SPANISH FORK — The Utah Department of Transportation has begun repair work for a bridge on U.S. 6 near the mouth of Spanish Fork Canyon.

The project will extend the life of the bridge east of I-15 and over the railroad. The existing bridge deck will be replaced with updated materials and part of the aim of the project is to provide a smoother ride for motorists.

Work began Aug. 17 and is expected to finish by the end of September. Crews will work seven days a week, but not over Labor Day weekend.

Crews will install a new asphalt road surface and the existing bridge deck will be removed and replaced in phases.

From Sept. 2 through about Sept. 19, traffic will be reduced to a single shared lane with a signal light to control traffic through the construction zone. Motorists should expect delays of up to 30 minutes during this phase.

On Sept. 14-15, the bridge will be closed to all trucks for 24 hours to allow concrete to cure. Westbound trucks are advised to take U.S. 89 to state Route 75/1400 North and eastbound trucks are advised to take state Route 77/400 South to U.S. 89.
