Tower Bridge (California) 4.01

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 to east of Salt Lake City. The bridge is 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.In 1982, the Tower Bridge was added to the National Register of Historic Places.HistoryDeveloping the bridgeThe Tower Bridge replaced the 1911 M Street Bridge in Sacramento, which was originally a swing through-truss railroad bridge. Later, 9ft roadway sections were added as cantilevered sections on both sides of the existing rail bridge. Sacramento's population more than doubled between 1910 and 1935, rendering the existing bridge inadequate to handle heavy traffic. In 1933, the city realized that it needed a better crossing over the Sacramento River in case of war.
