Third Public Meeting



Nearly 300 residents, organizations and other stakeholders joined an interactive, online public Meeting on October 27, 2022, to receive an update on the I-80 Mississippi River Bridge project, review recommendations on a narrowed list of potential improvement alternatives, and provide feedback to the project team.


Following a video presentation and viewing of study exhibits, participants asked questions and provided feedback directly to representatives of the Illinois and Iowa Departments of Transportation.
