Volvo Interchange Design-Build

Berkeley County, SC

SCDOT needed a new interchange along I-26 to provide direct access to the newly-built Volvo Manufacturing Facility providing 2,000 jobs to local workers.

The SCDOT selected Conti as its design-build contractor to construct a new three-level, three-leg directional interchange along I-26 in Berkeley County, South Carolina. The interchange will provide access from I-26 to the new Volvo Boulevard leading to Camp Hall Commerce Park and the new Volvo Manufacturing Facility.

 

Conti’s design-build work includes surveys, geotechnical exploration and design, roadway, bridge, traffic and seismic designs, utility coordination, transportation management and HAZMAT studies. The team’s multi-phase construction work will include demolition of existing asphalt pavement; resurfacing and correcting the cross slopes of the existing I-26 mainline within the project limits; performing ground improvements, erosion and sediment controls; and safely maintaining traffic flow. The new interchange includes two ramps at-grade and two flyover, as well as three bridge structures passing over the main interchange and ramps 1 and 4. The team will construct five total miles of new roadway.

 

As part of the benefits of the design-build project delivery method, the project team successfully coordinated early with the SCDOT for timely approval of its comprehensive design submittal packages. Conti broke ground using the full extent of its resources to enable multiple shift construction operations, reduce the overall schedule for early delivery and minimize impact to the traveling public. Conti sequenced construction to facilitate access to the Volvo plant through a partial interchange opening as early as possible in the project, and prior to substantial completion, in an effort to meet the strict project delivery date.

“The construction of this interchange is an important step in providing an interconnected system for driving the state’s economic engine.” – Christy Hall, SC Secretary of Transportation
