Pennsylvania Turnpike Commission


$800 million

This 13-mile section of PA Turnpike 576 (or the Southern Beltway) is located between U.S. Route 22 and Interstate 79 and connects the Findlay Connector, an existing six-mile beltway section. The Southern Beltway connects to I-79 at the Allegheny-Washington County line. The goal of the project was to ease congestion on Pittsburgh area arteries like the Parkway West, I-79, and State Route 50.

RIG Consulting, Inc., was a subconsultant to multiple primes on Sections 55B, 55C1-1, 55C1-2, 55C2-1 and 55C2-2. Inspection staff included a Transportation Construction Inspection Supervisor – 1, two Transportation Construction Inspectors, and a Precast Inspector. This project included the inspection and documentation services of operations for E&S control items, earthwork, drilling and mine grouting, drainage including storm inlets and culvert placement, bituminous pavement placement, stream diversion, seeding, roadway grading, and sedimentation pond construction.
