Major BART Disruptions and I-80 Lane Closures Impacting Monday Commute

Commuter Alert: BART Transbay Service and Highway Roadworks

Good morning, Oakland. It is Monday, February 23, 2026. Commuters are facing a challenging start to the week as transit officials work to restore full service on BART following significant weekend disruptions, while several major highway projects continue to impact regional travel across the East Bay.

BART Service Uncertainties and Station Closures

The primary concern for Monday morning is the ongoing recovery of BART service through the Transbay Tube. Late Sunday night, service was halted between San Francisco and the East Bay due to a loss of communications caused by damaged cables near the West Oakland station. While repair crews have been working through the night to restore functionality for the Monday morning commute, riders should prepare for residual delays and potential trip cancellations. If service is not fully restored by the peak hour, AC Transit will continue to provide bus bridges between the Salesforce Transit Center in San Francisco and various East Bay locations using the F, O, and N/L lines.

Additionally, riders at the 19th St./Oakland station should be aware that the entrance located at the northwest corner of Broadway and 17th Street is officially closed starting today. This closure is expected to last for approximately two weeks while workers remove damaged artwork from the entrance walls. Commuters are encouraged to use the nearby elevator or alternative station entrances along Broadway during this period.

Highway Delays and Major Construction Projects

Motorists traveling on major arteries including I-80 and CA-24 will encounter several active work zones today:

• I-80 Bay Bridge: The 4th Street off-ramp in San Francisco, which has been closed for a rehabilitation project throughout the weekend, is scheduled to reopen at 6:00 a.m. today. Commuters should expect heavy merging traffic as the ramp returns to service.
• Caldecott Tunnel: Caltrans has scheduled overnight closures for select bores of the Caldecott Tunnel on CA-24. While all bores are expected to be available for the heart of the morning commute, late-night and early-morning travelers may encounter detours.
• Carquinez Bridge: Ongoing lane closures are in effect on the Carquinez Bridge from 3:00 a.m. to 1:00 p.m. this Monday. This work is part of a long-term maintenance project and is expected to cause significant slowing for northbound commuters.
• I-80 Corridor: Overnight ramp and lane closures between Albany and Hercules are ongoing. While work usually wraps up by 5:00 a.m., early commuters should remain alert for lingering equipment and merge shifts.

AC Transit and Local Stop Adjustments

Local bus riders should note specific service changes taking effect today. Lines 604 and E are experiencing temporary stop closures at Tunnel Rd and Domingo Ave between 8:00 a.m. and 4:00 p.m. due to local construction. Furthermore, commuters are reminded that AC Transit is now operating under the "Realign" network schedules launched earlier this month. Most routes have seen minor schedule adjustments to account for changing traffic conditions on I-80. Residents are advised to leave early and double-check their specific lines for any time-table shifts.
