Boulder County Awarded $25M Federal Grant for CO 119 Safety and Mobility Improvements Project!

Boulder County has been awarded a $25M Rebuilding American Infrastructure with Sustainability and Equity (RAISE) Grant for the CO 119 Safety and Mobility Improvements Project. Boulder county and all of the CO 119 project partners, including CDOT, RTD, City of Longmont, City of Boulder and Commuting Solutions are thrilled to receive this news. CO 119 is the top priority regional corridor project from the Northwest Area Mobility Study supported by the Northwest Mayors and Commissioners Coalition. Boulder County and our project partners are very appreciative of the USDOT awarding this funding and the on-going support over many years from Colorado’s congressional delegation, including Congressman Joe Neguse as well as Senator Bennet and Senator Hickenlooper.

“This grant will help to accommodate our state’s growing population as we work to develop a safer, more reliable transportation corridor between two of the fastest growing cities in Colorado—Boulder and Longmont,” said Congressman Neguse. “For years we’ve heard of the importance of improving mobility between these communities, and I am thrilled to see our hard work and collaboration come to fruition.”

“The Bipartisan Infrastructure Law is the most significant investment in America’s roads, bridges, and essential infrastructure since President Eisenhower built the interstate highway system. This funding for the Diagonal Highway Project will help reduce congestion and improve air quality along one of the busiest roads in Boulder County, and I commend all the project partners for their vision and hard work,” said Senator Bennet. “I urged the Department of Transportation to fund this project, and I will make sure that our state continues to benefit from this historic law.”

The RAISE grant provides a critical piece of the funding puzzle critical piece of the funding puzzle for the CO 119 Safety and Mobility Improvements Project along the Diagonal connecting Boulder and Longmont. The project will implement improved regional transit, Park-n-Ride locations, a commuter bikeway and intersection safety improvements. Together these improvements will provide greater transportation options and safety for people using all modes of travel while supporting our regional mobility and transportation goals. With this final piece of funding, the corridor reconstruction project can begin in 2024.
