Flatiron and Zachry Construction Corp. have been awarded a $231 million design-build contract to reconfigure the Interstate 85/Interstate 385 interchange in Greenville.
The contract is with the South Carolina Department of Transportation. The project will address traffic operations and safety at an interchange used by about 194,000 vehicles per day.
The work will replace existing loop ramps with direct-connect, high-level flyover bridges and add a collector-distributor roadway along I-85 and I-385.
The project also includes reconfiguring and replacing existing ramps, adding lanes along both interstates, and resurfacing and rehabilitating I-85.
The joint venture will design and construct 12 new bridges and rehabilitate two existing bridges. Retaining walls will also be constructed, with traffic management required throughout the project to maintain operations during construction.
The interchange is the third-busiest in South Carolina. The project is described by SCDOT as the state’s largest transportation infrastructure project in more than a decade.
The design team is led by Civil Engineering Consultant Services Inc., with Stantec, TYLin and Mead & Hunt serving as major subconsultants.
Construction is scheduled to begin in late fall 2015, with completion planned for 2018.
Flatiron has previously worked on major South Carolina projects, including the Arthur Ravenel Bridge in Charleston and Carolina Bays Parkway in Myrtle Beach. Zachry has completed the I-20 widening project in Richland County and was also working on the I-40/I-77 project in Iredell County, North Carolina.
