Steelhead and steel bridges getting along swimmingly in CA

Carpinteria Creek Watershed Coalition is completing a multi-year Steelhead trout barrier removal project in partnership with South Coast Habitat Restoration and several private landowners. The Pinkham Ranch project eliminated one of the last major barriers with: the removal of nearly 100 feet of concrete-lined channel and stream banks; the disassembly and removal of an undersized bridge; the regrading of roughly 200 feet of channel and; the installation of a longer, clear-span Big R Bridge.

The picturesque bridge features naturally-weathering steel, a full-width treated timber wearing surface and a custom timber railing system, designed and furnished by the ranch owner.

Ten major barriers removed since 2001

The Carpinteria Creek Watershed Coalition has been working since 2001 to restore habitat for the federally endangered southern Steelhead trout in Santa Barbara County, California. This local community group made up of property owners, agency staff and non-profit partners has worked over the last several years to accomplish ten barrier removal projects in the watershed, opening up over four miles of important spawning and rearing habitat to these endangered fish.

Big R has been involved on several projects

As part of this effort a local non-profit, South Coast Habitat Restoration, has coordinated five projects on private property which have removed low-flow or Arizona crossings and replaced them with clear span Big R Bridges, such as the additional one shown here. These bridges provide safe access for the property owners, but also allow for the restoration of the stream channel and Steelhead migration corridor.
