This list of the longest beam bridge spans ranks the world's beam 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 types of beam bridges that allow for the greatest spans are cantilever bridges, continuous truss bridges, steel and concrete box girder bridges. If one bridge has a longer span than another it does not necessarily mean that the bridge is longer from shore to shore or from abutment to abutment.
This list only includes bridges that carry automobiles or trains, it does not include footbridges or pipeline bridges. The span must be 300 metres (980ft) or over to be included in the list. Because there is no official classification, some bridges may be missing.
This section ranks the world's largest extradosed bridges, the span must be 250 metres (820ft) or over to be included in the list. Because there is no official classification, some bridges may be missing.
