The Severn Bridge. The Severn Bridge is located close to the former Aust Ferry. The bridge is a suspension bridge of conventional design, with the deck supported by two main cables slung between two steel towers. In 1966 the cables supporting the bridge deck were spun from 18,000 miles (29,000 km) of wire. [13]

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.
Map showing the Second Severn Crossing in relation to other crossings and the estuary itself. The Prince of Wales Bridge (Welsh: Pont Tywysog Cymru), previously the Second Severn Crossing (Welsh: Ail Groesfan Hafren) until July 2018, is the M4 motorway bridge over the River Severn between England and Wales, opened in 1996 to supplement the traffic capacity of the Severn Bridge built in 1966.
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 first road bridge across the Severn River was a drawbridge built in the late 1920s. [From Anne Arundel County site: In 1886, the long-awaited Severn River road bridge was built on the site of the present Rte 2 bridge. All of these were made of timber and have since been replaced with masonry bridges in slightly different positions.]
