UPDATE ON CURRENT AND FUTURE CONSTRUCTION PROJECTS

🦺 I-80/Gilman Interchange Project

Where: Gilman Street in Berkeley

When: On Schedule to be completed by April 2025

Why: The wait is almost over! By next month, the I-80/Gilman Interchange project will be complete, delivering major upgrades for traffic flow, safety, and accessibility. The new roundabouts will reduce congestion and shorten queues, while new bike and pedestrian paths—including an overcrossing and Bay Trail connection—will make it safer for non-drivers. After months of work, these improvements will soon transform the way people move through the area, making commutes and waterfront access easier and more efficient for everyone.

🦺 I-680 Paving Project

Where: Between Sunol and San Ramon

When: On Scheduled to be Completed Spring 2027

Why: The I-680 Paving Project is bringing long-term roadway improvements to one of the region’s busiest corridors. By repaving worn-out sections and upgrading key infrastructure, this project will reduce vehicle wear and tear, improve traffic flow, and enhance overall safety. Construction activities, including paving and drainage improvements, are underway with both daytime and nighttime work. When complete, travelers can look forward to a smoother and more reliable driving experience along I-680.

🦺 Alameda County I-880 Capital Preventive Maintenance

Where: Between Fremont Blvd and the Alameda County/Santa Clara County line.

When: Work commenced in October 2023, with an expected completion by late 2025.
Due to seasonal weather conditions, paving activities are on hold and will restart in April 2025.

Why: The project focuses on extending pavement life and improving ride quality along this vital stretch of I-880. Key upgrades involve replacing asphalt surfacing, bringing curb ramps up to ADA standards, enhancing pedestrian crossings with flashing beacons, and updating traffic systems and signage. Overnight lane closures are in place to facilitate the work while reducing daytime traffic impacts.

🦺 Oakland Alameda Access Project

Where: I-880/I-980 and the Posey and Webster Tubes, spanning parts of Oakland’s Chinatown, Jack London District, and the City of Alameda.

When: Construction is scheduled to begin in Summer 2025

Why: This project is designed to improve traffic flow, enhance safety, and create better connections between Oakland and Alameda. By reducing freeway-bound traffic in residential areas, adding safer pedestrian and bicycle paths, and reconfiguring freeway ramps, it will make travel smoother and safer for all road users.

🦺 I-680/I-580/I-238 Rehabilitation Project

Where: Between I-680/I-580 Interchange in Pleasanton to I-580/I-238 Interchange in Castro Valley

When: Construction began Winter 2024

Why: This project aims to address safety concerns, improve ride quality, and extend the service life of the pavement. Key activities include replacing concrete slabs, constructing concrete barriers, and upgrading infrastructure to current standards. These improvements will enhance the overall driving experience and ensure long-term durability of the roadway.

🦺 I-680/I-238 Mission Blvd Bridge Deck Rehab project

Where: I-680/I-238 separation in Fremont

When: Currently in the planning phase

Why: This rehabilitation project aims to enhance safety, reliability, and longevity for this section of I-680. Work includes repairing the bridge deck, replacing joints, and upgrading approach slabs. These improvements will extend the life of the bridge, improve ride quality, and maintain a safe transportation network for all travelers.

🦺 Vision 980 Study

Where: All of Interstate 980 in West Oakland

When: The Vision 980 Study is currently underway, with community engagement and planning efforts shaping the future of the corridor.

Why: Built through racially discriminatory policies and redlining, I-980 displaced families, divided communities, and contributed to economic disinvestment. Today, the freeway is seen as a barrier to mobility and opportunity. This study aims to reimagine the corridor through a community-driven process, exploring possibilities such as new housing, business opportunities, open space, public transit connections, and safer pedestrian and bike access.

A Driver’s Best Resource on the Highway

Navigating the highways in the Bay Area has it’s challenges. The highways in San Mateo County are no exception. Whether you're commuting to and from the Silicon Valley or making your way towards San Francisco for an eventful outing. We have all experience the impact of busy highways. A great resource for motorists is QuickMap. It is both a mobile app and a website (quickmap.dot.ca.gov) that provides real time traffic information, including road conditions, facility information and resources for commercial vehicles. A highlight for motorists is the ability to see what lane closures and/or traffic incidents may be along your route. The detailed information allows motorists to make informed decisions as they travel the highways. The listed lane closures provide start and stop times of closures and the listed traffic incidents provide additional information such as which lane the accident ahead is in. This type of information can assist motorists in lessening delays. Please consider checking QuickMap before you drive.
