Highway 1 Auxiliary Lanes and Bus-on-Shoulder Improvements —Freedom Boulevard to State Park Drive— and Coastal Rail Trail Segment 12 Project

Project Description

The California Department of Transportation (Caltrans), in association with the Santa Cruz County Regional Transportation Commission and the County of Santa Cruz (County), proposes improvements along State Route 1 and the Santa Cruz Branch Line railroad right-of-way, within an unincorporated area of the County. Improvements under consideration include the construction of auxiliary lanes, implementation of bus‐on‐shoulder operations, widening and replacement of bridges, construction of Segment 12 of the Coastal Rail Trail, and the installation of sound walls and retaining walls.

Project Benefits


  • Reduce delay and improve system reliability and safety along State Route 1
  • Improve traffic operational movements, local circulation, and transit operations
  • Enhance bicycle and pedestrian connectivity and safety, including access across State Route 1 within the project limits
  • Promote the use of alternative transportation modes to increase transportation system capacity and reliability, improve health and reduce mortality, as well as to reduce vehicle miles of travel and vehicular emissions


  • Several bottlenecks along State Route 1 in the southbound and northbound directions cause delays during peak hours, significantly delaying drivers
  • Cut-through traffic, or traffic on local streets, is increasing because drivers are seeking to avoid delays on State Route 1
  • There are limited opportunities for pedestrians and bicyclists to safely cross State Route 1 and navigate the project corridor, even though portions of the project area are designated as regional bicycle routes
  • There are insufficient incentives to increase transit service in the State Route 1 corridor because delay threatens reliability and cost‐effective transit service delivery


Estimated Funding Breakdown

Construction Cost: $79,000,000
