BART ridership surges amidst I-80 closure this weekend

BART saw significant ridership increases across the system from Friday through Sunday as sunny weather and a weekend-long closure of a stretch of Interstate 80 in San Francisco prompted thousands of people to turn to transit as a reliable alternative. The sharp increases underscore BART's critical role in keeping the region moving when major infrastructure is out of commission.

On Friday, April 17, BART recorded 182,570 trips, a 16% increase compared to the previous Friday, with nearly 25,000 additional riders. Growth accelerated over the weekend, with Saturday, April 18, reaching 139,700 trips - up 46% week over week - and Sunday, April 19, totaling 98,850 trips, a 46% increase over the prior Sunday. The increases were also bolstered by warm weekend weather; the previous weekend was rainy, which typically decreases BART ridership.

April ridership to date is about 10% higher than a year ago, continuing an overall upward trend. March broke multiple post-pandemic ridership records.

BART as a backbone during disruptions

The weekend's ridership surge highlights how BART serves as essential infrastructure for the Bay Area, not only for daily commutes and events, but also during unexpected or planned disruptions to the region's transportation network.

When major roadways like I-80 are unavailable, BART provides a high-capacity, reliable alternative that can quickly absorb increased demand. The system's ability to accommodate tens of thousands of additional riders in a single weekend demonstrates its importance to the region's mobility and resilience. BART had the capacity to accommodate this increase in ridership while running standard 5-line weekend service.

BART will continue to play a vital role in supporting the Bay Area during major events, infrastructure projects, and other moments when reliable transit is needed most.
