South Carolina Department of Transportation and Horry County select Stantec to lead design of $840 million SC90 road widening project

Significant infrastructure investment will improve mobility in one of South Carolina’s fastest-growing regions

12/16/2025 COLUMBIA, SC TSX, NYSE:STN

Stantec, a global leader in sustainable design and engineering, has been selected to lead the design for the SC90 East Cox Ferry Road widening project, led by the South Carolina Department of Transportation and Horry County. The project will widen approximately 23 miles of roadway and will expand the corridor from two lanes to five. The expansion efforts will also introduce new sidewalks and shared-use paths along the corridor.

The corridor primarily serves local residents and is being expanded to address rapid population growth and increased traffic congestion in Horry County, which includes the Myrtle Beach metropolitan area. The roadway expansion will also look to improve safety throughout the corridor and aim to reduce fatal and serious injury crashes. Horry County is ranked within the top 100 counties in the country for annual growth, with the Myrtle Beach-Conway-North Myrtle Beach metropolitan area ranking as the third-fastest growing metropolitan area in the United Sates.

Construction of the SC90 road widening project will be segmented into up to four phases. The project is funded by the Horry County RIDE 4 Sales Tax Commission.

“The growth Horry County and the broader Myrtle Beach metropolitan area has seen in recent years has been incredible to see,” said Bret Gillis, senior transportation engineer and project manager at Stantec. “Our team is proud to be leading the design efforts in this pivotal project. Together, with the SCDOT and Horry County, we welcome the opportunity to improve safety and connectivity for residents along this essential corridor.”

Stantec has a long history of supporting roadway design across the United States. The firm served as prime consultant on the Route 3, Route 46, Valley Rd. & Notch Rd. Interchange Reconstruction Project in New Jersey, a project aimed at reducing congestion, improving safety, and increasing connectivity from Northern New Jersey to Manhattan. Stantec also led the design efforts for the improvements of the Golden Glades Interchange, a project that improved movement southbound along Florida’s Turnpike.
