Nightly Ramp Closures and Howard Street Construction Drive Thursday Delays

Commute Overview for Thursday, February 26, 2026

Commuters in San Francisco should prepare for a mix of daytime lane closures and significant late-night ramp restrictions today. While the morning rush is expected to flow relatively well on major freeways, ongoing multi-year infrastructure projects in the SoMa and Richmond districts continue to necessitate detours and stop relocations. Drivers and transit riders are encouraged to allow an extra 15 to 20 minutes of travel time, particularly during the afternoon peak.

Major Roadworks and Ramp Closures

The San Francisco-Oakland Bay Bridge Joint Rehabilitation Project remains a primary focus for nighttime travelers. Starting tonight at 10:00 p.m. and continuing until 7:00 a.m. Friday, several critical ramps will be closed for maintenance. Motorists should plan for the following impacts:

• Eastbound I-80: The off-ramp at 7th and Bryant streets will be closed.
• Westbound I-80: The on-ramps at both 7th and Harrison streets and 4th and Harrison streets will be inaccessible.

In the downtown core, the Transbay Howard Streetscape Project is in full swing. Expect intermittent lane closures and delays on Howard Street between The Embarcadero and 4th Street from 7:00 a.m. to 4:00 p.m. This work includes new safety upgrades and traffic signal infrastructure. Additionally, the Main Street Improvements Project continues to affect the stretch between Market and Howard streets, reducing capacity for those heading toward the Financial District.

Public Transport and Rail Alerts

BART is advising passengers of ongoing train control modernization work. While daytime service is largely unaffected, riders traveling between Millbrae and SFO after 9:00 p.m. tonight should anticipate delays of up to 30 minutes. Furthermore, BART has issued a reminder regarding Clipper card upgrades; riders using station vending machines must hold their cards against the reader throughout the entire transaction rather than tapping.

Caltrain service is operating on its new electrified schedule, with full service restored to the Tamien Station as of earlier this month. However, regional travelers using the Capitol Corridor should note that reduced train service remains in effect through tomorrow, February 27, due to equipment unavailability. Several trains, including 520, 526, and 537, have been canceled for the day.

Neighborhood Impact and Transit Changes

In the Richmond District, sewer and water line replacement continues along Geary Boulevard between 32nd Avenue and Stanyan Street. Riders of the 38 Geary and 38R Geary Rapid should look for orange signage as several bus stops have been temporarily relocated. On the west side, Caltrans is preparing for Phase 2 of the 19th Avenue Rehabilitation Project, which will involve full lane repaving from Holloway Avenue to Lincoln Way starting this spring. While all lanes remain open today, expect increased worker activity and signage in the area.
