The future calls and CCTA is ready! On September 20th, the Board adopted the 2017 Countywide Comprehensive Transportation Plan (CTP), and proudly released it as our solid framework for transportation investments for 10-year and 20-year milestones. This edition of the CTP builds on plans and policies established with the passage of Measure C in 1988 and then renewed in 2004 with Measure J.

The 2017 CTP has been crafted to improve transportation for all members of the community, at all times of the day. CCTA aims to connect people with their desired modes of travel so they can get where they need to go safely, efficiently, and cost-effectively. More broadly, we hope to connect our communities through an effective transportation network that is cutting-edge, convenient, and user-friendly.

Countywide Transportation Plan 2017 Update


The Countywide Transportation Plan (CTP) provides the overall direction for achieving and maintaining a balanced and functional transportation system within Contra Costa while strengthening links between land use decisions and transportation. The CTP outlines the Contra Costa Transportation Authority’s vision for Contra Costa and establishes goals, strategies, projects, and actions for achieving that vision.

2017 Countywide CTP Summary

What’s Next?

With the final CTP adopted, we are now working on implementing the calls to action that our stakeholders and constituents asked us to undertake. The major projects include:

  • New BART extension proposed from Antioch to Brentwood along with technology upgrades to enable BART and transit providers to better coordinate schedules, improve station access and amenities, and even optimize pricing to increase ridership
  • Update the Countywide Bicycle and Pedestrian Plan
  • Innovate I-680, which includes a suite of new features to improve the travel experience, such as:
    • Increased High-Occupancy Vehicle (HOV) access
    • Express Bus lanes on the highway shoulders to bypass congested traffic
    • Intelligent Transportation System (ITS) technology to communicate information between vehicles and roadway management equipment
  • Explore the role of autonomous vehicles and the infrastructure needed to support this new technology
  • Interstate-80/State Route 4 connectivity improvements
  • New transit options in West County such as express bus improvements in the I-80 Corridor and bus rapid transit upgrades on San Pablo Avenue
  • Iron Horse Trail safety improvements at street intersections

In addition, the CTP plans for local and regional street improvements throughout the County.

Historically, congestion in Contra Costa County has followed regional job growth and losses. Current job and housing forecasts through 2040 indicate the level of congestion will continue to increase throughout the next 23 years.

Achieving the Plan’s Goals

CCTA Planning Transportation funds infographicThe 2017 Countywide Transportation Plan will play an important role in shaping our transportation policy and investment decisions. Currently about $3.7 billion in project funding has been identified, which is not enough to meet Countywide transportation needs over the next 23 years. The Plan outlines the strategies that will be essential for a smooth transition from vision to reality.

The Authority will need to work with many public and private sector partners to leverage the funds needed to achieve the CTP goals to:
