I-79 Improvement Project Begins Tuesday Night in Allegheny County

Pittsburgh, PA – PennDOT District 11 is announcing roadway improvement work on Interstate 79 in Glenfield, Sewickley Hills and Franklin Park boroughs, and Kilbuck, Aleppo, and Ohio townships, Allegheny County will begin Tuesday night, September 7 weather permitting.

Lane restrictions and shoulder closures will occur in both directions of I-79 between the Neville Island Bridge and I-279 weeknights from 7 p.m. to 6 a.m. through late November. One lane of traffic in each direction will be maintained during operations.

Crews will conduct longitudinal joint sealing, pavement marking installation, crossover and emergency pull-off construction, and lighting upgrades.  The work is in advance of the long-term traffic pattern change in 2022.

Future 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 2022 and 2023 for bridge deck replacement work. The majority of the project will conclude in the fall of 2023.

The prime contractor on this $26.49 million project is the Joseph B. Fay Company. Work on this project will be coordinated with other projects in the area.
