Project Status and FAQs for the San Martin Blvd. Bridge Replacement Study

San Martin Blvd over Riviera Bay bridge replacement area

Project Status

An assessment of potential impacts has been conducted for alternatives developed and evaluated during the study. These alternatives were presented to the community at the Alternatives Workshop in 2016. Visit the Community Outreach page to view the information provided at the workshop.

A Preferred Alternative has been selected based on consideration of potential environmental impacts, social and physical impacts, engineering issues and public input received throughout the study. The PD&E study is anticipated to be completed in Spring 2022.

Why is the project needed?


The study of San Martin Boulevard Bridge is needed in order to address the deficiencies of the existing bridge. The bridge was constructed in 1962 and is nearing the end of its service life. The existing bridge does not meet current design standards and Americans with Disabilities Act (ADA) requirements. This study is being undertaken in accordance with the federal National Environmental Policy Act (NEPA) process. The NEPA process will allow the County to remain eligible for federal funding.

What is the purpose of the study?

The purpose of the study is to develop and evaluate alternatives for proposed improvements to the existing bridge and determine the best option (Preferred Alternative). The preferred alternative should meet transportation needs, address engineering concerns and minimize environmental, social and physical impacts. Various roadway improvements, bridge types and bridge locations have been evaluated including left, center or right of the existing bridge. The study focused on alternatives for the bridge including:

  • No build (required to be considered in the NEPA process).
  • Rehabilitation of the existing bridge.
  • Replacement of a new fixed bridge.
  • Replacement of a new movable bridge.
