I-10 / US 301 Interchange

The Work

Superior is constructing 1.9 miles of roadway, replacing four bridges, and building four additional bridges on a route with heavy traffic. In addition to the traffic challenge, the bridges are built over a CSX Railroad railyard, which means the timing of the work must be precise to coordinate with the CSX right-of-way. When the initial design stalled because the work could not be completed to align with CSX traffic, Superior collaborated with FDOT and a new designer to create an improved design.

The Superior team coordinated and cooperated with FDOT and CSX during the redesign process to have all plans approved. The new design bypassed many construction complexities of the initial design. The new plan eliminated the need for a bent in the CSX railyard and instead includes one span that stretches across the railyard, reducing construction interference with the railroad. This is accomplished using 235-foot long weathering steel beams, which weigh 300,000 pounds per pick. Superior used their cranes to perform tandem picks.
