STV 100th Anniversary
  Knightdale Bypass Design-Build (Wake County, NC)


STV provided bridge design, roadway design, retaining wall design, and hydraulic design services for this 15.5-kilometer, 6-lane interstate standard roadway on new alignment project. This design-build project includes roadway design and erosion control for 5.8 kilometers of mainline with a diamond interchange at Smithfield Road. The firm faced environmentally sensitive challenges and a very strict permitting process schedule, but the project was completed on time, and it was voted one of the Top 10 Road Projects in 2005 by Better Roads Magazine.
