Location

The bridge opened on Easter Sunday, April 5, 1931.[2] Originally named the "American River Bridge," it allowed motorists to bypass the old Natomas Trestle, providing a more direct link to Sacramento from the Sacramento River Highway.[3] The bridge's main central swing span was originally built as part of the Webster Street Bridge, connecting Oakland and Alameda. That bridge had been recently reconstructed following a January 1926 ship collision with its central swing span.[4] Following the October 1928 opening of the Posey Tube, the Alameda County Board of Supervisors sold the Webster Street bridge at auction to Sacramento County.[5] In late December, 1928, workers disassembled the central swing span and floated it to Antioch by barge where it remained until March of 1930 when it was barged up the Delta to Sacramento.[6]

On August 18, 2018, Caltrans announced the indefinite closure of the Jibboom Street Bridge to both vehicles and pedestrians due to a maintenance report that revealed several critical structural elements in poor condition. The swing span was rotated into the open position on August 19 and subsequently locked open, therefore allowing marine traffic to pass through while the bridge was closed and no bridge tender was on duty. The bridge was reopened to a single lane of traffic with the swing span locked closed (not available for marine traffic) in October 2018, but was closed again in November following the discovery of more deficiencies.

The bridge remained closed throughout the winter of 2018-19 for a comprehensive rehabilitation project that addressed the deficiencies as well as engaged in preventive maintenance. The bridge fully reopened to traffic on April 2, 2019, and reopened to marine traffic usage the following day with a swing span opening and a police & fire boat passing through.
