A museum dedicated to the history and role of dredging in the Sacramento River Delta, and the role of the Dutra Family in that process.
The Helen Madere Memorial Bridge, commonly called by its former name, the Rio Vista Bridge after its location, is a vertical-lift bridge which carries California State Route 12 across the Sacramento River at Rio Vista. The present bridge was completed in 1960 and is one of several moveable bridges spanning rivers in the Sacramento–San Joaquin River Delta.
