Kiewit designed and built an elevated tollway connecting the Selmon Expressway to Gandy Bridge in Florida, USA (pictured, image courtesy of Kiewit).

Kiewit鈥檚 appointment comes after the US Department of Transportation awarded nearly $400 million towards half the cost of replacing the bridge, in July 2024.

In addition to the nearly $400 million from the Rebuilding American Infrastructure with Sustainability and Equity (RAISE) programme, the Tennessee Department of Transportation (TDOT) and the Arkansas Department of Transportation (ARDOT) have each committed up to $200 million.

The environmental process is concluding on the I-55 Bridge Replacement project. Design is underway and construction is due to start in Kiewit鈥檚 2026 fiscal year.

The new bridge will be a larger structure than the existing 75-year-old bridge, and will be designed to meet modern seismic codes, as it sits on the New Madrid fault line.

Deputy Governor and TDOT commissioner Butch Eley said, 鈥淲e are thrilled to partner with the US Department of Transportation, Arkansas, and now Kiewit, whose proven track record will be invaluable to the success of this transformative project to enhance regional and national connectivity and safety significantly. We look forward to its positive impact on our state and country for decades to come.鈥�

Dave Miles, executive vice president of Kiewit Corporation, added, 鈥淜iewit is very pleased to have been selected to help deliver the bridge replacement project for the Tennessee and Arkansas Departments of Transportation.

鈥淲e have a long history of safely building and engineering complex bridge and transportation projects across the United States, including in both states. We are excited to bring our experience and skilled workforce to this project, which importantly connects both states for people within and traveling through the region.鈥�
