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 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.
It spans the Straits of Mackinac, a body of water connecting Lake Michigan and Lake Huron, two of the Great Lakes. Opened in 1957, the 26,372-foot-long (4.995 mi; 8.038 km) [1] bridge is the world's 27th-longest main span and is the longest suspension bridge between anchorages in the Western Hemisphere. [5]

The bridge has a central span of 4,260 feet (1.30 km; 0.81 mi). It was the longest suspension bridge in the world until it was surpassed by the Humber Bridge in the UK in 1981. The bridge has the 18th-longest main span in the world, as well as the longest in the Americas.

This list of the longest arch bridge spans ranks the world's arch bridges by the length of their main span. The length of the main span is the most common way to rank bridges as it usually correlates with the engineering complexity involved in designing and constructing the bridge. [ 1 ]
