The Solano Transportation Authority and the city of Rio Vista have been exploring alternatives for improving long-term transportation mobility on State Route 12 through Rio Vista and across the Sacramento River. The existing Sacramento River Crossing at Rio Vista is a lift bridge that completes a vital link between Interstate 80 and Interstate 5.
The project team is investigating the existing route as well as routes north and south of the airport and a southern corridor along the river bluffs. Operation of the lift bridge causes frequent traffic delays. As the community grows and regional traffic increases, the delays are expected to worsen. Replacement of the lift bridge will eliminate traffic back-ups associated with existing bridge operations.
