Study Area Map:

Map of the Study Area, encompassing parts or the full extents of Oakland, Berkeley, Emeryville, Piedmont, Alameda, San Leandro, and parts of unincorporated Alameda County. The I-580 truck ban segment of the highway is highlighted in orange.

 

Overview:

The Department of Transportation (Caltrans), District 4 is conducting the Interstate (I) 580 Truck Access Study (TAS) to understand how removing the truck ban on I-580 could affect safety, travel patterns, traffic conditions, air quality, and noise along the I-880 and I-580 corridors and other nearby state highways and major arterials. The study will evaluate how exposure to air and noise pollution could change for nearby communities if the truck ban is removed. 

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an opportunity to better understand how and why trucks travel through the study area, determine if the ban should be repealed, and identify strategies that could help alleviate disproportionate health impacts from truck traffic experienced by communities within the study area. 

Your Voice Matters!

Caltrans will work to gather input from community members throughout this important study process. Your input is critical to ensuring that community voices and lived experiences help shape the study's goals and outcomes.
