Port Access Road, SC
Owner: South Carolina Ports Authority (SCPA)
Location: Charleston, SC
Project Cost: $220 million
Project Type: Highways & Bridges | Procurement Type: Design-Build
State: South Carolina | Status: Ongoing
The Port of Charleston is the fastest growing major container port in the U.S. A new direct access viaduct from the port to I-26 and interstate improvements will allow for the uninterrupted flow of goods to inland areas along the east coast.
Fluor-Lane South Carolina LLC was selected by the South Carolina Department of Transportation (SCDOT) to design and build the Port Access Road Project in Charleston. The project includes interstate improvements and interchange realignment/construction; a new viaduct connecting I-26 to the Hugh K. Leatherman Sr. Terminal; and surface street and bridge reconstruction. This will provide improved service for local and commuter traffic and allow safe integration of container terminal traffic with existing operations.
The project focuses on modification of exits 217 and 218 on I-26, featuring a three-level flyover interchange. Several local bridge structures will be constructed, along with a major bridge replacement at Stromboli Avenue. The new direct access roadway from I-26 to the port terminal is an elevated viaduct which avoids various impediments such as railroad crossings, tidal creeks, and hazardous material locations. Bridge foundation testing at the project site, located on the former Charleston Naval Complex, revealed a variety of hazardous materials, so the team selected a specific foundation type to reduce risks associated with excavation.
Construction elements feature:
- More than 1.2 million square feet of new bridge deck
- A new fully directional interchange on I-26 to serve both commercial and local traffic
- A new connector road and extension of Stromboli Avenue
- Associated roadway improvements to surface streets that will serve the proposed Naval Base Terminal in Charleston County
The design-build scope of work includes roadway, bridge, local road relocation and paving, drainage, existing utility relocations, erosion control, MSE and retaining walls, demolition, and noise barriers.
Benefits/Positive Impact to Community:
- Construction noise mitigation strategies were implemented to minimize noise impacts to adjacent residential and business areas.
- The project team worked closely with local and regional planners to support long-term planning strategies and policies.
- The project provides container terminal traffic with access to I-26 and efficient integration with existing traffic.
