State Route 99 Comprehensive Multimodal Corridor Plan
Description
Districts 3, 6, and 10, in partnership with Metropolitan Planning Organization (MPO) funding partners and stakeholders, collaborated on developing a long-range planning document—the Comprehensive Multimodal Corridor Plan (CMCP)—for State Route (SR) 99 through the Central Valley. The Caltrans districts partnered with a consultant team to develop and prepare the SR 99 CMCP.
The SR 99 CMCP builds on and updates the prior vision of past efforts, including the SR 99 Business Plan, while identifying a range of multimodal opportunities for improving and enhancing the SR 99 corridor and is aligned with statewide plans such as the California Transportation Agency’s Climate Action Plan for Transportation Infrastructure (CAPTI), the California Transportation Plan (CTP) 2050, and Caltrans System Investment Strategy (CSIS).
The SR 99 CMCP develops a shared vision and implementation plan for the SR 99 corridor that aligns with state goals and policies while meeting the needs of agency partners, stakeholders, and the traveling public. The CMCP addresses needs while analyzing impacts on all modes of transportation based on future land use growth along the corridor.
The CMCP study area's boundaries include the SR 99 corridor between the junction with Interstate 5 in the south and U.S. 50 in the north. The SR 99 CMCP was completed in November 2025 and is available below.
