What is a Comprehensive Multimodal Corridor Plan?

The State Route 70-99 Comprehensive Multimodal Corridor Plan (SR 70-99 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. 

The SR 70-99 CMCP will align with the following priorities:

  • Include local, regional and state agencies in the corridor planning process
  • Balance infrastructure, livability, economic and sustainability
Provide multimodal, multidisciplinary corridor-based planning

This effort will develop a comprehensive multimodal corridor plan and concept of operations addressing regional and interregional safety, congestion, accessibility, goods movement, economic development, land use efficiency, public health, air quality, and greenhouse gas emissions for State Routes 70, 99 and 149 (SR 70, SR 99, SR 149) in Butte, Sacramento, Sutter and Yuba counties. The final product will be developed in collaboration with local agency partners and stakeholders. The plan will provide a range of proposed concepts, evaluate and prioritize improvements within the study limits, and set a solid framework for implementing short- and long-term capital improvements supporting the Road Repair and Accountability Act of 2017 (SB 1) goals and priorities.
