Lane Closures on Bay Bridge and BART Yellow Line Delays: San Francisco Traffic Update for Jan 22, 2026

Morning Overview: Significant Activity on Major Arteries

Today, Thursday, January 22, 2026, commuters in San Francisco should prepare for a mix of scheduled maintenance and long-term project impacts affecting several primary routes. While the early morning rush is seeing typical volume, specific lane closures on the Bay Bridge and 19th Avenue will likely cause stacking during the midday and late morning hours.

Freeway Closures and Roadworks

The San Francisco-Oakland Bay Bridge is experiencing multiple maintenance layers today. Most notable for daytime travelers is the Caltrans Maintenance work on the Eastbound I-80 span. Lane 1, approaching the Yerba Buena Island Tunnel, is scheduled for closure between 7:00 a.m. and 2:00 p.m. This is expected to cause significant congestion for those heading toward the East Bay during the late morning. Additionally, the West Span Joint Rehabilitation project continues to impact overnight travel, though lanes are expected to be fully clear shortly after sunrise.

• 19th Avenue (SR-1): The ongoing paving and rehabilitation project continues between Lincoln Way and Holloway Avenue. Expect significant midday delays as crews work from 9:00 a.m. to 3:00 p.m. near San Francisco State University and Stonestown Galleria.
• US-101 and I-80 Viaducts: The Central and Bayshore project remains active. While morning ramps are open, the Westbound Harrison and 7th Street on-ramp is scheduled for closure again tonight starting at 11:00 p.m. and lasting until tomorrow morning.

Public Transit Alerts

Public transit riders should allow for extra travel time today, particularly on the BART Yellow Line. Track maintenance has necessitated single-tracking between the North Concord and Pittsburg/Bay Point stations. These works are expected to cause delays of 20 to 25 minutes for commuters throughout the day and evening.

• SFO/Millbrae Delays: For those traveling to San Francisco International Airport, train control modernization work will result in 30-minute delays for trains operating after 9:00 p.m.
• New Transit Integration: Commuters are reminded that as of this week, the BART mobile app now features integrated ride-hailing services, which may provide a convenient alternative for those affected by the current trackwork delays or station modernization projects.

Weekend Planning

Looking ahead, residents should prepare for significant downtown disruptions this coming Saturday, January 24. The annual Walk for Life West Coast rally will result in the closure of Market Street from Civic Center to Embarcadero Plaza between 9:00 a.m. and 6:00 p.m., affecting nearly 20 Muni lines, including the 5 Fulton, 14 Mission, and 38 Geary.
