Rio Vista Bridge

Rio Vista Bridge is a vertical-lift bridge carrying State Route 12 across the Sacramento River with substantial overall length. Its central span raises vertically to permit vessels to pass through with clearance reaching about 135 feet.

The current bridge was completed in 1960, replacing an earlier bascule bridge from 1919 that had served the river crossing. The new design earned recognition from the American Institute of Steel Construction for its engineering.

The bridge carries the name Helen Madere Memorial Bridge in honor of a former Rio Vista vice-mayor who championed traffic safety improvements on California State Route 12. Local residents often mention this connection when talking about community leaders who left their mark on the town.

The bridge operates daily for road traffic and raises as needed for large vessels, which means brief waiting periods are possible. Best to drive attentively during peak hours and note that pedestrians and cyclists have designated areas.

In 1967, the Italian freighter Ilice collided with the raised span, destroying an entire truss section. Emergency repairs were completed within three weeks, showing the structural resilience of the design.
