What is a Comprehensive Multimodal Corridor Plan?

The Interstate 5 Comprehensive Multimodal Corridor Plan (I-5 CMCP) is based on the California Transportation Commission’s 2018 Comprehensive Multimodal Corridor Plan Guidelines. This guidance emphasizes a planning approach that strives to achieve a balanced transportation system.

Caltrans is preparing the I-5 CMCP, a long-range comprehensive planning document, with the goal of achieving a more balanced transportation system that addresses community and environmental impacts.

The I-5 CMCP will evaluate the existing transportation conditions of the corridor and proposes mitigation measures to address factors such as congestion, safety, environmental, and multimodal transportation. The CMCP will analyze impacts to all modes of transportation based on future land use growth along the corridor. Modes of transportation analyzed in the CMCP includes passenger rail, freight rail, local and express bus routes, and bicycle and pedestrian facilities. It will identify and prioritize potential improvements that address all modes of transportation on the corridor.

The CMCP will facilitate and allow collaboration between Caltrans, local and regional partners to apply to regional, state, and federal funding programs.

The I-5 CMCP incorporates the complete I-5 corridor in Sacramento county and a portion of Yolo county, ending at the State Route 16 junction outside of the City of Woodland
