Engineering designs for the reconstruction of three of nine bridges classified as "unsafe" by the Utah Department of Transportation are under way as Duchesne County begins a bridge replacement project.
As the first step in the multiyear bridge replacement project Du-chesne county commissioners recently hired a Salt Lake engineer to redesign three of the faulty structures.The old wooden bridges were targeted by U-DOT officials last fall for replacement. Three of the bridges in the worst shape, all spanning the Strawberry River, will be the first to be replaced with concrete structures sometime next year.
The design chosen for those three will continue to be used as the county eventually replaces the remaining six bridges, also located on the Strawberry River and in the Rock Creek area, according to Larry Ross, Duchesne County commissioner.
Eighty percent of the replacement cost will come from state and federal funds. The county will make up the remaining 20 percent. It will cost an estimated $300,000 to replace all nine bridges.
