Marina to Castroville CAPM

Project Description

The California Department of Transportation (Caltrans) proposes to preserve 22.2 lane miles of Class 2 pavement on State Route 1 in Monterey County, including gore area paving. The project would also rehabilitate one drainage system, replace Traffic Management Systems elements, improve lighting, address bicycle and pedestrian infrastructure, and upgrade guardrail to the Manual for Assessing Safety Hardware (MASH) standards. The project stretches from 0.28 mile south of the South Marina Overhead (Bridge No. 44-211L) to the junction of State Routes 1 and 156. Caltrans is the lead agency under the California Environmental Quality Act (known as CEQA). Caltrans is also the lead agency under the National Environmental Policy Act (known as NEPA). Caltrans has determined that the project qualifies for a Categorical Exclusion under NEPA and will complete that documentation before project approval.

Project Benefits


The purpose of the project is to preserve and extend the service life of the existing pavement and facilities. In addition to preserving the pavement, the project will restore culverts that are in poor condition to protect the embankment and roadway from potential slope failure, replace guardrail systems to meet current standards, and restore Traffic Management Systems elements in poor condition to allow for effective traffic management. As a result, over time, the project will reduce the amount of maintenance worker exposure from high-speed traffic by providing an improved work environment for maintenance personnel and an upgraded facility for the traveling public.


Deteriorating pavement conditions within the project limits require pavement rehabilitation. Without rehabilitation, further deterioration of the pavement will result in failure of the underlying bearing materials, requiring more costly and ongoing reconstruction of the roadway. Traffic Management Systems elements, gore area paving, and guardrail systems are either at the end of their service life, not present, or are not up to current standards. If these are not addressed, the results would be higher costs, more frequent maintenance activities, and possible disruption of service for the facility.
