Preserving the Mantua Bridge deck to extend its lifespan and prevent costly repairs, ensuring long-term travel reliability.
PROJECT UPDATE 10/09/25: There will be no lane closures from October 16–19. Intermittent daytime closures will begin October 20 and continue through the end of the month, finishing out the project.
Project Description
The Utah Department of Transportation (UDOT) is carrying out critical preservation work on the Mantua Bridge deck in both directions. This project is designed to extend the bridge’s service life and prevent the need for more extensive—and costly—repairs in the future. By addressing wear and tear early, UDOT is enhancing safety, improving long-term travel reliability, and delivering cost-effective solutions for Utah taxpayers.
Construction began in late March. Since then, crews have been hard at work removing deteriorated surface materials, performing structural repairs, and preparing the bridge for resurfacing.
During construction, lane closures will be in place; however, at least one lane in each direction will remain open at all times to maintain traffic flow. Drivers should expect delays, particularly during peak travel hours, and are encouraged to plan ahead, reduce speed, and exercise caution through the work zone.
