RIO VISTA (CBS SF) — The Antioch Bridge and State Route 160 have reopened after an injury accident involving two semi-trucks forced the span to be shut down for hours Monday, according to CHP.

The Solano County Fire Department was contacted to request support and an air ambulance. Rio Vista police and fire also responded to the scene.
