Single-lane closure starts Friday night for preparatory work
PennDOT District 11 is announcing a traffic crossover on southbound Interstate 79 in Kennedy, Robinson, and Neville townships, and Glenfield Borough in Allegheny County will begin Sunday, June 4.
A southbound crossover on I-79 will be implemented at approximately 12:01 a.m. Sunday to allow crews to begin median widening and roadway reconstruction 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 southern end of the Neville Island Bridge and the Route 60 North/Moon Run (Exit 60B) interchange. This is the EXPRESS lane. Southbound express lane traffic will be crossed back over before the Route 60 North/Moon Run (Exit 60B) interchange.
- The right lane of southbound I-79 will remain in place. This is the LOCAL lane. Traffic will be shifted slightly onto the shoulder for additional space for the crews to 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. Six pull-off areas will be implemented in the northbound lanes, six in the southbound express lane, and seven in the southbound local lane.
- The southbound crossover will remain in place continuously through late-November.
To prepare for the crossover, single-lane restrictions will occur on northbound and southbound I-79 from 7 p.m. Friday until the crossover is implemented by approximately 12:01 a.m. Sunday. However, the crossover could begin earlier if preparatory work is completed sooner.
While the crossover is in place, crews will conduct bridge rehabilitation work on the southbound structures over Route 51 and Clever 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
This work is part of the $43.9 million I-79 “S-Bend” Project that includes full-depth pavement reconstruction, bridge preservation work on five mainline structures (I-79 northbound and southbound over Clever Road, I-79 northbound and southbound over Route 51, and the Neville Island Bridge). Additionally, there will be milling and paving of three ramps at the Route 51 (Coraopolis/McKees Rocks) interchange. The project also includes guiderail replacement, highway lighting and signing upgrades, new pavement markings and delineation, and other miscellaneous construction work.
The prime contractor is Lindy Paving, Inc. Work on this project will be coordinated with other projects in the area.
