I Street Bridge

The I Street Bridge is a historic metal truss swing bridge which crosses the Sacramento River to link the capital city of Sacramento, California, with Yolo County to the west. Built in 1911, this historic bridge has a vertical clearance of 14 feet 8 inches and was originally part of State Route 16. It also carries two walkways; one on either side of the roadway.

The lower level of the bridge provides rail access to Sacramento from points south and west; the upper level provides highway access.

It was built to replace an 1867 timber Howe truss swing span bridge, which also carried both railroad and road traffic.
