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.

The bridge opened on November 1, 1957, [10] connecting two peninsulas linked for decades by ferries. At the time, the bridge was formally dedicated as the "world's longest suspension bridge between anchorages", allowing a superlative comparison to the Golden Gate Bridge, which has a longer center span between towers, and the San Francisco–Oakland Bay Bridge, which has an anchorage in the middle.
The main span is the longest span without any ground support. Note : There is no standard way to measure the total length of a bridge. Some bridges are measured from the beginning of the entrance ramp to the end of the exit ramp.
Engineers spent weeks preparing to use explosives to break down the span, which was an estimated 500 feet (152 meters) long and weighs up to 600 tons (544 metric tons). The demolition was ...
With shore-to-shore lengths of 3.83 and 4.03 miles (6.16 and 6.49 km), [3] [22] the two spans of the bridge form the longest fixed water crossing in Maryland. [23] The bridge's western terminus is in Sandy Point State Park , located northeast of Annapolis in Anne Arundel County , and its eastern terminus is in Stevensville on Kent Island in ...
