STV was the design manager for a $65 million design-build project to widen 5.5-miles of I-385 in Greenville County from four lanes to six lanes and resurface another 1.5 miles of roadway. The South Carolina Department of Transportation project also involved reconstruction of several ramps to meet design standards and widening of the dual bridges at Exits 30 and 31.

STV and Lane Construction Corp., the contractor, developed an innovative maintenance and protection of traffic plan involving a temporary access ramp to the I-385 median to provide construction access and accelerate the schedule. The project, which was completed in December 2012, is the largest American Recovery and Reinvestment Act-funded transportation initiative to date in South Carolina.
