Boulder County’s Transportation Master Plan (TMP), adopted in 2020, is a 25-year, multimodal vision for developing a safe, accessible, and sustainable transportation system that connects people and places efficiently and environmentally responsibly. It focuses on improving road, trail, transit, and pedestrian networks, creating better access, and providing a range of travel options to meet current and future needs. The TMP is supported by the Countywide Transportation Sales Tax and guides investments and programs for infrastructure, maintenance, and new transportation services. Key strategies, based on the Boulder County Comprehensive Plan, include developing a multimodal system, creating complete trips, investing in key corridors, increasing accessibility, and enhancing mountain area connections.
Transportation Master Plan (TMP)
TMP Report on Progress
In Spring 2026, Boulder County released a Report on Progress documenting the county’s accomplishments since the adoption of the TMP and outlining priorities for continued investment in a safe, sustainable, and accessible multimodal transportation system.
The report evaluates implementation of the plan during a period marked by changing travel patterns, housing affordability challenges, economic pressures, and rising construction costs. Despite these challenges, the county has continued advancing transportation projects and programs that improve safety, expand travel choices, strengthen regional connections, and increase equitable access to transportation. The report also demonstrates how the Transportation Master Plan continues to align with the Board of County Commissioners’ strategic priorities for climate action, economic security, and good governance.
The report highlights progress in each of the Transportation Master Plan’s five strategies and seven performance metrics and includes recommendations for next steps:
- Cap Vehicle Miles Traveled (VMT) per Capita – Vehicle miles traveled (VMT) per capita remains on track toward the county’s goal, with 2023 levels approximately 13% below the 2005 baseline. While changes in remote work have helped reduce driving, future travel patterns will continue to evolve.
- Increase Transit Ridership – Transit ridership continues to recover from significant pandemic-related declines but remains below pre-2020 levels. As travel patterns continue to shift, Boulder County is developing the Linking Boulder County strategic transit plan to strengthen transit governance, improve service coordination, and support long-term ridership growth.
- Eliminate Serious Injury and Fatal Traffic Crashes – Following a temporary decline during the pandemic, crashes increased as travel resumed. Adoption of the county’s Vision Zero Action Plan in 2025 establishes a roadmap for achieving zero serious injuries and fatalities by 2035 through targeted safety investments and roadway improvements.
- Maintain County Roads – the county continues to maintain its most heavily traveled roads, but pavement conditions on local and subdivision roads remain a challenge due to limited funding. Maintaining roadway conditions over the long term will require increased and more stable investment to address resurfacing and rehabilitation needs.
- Maintain County Bridges – The county’s bridge network remains in generally good condition, with nearly all major structures rated in fair or good condition. Ongoing inspections and targeted investments will focus on repairing the single structure in poor condition while extending the service life of other bridges.
- Complete the Bike Vision Network – Steady progress continues toward completing the regional Bike Vision Network, with the planned network advancing into planning, design, and/or construction. Major projects such as the CO 119 Bikeway, North Foothills Bikeway, and the Boulder to Erie Regional Trail (BERT) will continue expanding safe, low-stress bicycle connections throughout the county. Additional funding is needed to achieve the full Bike Vision Network.
- Affordable Living – Boulder County has met its goal of providing affordable transit access for housing authority residents and voucher holders through expanded EcoPass programs and discounted fare initiatives. Future efforts will focus on expanding these programs and increasing awareness so more residents can take advantage of affordable transportation options.
