Port Access Road
Davis & Floyd consulted with SCDOT during the development of the complex Port Access Road (PAR). By forming a direct route between I-26 and the Naval Base Terminal, PAR will improve traffic flow in the area. Commercial and large truck traffic will easily be integrated into the everyday commute. Additionally, PAR will remove large vehicles from local, urban streets creating a safer environment for all.
Conducted field surveys to verify existing surveys provided in the RFP: drainage structures, bridge structures, and key property corners
Provided roadway design services for local roads
Designed hydrologic and hydraulic drainage systems
Designed stormwater system with manufactured treatment devices
Coordinated and designed traffic control
Created bridge and seismic deign for three Bridges: Tidewater Avenue: Curved 746’ flat slab bridge; Bainbridge Connector: 1040’ flat slab bridge; Stromboli Avenue: Curved 645’ bridge consisting of flat slab, Type IV AASHTO girders and 72” modified T beams
Coordinated with utilities and railroad
The urban location required tactful execution to avoid disturbing local regimen.
All excavated material was strictly monitored due to toxicity levels in soil.
In the design-build pre-bid process, Davis & Floyd distinctively reconfigured multiple bridge layouts to decrease area and weight. Not only did this create a smaller footprint, but it also allowed for the use of pile and cap construction, resulting in significant savings for SCDOT.
