Caltrans advances study on lifting semi truck ban on I-580

California transportation officials are moving ahead with a study to determine the impacts of lifting the ban on commercial trucks on I-580 in the Bay Area.

This month, Caltrans is hosting two in-person listening sessions to allow interested residents to share concerns about lifting the truck ban on the I-580 corridor in the Oakland area.

The listening sessions are part of the I-580 Truck Access Study (TAS), which will look into the ways that repealing the truck ban could impact safety, traffic congestion, pollution, and public health along along the I-880 and I-580 corridors.

Many truckers use I-880 as an alternative to I-580.

“This study will create an opportunity to better understand how and why trucks travel through the study area, determine if the ban should be repealed, and identify strategies that could help alleviate disproportionate health impacts from truck traffic experienced by communities within the study area,” Caltrans said.

A final report is expected in late 2026 or early 2027.

The I-580 TAS is also considering “existing issues of inefficient traffic flows for the logistics industry.”

For decades, vehicles weighing more than 9,000 pounds have been prohibited from using I-580 between Foothill Boulevard in San Leandro and Grand Avenue in Oakland. Trucks that violate the ban are subject to enforcement.

Caltrans is conducting the study in partnership with the Bay Area Air District and the City of Oakland.
