Pittsburgh, PA – PennDOT District 11 is announcing a traffic crossover on southbound Interstate 79 in Glenfield, Sewickley Hills, and Franklin Park boroughs and Ohio and Aleppo townships, Allegheny County, will begin Saturday, February 18.

A southbound crossover on I-79 will be implemented at approximately noon on Saturday to allow crews to begin bridge deck replacement work. To accommodate this work, the following traffic configuration and restrictions will occur: 

• The left lane of southbound I-79 will be crossed over into the northbound lanes between the I-279 and the Red Mud Hollow Road overpass. This is the EXPRESS lane. All traffic using this lane will not have access to the Mt. Nebo Road (Exit 68) or Emsworth/Sewickley Route 65 (Exit 66) interchanges. Southbound express lane traffic will be crossed back over between the Emsworth/Sewickley Route 65 (Exit 66) interchange and the Neville Island Bridge. 

• The right lane of southbound I-79 will remain in place. This is the LOCAL lane. Access to the Mt. Nebo Road (Exit 68) and Emsworth/Sewickley Route 65 (Exit 66) interchanges must be made from the local lane. Traffic will be shifted slightly at the Red Mud Hollow Road and Glenfield Road bridges to allow crews to conduct half width deck replacement work.

• Two lanes of traffic will be maintained on northbound I-79. A barrier will separate the northbound lanes and the crossed over southbound lane.

• Emergency pull-off areas will be implemented in various locations through the work zone. Three pull-off areas will be implemented in the northbound lanes, three in the southbound express lane, and three in the southbound local lane.

• The southbound crossover will remain in place continuously through late-November.

To prepare for the crossover, single-lane restrictions and traffic stoppages will occur on northbound and southbound I-79 from 9 a.m. Friday until approximately noon Saturday. The crossover is anticipated to be in place shortly after noon on Saturday.

While the crossover is in place, crews will conduct bridge rehabilitation work on the southbound structures over Glenfield Road and Red Mud Hollow Road in half-widths. This work includes bridge deck replacement, approach slab work, bearing pad and expansion dam replacement, substructure concrete repairs, and downspout upgrades.

The work is part of the $26.49 million I-79 improvement project. Improvements include four bridge deck replacements, one bridge preservation, milling and resurfacing, preservation work on seven sign structures, installation of five new ITS signs, guide rail improvements, signage updates, and pavement marking installation. Crossovers will occur on I-79 in 2023 for bridge deck replacement work. The majority of the project will conclude in the spring of 2024.

The prime contractor is the Joseph B. Fay Company. Work on this project will be coordinated with other projects in the area.
