I-15 | Cove Fort to Manderfield | Bridge Work

I-15 | Cove Fort to Manderfield | Bridge Work

Replaces three I‑15 bridges and rehabilitates a box culvert between Cove Fort and Manderfield to improve structure condition and support safe, reliable travel in Millard County.

 

Project Overview

The I-15 Cove Fort to Manderfield Bridge Work will replace three bridges and rehabilitate one box culvert in Beaver and Millard County. The bridge replacements are located on the Manderfield Interchange (Exit 120), Sulphurdale Interchange (Exit 129), and Cove Fort Interchange (Exit 135). The culvert rehabilitation is located near milepost 134.32, adjacent to Beaver County Road 3397.

The goal of this project is to bring the bridges and box culvert into a state of good repair while continuing to support safe, reliable travel for all users of the corridor.

If you own property, operate a business, or regularly use one of the bridges between Cove Fort and Manderfield, we encourage you to complete our survey. Your feedback will help the project team understand current bridge use, assess potential impacts of temporary closures, and consider local access needs as planning moves forward.
