Interstate 580 Truck Access Study (TAS) Background
This study originated from the Bay Area Air District’s adoption of the West Oakland Community Action Plan (WOCAP) (2019). The WOCAP identified numerous strategies including one strategy to examine the effects of removing the truck ban on Interstate (I) 580. In response to community needs Caltrans District 4 secured State Planning and Research grant funding to develop and implement the study.
On March 24, 2025, Caltrans District 4 kicked off the I-580 TAS with the Bay Area Air District and the City of Oakland as study partners. The I-580 TAS will reexamine the long-standing truck weight ban along the I-580 corridor which begins at Foothill Boulevard in the City of San Leandro and ends at Grand Avenue in the City of Oakland. The study area also includes the parallel segment of I-880, other State highways, major arterials, and neighboring cities such as Piedmont, Berkeley, and San Leandro, as well as unincorporated communities in Alameda County, that may be impacted if the ban was lifted.
The study will be completed in late 2026/early 2027.
The study scope has been divided into four components including: Traffic Studies, Air Quality and Noise Impact Assessment, a Racial Equity Assessment, and a Comprehensive Community Engagement Strategy to guide public engagement through the duration of the study. The study scope includes a near future scenario with the truck ban in place and a scenario with the ban removed. The Air Quality Assessment will be led by the Air District and the Racial Equity Assessment will be modeled after the City of Oakland.
Caltrans District 4 will be hosting the first public engagement event on November 12, 2025, from 6:30 PM - 8:00 PM. This initial public engagement event for the I-580 TAS will be virtual and hosted via Zoom. The meeting will be part presentation and feature a facilitated question and answer period.
Registration is not required for the event, and the Zoom link is posted on the I580 TAS study website. Members of the public can also sign up for study announcements and updates on the study via the Constant Contact link, I580 TAS Constant Contact Landing Page.
