp at Bleigh Avenue.

    Improvements also were completed on surface streets under each of the bridges, including installation of sidewalks, pedestrian-friendly LED lighting, and stamped-concrete abutment walls depicting icons of the industrial heritage of adjoining neighborhoods. The surface street improvements were guided by the I-95 Sustainable Actions Committee, which held community meetings during the design phase of the project to develop “quality of life” improvements that were included in the construction contracts.

    Also under the Section CP2 contract,n14 retaining walls were built to support northbound and southbound widening; eastbound Princeton Avenue was extended from State Road to Milnor Street; and State Road/New State Road was widened to four lanes between Princeton Avenue and Milnor Street.

    Segments of an 84”-diameter water main and 126” sewer main were replaced along the west side of the interstate between Bleigh and Princeton avenues.

    Section CP2 construction followed the completion of improvements to the interchange area under the initial, $34 million Section CP1 contract that were built between 2009 and 2012. Among Section CP1 improvements were:

    • Installation of traffic-calming features along Princeton Avenue between Torresdale Avenue and State Road and conversion of Princeton Avenue from a one-way to two-ways;
    • Removal of the old southbound on-ramp from Princeton Avenue and construction of a new replacement ramp to southbound I-95 at Longshore Street;
    • Reconstruction and widening of State Road to two lanes southbound and one lane northbound from Cottman Avenue to Princeton Avenue;
    • Widening of Cottman Avenue (Route 73) to two lanes westbound and one lane eastbound from State Road to Torresdale Avenue; and
    • Construction of a new northbound on-ramp spur from Milnor Street that connects with the on-ramp from Princeton Avenue.
    A third and final contract, Section CP3, will finish PennDOT’s improvements at the interchange with construction of a new southbound on-ramp from Cottman Avenue and completion of the installation of the large water and sewer mains on the west side of I-95. Section CP3 remains under design and scheduled for construction in late 2020 or early 2021.
