Study Overview

We are conducting a State Environmental Study (SES) to evaluate the extension of State Route 177 (SR-177) from 1800 North in West Point to approximately 4000 South in West Haven. The purpose of this SES is to continue efforts to meet current and future transportation needs in western Davis and Weber Counties. Environmental resources in the area will be evaluated as part of the study. The study is expected to last through late 2026.
