US 17 Bypass at SC 707/Farrow Parkway
STV redesigned the $120 million US 17 Bypass at SC 707/Farrow Parkway interchange in Myrtle Beach, SC, known locally as the “back gate,” replacing the at-grade intersection with dual 1,250-foot-long bridges. The firm was contracted by Horry County and the South Carolina Department of Transportation to provide complete turnkey services, including project management, environmental documentation, permitting, traffic analysis, roadway and bridge design, utility coordination, hydraulic analysis, and geotechnical investigations.
Due to the project’s proximity to the South Carolina coast, poor-bearing soils required geotechnical modifications to support the structure, roadway, walls and drainage features. Additionally, since the project area is located near one of the most active earthquake zones on the East Coast, numerous seismic issues were addressed during the design phase.
