In 2023-2024 MnDOT replaced the Mendota Bridge railing as part of a project to restore the bridge to its historical nature. In review, MnDOT made the determination to raise the railing from its original 42 inches in heights, which followed federal guidelines and safety standards, to 54 inches, while still working to preserve the historic nature of the bridge.
Prior to 2024, the metal ornamental railing on the Mendota Bridge was in very poor condition and needed to be updated with a goal of meeting all standards. During the design for the railing process, the team ran into the following concerns due to the historic nature of the bridge:
- Bike/Pedestrian railing height
- Historic railing height (from 1926-1994)- 42 inches
- American Association of State Highway and Transportation Officials (AASHTO) minimum height standards- 42 inches
- MnDOT standard railing height- 54 inches
In May 2026, the Minnesota Legislature passed Kayla’s HOPE Act. The new law directs MnDOT to work with the Minnesota Department of Health to create safety guidelines and design standards for prevention fencing on bridge projects. In 2027, MnDOT will add 7 ft. tall prevention fencing on both sides of the Mendota Bridge to increase safety while still following the historic preservation requirements including section 106 to avoid the adverse impact to the character defining features of the bridge.

Summary of work
- Add 7 ft. tall prevention fencing on both sides of the Mendota Bridge over the Minnesota River to enhance safety for people walking and biking.
Traffic impacts
All traffic impacts are tentative and weather dependent.
Upcoming
Information about upcoming traffic impacts will be provided as details become available. Pedestrians and bicyclists can expect a trail closure over the bridge to last spring through late summer 2027; however, we do everything we can to minimize impacts and may open earlier if construction is complete. Motorists can also anticipate narrowed lanes over the Mendota Bridge during construction.
