The widening of I-385 in Greenville County, SC, provided traffic relief for more than 60,000 motorists using the busy interstate every day. STV was the design manager for the $65 million design-build program, which widened 5.5-miles of the interstate from four lanes to six lanes and resurfaced another 1.5 miles of roadway. The South Carolina Department of Transportation project also involved reconstruction of several ramps to meet design standards and the 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 completed project was honored with Engineering Excellence Awards from the South Carolina and national chapters of the American Council of Engineering Companies.
