Project Description

The 4400 South bridge over I-15 and two I-84 bridges over 4400 South between the cities of Roy and Riverdale will be replaced. Construction will begin in late July 2025, with plans to finish in late 2026. 

To improve quality of life and accommodate the ever-growing needs of our state, UDOT is committed to keeping Utah moving both now and in the future. We monitor the health of our infrastructure because safety is our priority. Inspections allow us to act well in advance to replace structures on their way towards disrepair. We are partnering with the cities of Roy and Riverdale to make these improvements to local infrastructure to reduce disruption to the community.
