The state is in the early stages of assessing whether to replace the 85-year-old bridge along U.S. 54 that spans the Mississippi River near Louisiana, Mo.
The bridge is one of the oldest along the river.
The project is currently in the environmental assessment phase which could take up to two years. During the course of the environmental assessment, MoDOT will hold multiple public meetings which it expects will create a citizen's advocacy group.
Replacing the bridge could cost up to $100 million, which would likely be covered by a combination of federal and state funds. Costs will shared between MoDOT and IDOT, with MoDOT managing the project.
