The first train had crossed the bridge on November 7, 1935. [6] The Tower Bridge was the first vertical lift bridge in the California Highway System after it was formally accepted by the state on January 11, 1936. [6] The final trains ran over the bridge in 1962, [9] and the railroad tracks were removed the following year. [6]
Tower Bridge is a Grade I listed combined bascule, suspension, and, until 1960, ... "The total length of the bridge, including the abutments, is 940 feet, and the ...
Since 1996, the highway has been legally defined to be the length of the Tower Bridge crossing the Sacramento River. Prior to that year, SR 275 was also known as the West Sacramento Freeway, and was a short spur connecting Interstate 80 Business / U.S. Route 50 in West Sacramento, and the Tower Bridge.
This list of tallest bridges includes bridges with a structural height of at least 200 metres (660 ft). The structural height of a bridge is the maximum vertical distance from the uppermost part of a bridge, such as the top of a bridge tower, to the lowermost exposed part of the bridge, where its piers, towers, or mast pylons emerge from the surface of the ground or water.
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.

Finished in 1894, Tower Bridge was the largest and most sophisticated bascule bridge ever completed
The definition of cable-stayed bridge deck length used here is: A continuous part of the bridge deck that is supported only by stay-cables and pylons, or are free spans. This means that columns supporting the side span as for example found in Pont de Normandie , excludes most of the side span decks from the cable-stayed deck length.
Some bridges are measured from the beginning of the entrance ramp to the end of the exit ramp. Some are measured from shoreline to shoreline. Yet others use the length of the total construction involved in building the bridge. Since there is no standard, no ranking of a bridge should be assumed because of its position in the list.
