# IDOT Advances Quad Cities Bridge Projects

The Illinois Department of Transportation is advancing two Mississippi River crossings in the Quad Cities, with Illinois and Iowa sharing costs equally. The **$481 million I-80 crossing** is scheduled to begin construction in 2028 and includes new eastbound and westbound spans and reconstruction of the I-80/I-88 interchange. The **$300 million U.S. 67 Centennial Bridge** is anticipated around 2032; its preferred location is west of the existing bridge, while the bridge type and design remain under development. No solicitation or contract award has been announced.

- Contractors can use the project timelines to inform long-range pursuit planning: I-80 construction is expected to start in 2028, while the U.S. 67 project is anticipated after the I-80 bridges are completed.
- Design development and land acquisition are relevant pre-construction activity areas for firms positioning for future work.
- Companies should distinguish these announced project plans from active procurement opportunities; the signal identifies no current solicitation or award.
