The Tower Bridge
is a vertical lift bridge across the Sacramento River, linking West
Sacramento in Yolo County to the west, with the capital of California,
Sacramento, in Sacramento County to the east. It was previously a part
of U.S. Route 40 until that highway was truncated east of Salt Lake
City. The bridge is yet maintained by the California Department of
Transportation as part of State Route 275, and connects West Capitol
Avenue and Tower Bridge Gateway in West Sacramento with the Capitol
Mall in Sacramento.
