The bridges were built with two side-by-side steel tub girders. This design allowed longer bridges to be built while using fewer lifts, as well as maintaining uniformity with the Marquette and Mitchell interchanges. Due to the of steel needed for the project, WisDOT held meetings with steel fabricators and construction contractors to understand the necessary logistics. It was determined that contractors would need to buy from at least two steel manufacturers to obtain the necessary quantity. A bill of materials was released in advance, giving contractors two to three months to obtain the steel before the work was scheduled to begin. Six 31-hour windows were scheduled for installing beams, and deliveries of beams were coordinated to occur during off-peak traffic times. The use of chainfalls to guide the beams into place and bigger cranes than expected reduced the time needed to install beams to 12–15 hours per window.
