Rio Vista Bridge, Vertical-lift bridge in Rio Vista, California
The Rio Vista Bridge extends 2,890 feet across the Sacramento River with a central vertical lift span measuring 306 feet in length.
The current structure, completed in 1960, replaced a 1919 bascule bridge and received recognition from the American Institute of Steel Construction upon completion.
The bridge bears the name Helen Madere Memorial Bridge, honoring the former Rio Vista vice-mayor who worked to improve safety on California State Route 12.
The bridge connects State Route 12 over the Sacramento River and lifts to provide clearance up to 135 feet for maritime vessels passing underneath.
In 1967, the Italian freighter Ilice collided with the raised bridge, destroying an entire truss span, leading to emergency repairs within three weeks.
