Mt Murphy Bridge Project

Welcome to the El Dorado County Mt. Murphy Road Bridge project website.

Project Overview

The Mt. Murphy Road Bridge is an existing steel truss bridge built in 1915 and is over 100 years old. The main span is 160-feet long with two concrete approach structures of 140-feet and 60-feet long, which were rebuilt in 1931. The bridge approaches are narrow (10.5-feet). The bridge is classified as structurally deficient and functionally obsolete. The Mt. Murphy Road Bridge meets federal criteria for replacement and funding under the Highway Bridge Program Off Federal Aid System 100% Reimbursement Program.

The County conducted an array of public meetings with the public who are directly affected on a daily basis.

All materials and documents used during the public outreach as well new information and announcements as they become available are provided through the links below.

Transportation is currently in the Right of Way phase and 65% Design phase. Utility relocations are anticipated to begin late 2025, one year in advance of the bridge replacement construction.
