Hwy 1 Retaining Wall Project between Jenner and Fort Ross

Retaining Wall Project on Hwy 1 in Northern Sonoma

Requires Year-Long One-Way Traffic Control

Project to build a half-mile retaining wall on cliffside begins in mid-November 2022

Hwy 1 Retaining Wall

As part of a project to install a retaining wall along Highway 1 in northern Sonoma County, Caltrans will implement one-way traffic control starting in mid-November 2022 and lasting until early 2024.

The project is in a sparsely populated area about a quarter mile north of Myers Grade Road, and about five miles north of Jenner and five miles south of Fort Ross.

During the project, Caltrans will construct a half-mile long retaining wall on the coastal side of Highway 1. The southbound lane will be closed to allow room for construction. Traffic will be controlled by traffic signals mounted at both ends of the project.

The retaining wall will be built about a mile south of a recently completed retaining wall project, where in 2020/21, Caltrans replaced four retaining walls that were badly damaged in the Myers Fire of August 2020.
