View of the Garvey Bridge over the Rio Hondo, showing the underpass from the equestrian trail in Rosemead. The Rio Hondo is a 20 mile tributary of the Los Angeles River, which passes through several cities in Los Angeles County. As seen here, most of the river flows in a concrete-lined channel to serve a flood control function, but in two places the river does not flow over conrete, the Peck Road Water Conservation Park and the Whittier Narrows Recreation Area.
