Mall Drive

This project consisted of two new bridges, shoulder widening and two new median aux lanes, including connecting underpass of frontage roads which parallel the Interstate from St George Boulevard to Green Springs Drive.

Key elements for the project included; soil nail retaining walls, accelerated construction techniques, partial-depth deck panels, ATMS fiber, slip-formed median barrier and high-early-strength concrete was used for all the bridge structures.

To meet the Utah Department of Transportation’s aggressive schedule timeline, WBC utilized its expertise in scheduling using proven techniques, reliable suppliers, high quality subcontractors and innovative traffic control movements. Multiple crews worked continuously around the clock to perform the work with most of the roadwork being performed a night to lessen traffic impacts.
