PennDOT District 11 is announcing single-lane restrictions on McLaughlin Run Road (Route 3004) in Upper St. Clair Township, Allegheny County will begin Friday, April 30, weather permitting.
Starting 7 a.m. Friday, single-lane restrictions will occur around-the-clock on Lesnett Road at the intersection of McLaughlin Run Road through late June. Traffic will be maintained in each direction as crews work to construct a culvert on Lesnett Road and perform sidewalk and guide rail drainage improvements through the intersection. However, the single-lane width will be narrowed to 11 feet in each direction. Temporary traffic signals may be utilized to guide motorists through the intersection.
The $4.67 million project will convert the signalized McLaughlin Run Road and McMillan Road/Lesnett Road intersection into a free-flowing single-lane roundabout. Additional work includes, replacement of two structures, sidewalks and ADA curb cut ramp installation, guide rail and drainage improvements, sign updates, lighting upgrades and pavement marking installation. Traffic will be maintained in each direction throughout the duration of the project. Flaggers and temporary traffic signals will be used to guide motorists through the work zone as needed. Work will be conducted in nine construction phases. Phases one through five will occur in 2021, followed by a winter hiatus. The remaining phases will begin in the early spring of 2022. The overall work will conclude in the Fall 2022. Plum Contracting Inc. is the prime contractor.
Motorists should be prepared for changing traffic patterns. Please use caution when driving through the area. Work zone safety is everyone’s responsibility.
