The South Carolina Department of Transportation is rehabilitating the South Carolina Route 703 (Ben Sawyer Bridge) steel thru-truss swing span bridge over Intracoastal Waterway in Charleston County. The new approach superstructure will be constructed on-site and rolled into place. The swing span and its components will be built off-site and barged into place. The traffic impact will be limited to 7 days versus 8 months if traditional construction methods were used. The modular construction method will greatly enhance work zone safety by minimizing worker’s exposure to traffic hazards. The quality and workmanship will also be improved as the swing-span is fabricated, assembled and inspected in a controlled environment.
This Showcase will include presentations from FHWA and SCDOT, as well as the contractors who worked on this project.
Topics include:
- National Perspective on Accelerated Bridge Construction
- Traditional vs. Accelerated Bridge Construction
- SCDOT's Process (construction, lessons learned, etc.)
- Contractor's Perspectives
- A visit to the Ben Sawyer Bridge
