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 New River Gorge Bridge is a steel arch bridge 3,030 feet (924 m) long over the New River Gorge near Fayetteville, West Virginia, in the Appalachian Mountains of the eastern United States. With an arch 1,700 feet (518 m) long, the New River Gorge Bridge was the world's longest single-span arch bridge for 26 years; [ 4 ] [ 5 ] it is now the ...
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 ]
The bridge is the largest single span masonry arch bridge in Ireland, [3] and is constructed from ashlar masonry with a span of 33 metres (110 feet) and a rise of 6.7 metres (22 feet). It is framed by iron balustraded parapets made by the Royal Phoenix ironworks of Parkgate Street in Dublin.
The bridge was built under budget for $199,861 (equivalent to $3.64 million in 2023 dollars [5]) and, at 360 feet (110 m), [1] was the longest concrete arch span in the California State Highway System. When it was completed, it was the highest single-span arch bridge in the world, [6]: 45 and it remains one of the tallest. [7]
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 SAS portion of the eastern span replacement of the San Francisco–Oakland Bay Bridge (2013) is a single-tower asymmetric bridge with a main span of 385 m (1,263 ft). It is currently the largest SAS bridge in the world. [3] The Pingsheng Bridge (2006) in China is a single-tower bridge with a main span of 350 m (1,148 ft).
