Project background

The original 1933 Sabula Bridge at U.S. 52 across the overflow waters of the Mississippi River needed to be replaced. The replacement bridge is being built along the existing alignment on new piers. Due to limited right-of-way in the project area, we are not able to construct the replacement bridge next to the alignment without the loss of homes and properties. A limited closure of about 40 days was originally planned for this project, with work beginning late September 2017, and a new Sabula Bridge opening to traffic Memorial Day 2018.


On February 27, 2018, we discovered the previous Sabula Bridge was settling at one of its pier locations, causing it to be unsafe for traffic. The bridge was immediately closed for the safety of the traveling public.

This early closure impacted the contractor's previously planned staging areas and schedules, this coupled with flooding and sandy soils in the project area, continue to create problems and delays for the project completion.


We understand the longer than expected closure can have significant impacts on your ability to move through the area and for on the economic vitality of the surrounding communities. Therefore, it is essential that we put safe options in place as soon as possible to keep you moving through the area.


A pre-planned detour went into effect immediately following the closure at the original Sabula Bridge. 

Traffic moving from Iowa to Illinois - Take U.S. 67 south to Iowa 136 east in Clinton, crossing the river on the Iowa 136 Bridge. Take IL 84 north to connect with U.S. 52 in Savanna, IL.

Traffic moving from Illinois to Iowa – Take IL 84 south to Iowa 136 west, crossing the river on the Iowa 136 Bridge. Take U.S. 67 north to connect with U.S. 52 in Sabula.

The detour is estimated at 36 miles in length – approximately 50 minutes in duration.

Mobility options

We understand an extended closure time of the Sabula Bridge coupled with a lengthy detour is not ideal. We have been studying a variety of transportation options. There are feasibility, safety, environmental, and economic considerations for each of these options that must be explored carefully before an option can be implemented. More information will be posted on available options in the Mobility and Construction Update and Frequently Asked Questions once it is available.

Mobility and Construction Update

Please note that weekend traffic may be heavier. Travelers should plan ahead and expect potential extended wait-times at ferry queuing locations.

Additionally, the temporary stationary span Bridge, floating bridge, and military bridge options are no longer being considered due to a number of factors including: availability of vendor services, timing for mobilization, and cost of services.

Work has begun on placing the two remaining piers. To view the construction effort, visit our live web cam. Once placement of the pier shafts is completed we will have a better idea of schedules moving forward. We are still targeting to open the new bridge to traffic by Labor Day.
