Project Purpose and Need

The purpose of the project is to:

  • Improve traffic and safety operations on Highway 1
  • Reduce cut-through traffic diverting to local streets and neighborhoods by
    adding auxiliary lanes between Bay Avenue/Porter Street and State Park Drive
  • Improve bicycle and pedestrian connectivity to regional destinations and
    transit by providing enhanced bicycle and pedestrian facilities for active
    transportation users at Capitola Avenue
  • Add infrastructure for buses to travel in the auxiliary lanes between
    interchanges and on the outside shoulder through interchanges
  • Improve bicycle and pedestrian connectivity to regional destinations and
    transit by providing a dedicated crossing for active transportation users at Mar Vista
  • Connect neighborhoods, schools, parks/beaches and commercial centers
  • Promote the use of alternative transportation modes to increase transportation system capacity and reliability
  • Widen the overcrossing at Capitola Avenue to current standards

This project is needed because:

  • Several bottlenecks along Hwy 1 in the southbound and northbound directions cause congestion during peak hours, significantly delaying drivers. As a result, “cut‐through” traffic—or traffic on local streets—is increasing because drivers are seeking to avoid congestion on the highway.
  • There are limited opportunities for pedestrians and bicyclists to safely navigate SR 1 in 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 Hwy 1 corridor because congestion threatens reliability and cost‐effective transit service delivery.
  • The existing length (i.e., span) of the Capitola Avenue overcrossing cannot accommodate a wider freeway. In addition, the existing overcrossing does not meet current standards for vertical clearance over the freeway, has substandard widths, and does not have bicycle lanes across the bridge. The bridge must be reconstructed to meet current standards.

Environmental Analysis

A joint Environmental Impact Report/Environmental Assessment (known as an EIR/EA) was prepared pursuant to the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA). Caltrans is the lead agency under CEQA and assumed responsibilities of lead agency for the Federal Highway Administration under NEPA assignment.
