Jibboom Street Bridge, Road and swing bridge over American River in Sacramento, United States.

The Jibboom Street Bridge is a road bridge spanning the American River in Sacramento, measuring about 290 meters long overall. The structure features a central movable span section and two steel truss approach ramps on either side.

The bridge opened on Easter Sunday, April 5, 1931, as the American River Bridge, replacing the old Natomas Trestle. Its central swing span came from the Webster Street Bridge between Oakland and Alameda, sold at auction to Sacramento County after the Posey Tube opened in 1928. The operator control house was removed by 1958, and the swing machinery was removed shortly after, closing the span to marine traffic.

The bridge stands as an example of early 20th-century engineering, demonstrating the metal rivet-connected Pratt through truss design common in that period.

The bridge sits near Discovery Park and currently handles light vehicular traffic. It serves as a place to explore early industrial engineering and view the river landscape.

The central swing span was barged from Antioch to Sacramento in March 1930, after being sold at auction when the Posey Tube opened. It had previously swung for ships between Oakland and Alameda, and was damaged in a January 1926 collision.
