Interstate 80 Comprehensive Multimodal Corridor Plan

What is a Comprehensive Multimodal Corridor Plan?

The Interstate 80 Comprehensive Multimodal Corridor Plan (I-80 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-80 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-80 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.

Caltrans District 3 (Sacramento Region) and District 4 (Bay Area Region) have partnered on this joint CMCP effort for the I-80 corridor to better understand the issues on the corridor and to plan appropriately.

The I-80 CMCP incorporates approximately 70-miles of the I-80 corridor — from the Carquinez Bridge in Solano County, through Yolo County and ending in Sacramento County at the junction with SR 51, including a short segment of US 50 between I-80 and I-5.
