Flatiron, along with its joint venture partner Zachry Construction Corp., secured a contract for the Interstate 85/Interstate 385 Interchange project in Greenville, South Carolina.
The $231 million design-build project for the South Carolina Department of Transportation will reconfigure the interchange at I-85 and I-385, improving traffic operations and safety for about 194,000 vehicles per day.
The project will replace existing loop ramps with direct-connect, high-level flyover bridges and includes construction of a new collector-distributor roadway along Interstates 85 and 385. The project also includes reconfiguration and replacement of existing ramps, construction of additional lanes along I-85 and I-385, resurfacing and rehabilitation of I-85.
Crews will design and construct 12 new bridges, rehabilitate two existing bridges and construct retaining walls. The project will also require extensive attention to traffic maintenance to minimize impact on the traveling public.
The new interchange will relieve congestion and increase safety on the third busiest interchange in South Carolina. The project is the state’s largest transportation infrastructure project in over a decade.
The project is led by a joint venture of Flatiron and Zachry Construction, with a design team of Civil Engineering Consultant Services Inc. as the primary designer. Stantec, TYLin, and Mead and Hunt are serving as major sub consultants.
Construction is scheduled to begin in late fall 2015, with completion is expected in 2018.
