PennDOT District 11 is announcing an overnight ramp closure on I-79 in Collier and Robinson townships, Allegheny County, will occur Friday night, August 8 weather permitting.
An overnight closure on the southbound I-79 ramp to eastbound I-376 (Exit 59A) will occur from 6 p.m. Friday night until 7 a.m. Saturday morning as crews conduct concrete base repairs. Traffic will be detoured.
Posted Detour
Southbound I-79 to eastbound I-376
- From southbound I-79, take the Carnegie (Exit 57) exit
- Turn left onto West Main Street
- Take the on-ramp to northbound I-79 toward Erie
- Take the Pittsburgh (Exit 59A) exit
- End detour
Additionally, as crews work, a shoulder closure will occur on eastbound I-376 near the on-ramp from southbound I-79.
The work is part of the $12.6 million project on the Parkway West located between the Ridge Road (Exit 61) and I-79 (Exit 64A) interchanges in Robinson and Collier townships. Additionally, milling and paving on I-376, ramp preservation work, overhead sign structure repairs, drainage improvements, guide rail updates, and sign and pavement marking installation work will occur in 2025. Restrictions include the long-term closure of Boyce Road, ramp closures, overnight single-lane restrictions, and four weekend-long single-lane closures. The majority of the project is anticipated to be completed in late 2025, however, punch list work is expected to continue through January of 2026.
