The California Transportation Commission last week allocated more than $3.7 billion for projects to rebuild the state’s transportation infrastructure to enhance safety and create more convenient options for travelers.

More than $2.3 billion is from the federal Infrastructure Investment and Jobs Act of 2021, the bulk of which is going to over 600 cities, counties, and regional agencies to improve bridges, travel times and air quality; reduce planet-warming pollution; increase highway and rail safety; and provide transportation services. Nearly $169 million in funding is from Senate Bill (SB) 1, the Road Repair and Accountability Act of 2017.

“These investments will help California maintain and build a safer, more reliable and more climate-resilient transportation system,” said Caltrans Director Tony Tavares. “Commuters, bicyclists, pedestrians, and freight movers in local communities will all benefit as we continue to improve and rebuild our infrastructure.”

Projects the CTC approved include several in the Bay Area:

The IIJA, also known as the “Bipartisan Infrastructure Law,” is a once-in-a-generation investment in our nation's infrastructure to improve the sustainability and resiliency of our energy, water, broadband and transportation systems. California has received more than $22.6 billion since the IIJA’s passage in November 2021.

SB 1 provides $5 billion in transportation funding annually that is shared equally between the state and local agencies. Road projects progress through construction phases more quickly based on the availability of SB 1 funds, including projects that are partially funded by SB 1.
