California Invests $3 Billion to Enhance Safety, Improve Travel Times and Boost Multimodal Travel Options

San Diego, Ca — The California Transportation Commission (CTC) today approved $3 billion in allocations to enhance safety and mobility across the state highway system and expand multimodal travel, including bike lanes and pedestrian pathways. Guided by Governor Gavin Newsom’s Build More, Faster – For All infrastructure agenda, these improvements will make California communities safer, cleaner and increase access to active transportation options.

Of the $3 billion allocated this month, $663 million derives from Senate Bill (SB) 1, the Road Repair and Accountability Act of 2017 and approximately $2 billion from the federal Infrastructure Investment and Jobs Act of 2021 (IIJA). The funds will serve as a catalyst to increase the capacity of the state’s transportation system, rehabilitate aging roadways and improve travel times, while balancing community impacts and promoting environmental benefits.

“Today’s investments reflect California’s long-term commitment to safer roads, smarter traffic management and expanded transportation choices that get people where they need to go,” said Caltrans Director Dina El-Tawansy.

“The funds allocated today reflect the Commission’s commitment to investing taxpayer dollars strategically,” said CTC Chair Darnell Grisby. “These investments will improve the safety and reliability of the state’s transportation network and support a thriving economy by improving the movement of freight and reducing out-of-pocket expenses for all Californians.”

IIJA is a once-in-a-generation investment in our nation’s infrastructure to improve the sustainability and resiliency of our country’s energy, water, broadband and transportation systems. The total funding for California is nearly $54 billion. This includes investments to upgrade the state’s roads, bridges, rail, public transit, airports, ports, waterways and the electric vehicle charging network.

SB 1 has invested approximately $5 billion annually toward transportation projects since its adoption. It provides funding split between the state and local agencies. Road projects progress through construction phases more quickly based on the availability of funds, including projects that are partially funded by SB 1.
