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 Sagar Iron Suspension Bridge with a 200 feet span (also termed Beose Bridge) was constructed near Sagar, India during 1828–1830 by Duncan Presgrave, Mint and Assay Master. [15] The Clifton Suspension Bridge (designed in 1831, completed in 1864 with a 214 m central span), is similar to the Sagar bridge. It is one of the longest of the ...

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.
The length of the bridge's main span is 3,800 feet (1,158 m), which makes it the third-longest suspension span in the United States and 27th longest suspension span worldwide. It is also one of the world's longest bridges overall .
This list ranks the world's cable-stayed bridges by the length of main span, i.e. the distance between the suspension towers. The length of the main span is the most common way to rank cable-stayed bridges. If one bridge has a longer span than another, it does not mean that the bridge is the longer from shore to shore, or from anchorage to ...
The John A. Roebling Suspension Bridge (formerly the Cincinnati-Covington Bridge) is a suspension bridge that spans the Ohio River between Cincinnati, Ohio, and Covington, Kentucky. When opened on December 1, 1866, it was the longest suspension bridge in the world at 1,057 feet (322 m) main span, [ 3 ] which was later overtaken by John A ...
