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:

Caltrans District 4 is conducting the Interstate (I) 580 Truck Access Study (TAS) to answer the following question: How would removing the truck weight restriction (aka truck ban) on I-580 affect safety, efficiency, reliability, and traffic speed along the I-880 and I-580 corridors, and how would this change impact public health equity for nearby communities?

Purpose

Answering this question will create an opportunity to reevaluate the purpose of the truck ban, find consensus for its future status, address existing issues of inefficient traffic flows for impacted communities and the freight industry, and alleviate disproportionate health impacts for underserved communities of color within the study area.

Caltrans District 4 has partnered with the Bay Area Air District and the City of Oakland to complete this study. Other TAC members include:

  • Metropolitan Transportation Commission (MTC)
  • California Highway Patrol (CHP)
  • Port of Oakland
  • Alameda County Transportation Commission
  • Alameda County Public Health Department
  • AC Transit
  • City of Oakland
  • City of Emeryville
  • City of Piedmont
  • City of Alameda
  • City of Berkeley
  • City of San Leandro
  • West Oakland Environmental Indicators Project (WOEIP)
  • Communities for a Better Environment (CBE)
  • San Leandro 2050
  • California Trucking Association
