State Route 49 Comprehensive Multimodal Corridor Plan

Logo for State Route 49 Comprehensive Multimodal Corridor Plan


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 Route 49 (SR 49) in Nevada and Placer 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.

What is a Comprehensive Multimodal Corridor Plan?

The SR 49 Comprehensive Multimodal Corridor Plan (CMCP) is based on the California Transportation Commission’s 2018 Comprehensive Multimodal Corridor Plan Guidelines. This guidance emphasizes a holistic planning approach that strives to achieve a balanced transportation system. In following with the Guidelines, the SR 49 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
