Over $107 million for Contra Costa projects including $46.9 million on Hwy 4 improvements in East County, $42.4 billion on 680 in San Ramon Valley and $14.6 million on Caldecott Tunnel

In August, the California Transportation Commission (CTC) 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, $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.
The “…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…reflect the Commission’s commitment to investing taxpayer dollars strategically. 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 California,” said Darnell Grisby, Chair of the California Transportation Commission.
Projects in Contra Costa County approved by the Commission include:
- $46,900,000 on SR-4 in and near Antioch and Brentwood, from Hillcrest Avenue to Byron Highway, to rehabilitate pavement and drainage systems, upgrade facilities to ADA standards, install Accessible Pedestrian Signals (APS), high-visibility crosswalks, bike loop detectors, and construct Class II bike lanes. This will extend pavement service life and improve ride quality.
- $42,374,000 on I-680 in San Ramon and Danville, from Alcosta Boulevard to 0.1 mile north of Diablo Road, to rehabilitate pavement, upgrade guardrail, and upgrade facilities to ADA standards. This will extend pavement service life and improve ride quality.
- $14,584,000 on SR-24 in Orinda, at the Caldecott Tunnel, to rehabilitate and upgrade the ventilation system in Bores 1, 2, and 3. This will ensure structural integrity and prolong tunnel service life.
- $1,301,000 on SR-4 in Concord, 0.5 mile east of Port Chicago Highway, to reconstruct a failed slope embankment and repair a displaced down drain due to heavy rainfall in February and March 2025. Work includes installing Rock Slope Protection (RSP), and repairing the down drain, guardrail, and dike. This will enhance driver and pedestrian safety.
- • $1,275,000 on SR-4 near Pittsburg, 0.3 mile west of Bailey Road, to reconstruct a slope embankment and repair a displaced down drain due to heavy rainfall in February and March 2025. Work includes installing Rock Slope Protection (RSP). This will improve roadway safety.
- $999,000 on SR-24 in Lafayette, from 0.7 to 1.0 mile east of Acalanes Road, to rehabilitate pavement due to ponding and water seepage caused by heavy rainfall in February and March 2025, which led to cracking and settlement. This will extend pavement life and improve safety.
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 those partially funded by SB 1.
