Southbound I-79 Express Lane Closure Saturday in Allegheny County


Pittsburgh, PA – PennDOT District 11 is announcing the closure of the left-hand express lane on southbound Interstate 79 in Glenfield, Sewickley Hills, and Franklin Park boroughs and Ohio and Aleppo townships, Allegheny County will occur Saturday, March 18 weather permitting.

The crossed over left-hand express lane on southbound I-79 will close to traffic from 5 a.m. to 3 p.m. Saturday to allow crews to conduct shoulder repair work. All southbound I-79 traffic will use the right-hand local lane.

Please slow down and allow extra time when traveling through the corridor.

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 southbound I-79 in 2023 for bridge deck replacement work. The majority of the project will conclude in early 2024.

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