Marshall Petaluma Road milepost 6.40 – Slide Repair

Description

Overview

Winter storms during February 2019 caused a slip out on the eastbound direction of Marshall Petaluma Road at milepost 6.40.  This project proposes to install a retaining wall and drainage improvements to restore the roadway shoulder area.

Funding

The  estimated $300,000 project will be funded through the Federal Highways Administration’s Emergency Relief Funds plus a local match.

Traffic Impacts

It is expected that one-way access with alternating two-way traffic control will be implemented. There would likely be traffic delays of up to five minutes. Specific traffic control measures and impact details will be publicized once construction plans are approved.
