Invisible-5 is a self-guided critical audio tour along Interstate 5 between San Francisco and Los Angeles. It uses the format of a museum audio tour to guide the listener along the highway landscape. Invisible-5 investigates the stories of people and communities fighting for environmental justice along the I-5 corridor, through oral histories, field recordings, found sound, recorded music, and archival audio documents. The project also traces natural, social, and economic histories along the route. Sites along the tour, which can be driven in either direction, include Livermore, Crows Landing, Kesterson NWR, Kettleman City, and Boyle Heights in East Los Angeles. The entire free, downloadable program in MP3 format with a printable PDF booklet is available at

Invisible-5 was produced as a collaboratively between three artists and two organizations; artists, Amy Balkin and Kim Stringfellow; audio lead, Tim Halbur; and non-profit organizations, Greenaction for Health and Environmental Justice, and Pond: Art, Activism, and Ideas. The project was supported through a grant from the Creative Work Fund. This project was featured on NPR’s regional news program “The California Report” produced by Bay area NPR affiliate, KQED.
