Santa Margarita River Fish Passage and Bridge Replacement

This project replaced a low-flow river crossing at Sandia Creek Drive — the last remaining fish passage barrier on the mainstem Santa Margarita River — with a full-span bridge to restore migration access for endangered Southern California steelhead, opening 12 miles of upstream spawning and rearing habitat approximately two miles north of Fallbrook in San Diego County.
