Most Traveled Bridges in Utah

The busiest bridge in Utah carries 268,370 vehicles per day. The table below ranks the state's bridges by average daily traffic — these are the structures where condition matters most, because a closure or weight restriction affects the largest number of commuters and freight haulers.

How this ranking works

Average daily traffic is reported by state transportation agencies and can trail real-world growth or detours. BridgeLookup uses it to rank likely disruption impact across comparable records.
