Flatiron–Zachry Joint Venture to Build $231 Million Interchange in South Carolina

October 16, 2014

Firestone, Colorado – Flatiron, one of the largest infrastructure contractors in North America, along with their joint venture partner Zachry Construction Corporation, have 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.

“This is the third major transportation infrastructure project Flatiron has secured in the Southeast in the past year,” said Javier Sevilla, chief operating officer of Flatiron and head of the company’s Civil Division. “We look forward to successfully completing this vital project as we continue to expand our presence in the region.” 

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 Corp., with a design team of Civil Engineering Consultant Services, Inc. as the primary designer, along with Stantec, TYLin, and Mead and Hunt as major subconsultants. Construction is slated to begin in late fall 2015, and scheduled for completion in 2018.

Flatiron and Zachry have experience independently constructing other major projects in South Carolina and the Southeast. Flatiron built the Arthur Ravenel Bridge over the Cooper River in Charleston, completed in 2005, and the Carolina Bays Parkway in Myrtle Beach, completed in 2002. Zachry completed the Interstate 20 widening project in Richland County in 2014 and is currently working on Interstate 40/Interstate 77 in Iredell County, North Carolina.
