State Route 12; Henrieville Area Bridge Work

Project Overview

Starting the week on November 20, 2023 The Utah Department of Transportation will be removing and replacing the Henrieville Bridge and the Smith Ranch Bridge on State Route 12 in the Henrieville, Utah area. The improvements will take about a year to compete with a Winter Shutdown planned from January 20, 2024 to March 19, 2024

Henrieville Bridge: A bypass road will be built to divert traffic around the current bridge while crews rebuild. The team will begin creating the bypass road in November 2024. The bypass road will be paved and opened in March 2024. The bridge will be operational until August 2024. 

Smith Ranch Bridge: This bridge will be constructed one side at a time. Traffic will be managed by a Traffic Light and northbound and southbound traffic will alternate moving across the bridge. Motorists can expect up to a 15 minute delay while waiting to cross the bridge. Construction on this bridge starts in March 2024 along with use of the Traffic Signal.
