Route 50 Millers Run Road Ramp to Northbound I-79 Closed Aug. 12 - Aug. 22

PennDOT is closing of the ramp that carries traffic from Route 50 (Millers Run Road) to northbound I-79 in South Fayette beginning Friday night, Aug. 12 weather permitting.

Beginning at 9 p.m. Friday night, Route 50 ramp to northbound I-79 will close to traffic around-the-clock through 6 a.m. Monday, Aug. 22. Crews will conduct ramp widening and reconstruction work as part of the Route 50 Chartiers Bridge replacement project. Ramp traffic will be detoured.

Posted Detour:

  • From Route 50 (Millers Run Road) continue past the closed ramp

  • Turn left onto the southbound I-79 ramp toward Washington

  • From southbound I-79, take the ramp to Southpointe/Hendersonville (Exit 48)

  • Turn left onto Southpointe Boulevard

  • Turn right onto the ramp to northbound I-79 toward Pittsburgh

  • Follow northbound I-79 back to the closed ramp

Additionally, motorists can follow eastbound Route 50 (Washington Pike) to the I-79 Heidelberg/Collier (Exit 55) interchange to access northbound I-79.

The work is part of the $10.78 million Chartiers Bridge replacement project over Chartiers Creek which will be widened to seven lanes using Accelerated Bridge Construction techniques. Additionally, an exclusive lane from southbound Washington Pike to northbound I-79 will be constructed, widening work will occur on the northbound I-79 on-ramp, and Chartiers Street will be widened to include a turning lane.

The Joseph B. Fay Company is the prime contractor.
