About the Project

The Lithium Valley Transportation Connectivity Project  is focused on accommodating growth associated with Phase 1 of the Lithium Valley Specific Plan by improving transportation access to the geothermal and lithium resources located south of the Salton Sea in Imperial Valley along State Routes 111, 115, 86, and 78. These resources are critical to California’s clean energy future and are expected to drive significant industrial activity, workforce growth, and freight movement over the next decade.

The project supports the development of a sustainable and efficient multimodal transportation network that enables the movement of people, goods, and critical materials while reducing environmental and community impacts. It is intended to serve existing and planned geothermal facilities and lithium extraction operations and strengthen connections between communities, employment centers, industrial sites, border crossings, and regional markets.

This project is limited to planning and evaluating transportation improvements on state highways. It does not include the development or operation of lithium extraction or industrial facilities.

What We’re Doing in the PID Phase

The PID phase focuses on:

  • Supporting growth associated with Phase 1 of the Lithium Valley Specific Plan by identifying transportation needs related to lithium and geothermal development

  • Evaluating multimodal transportation improvements along State Routes 111, 115, 86, and 78, including highway, rail connectivity, transit, and active transportation

  • Assessing opportunities for freight and logistics efficiency, including access to industrial sites and regional markets

  • Exploring electric vehicle (EV) charging infrastructure for passenger and commercial vehicles

  • Identifying potential Intelligent Transportation Systems (ITS) improvements to enhance safety, operations, and reliability

  • Advancing sustainable and resilient infrastructure that supports clean energy, climate goals, and community needs

How We’re Engaging the Community

Caltrans is working closely with local agencies, regional partners, industry stakeholders, and the public to understand transportation needs and priorities.

We’re gathering input on:

  • How people and goods currently travel in the area

  • How future growth may impact these routes

  • Opportunities to improve freight movement, workforce access, and community connectivity

Your feedback will help guide planning and investment to support economic growth while maintaining safety, mobility, and community connections.
