The Braga Bridge is a continuous truss bridge. It was the fourth longest span of this type when it was completed in 1966. This list of continuous bridge spans ranks the world's continuous truss bridges in two listings: The first is ranked by the length of main span (the longest length of unsupported roadway) and the second by the total length of continuous truss spans.
In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports ( clear span ) or between the centers of the bearing surfaces ( effective span ): [ 1 ]
[5] [3] As a rule of thumb, the depth should be 1 ⁄ 24 of the span. [5] The width of the ribs is typically 130 mm (5 in) to 150 mm (6 in), and ribs usually have steel rod reinforcements. [5] The distance between ribs is typically 915 mm (3 ft). [3] The height of the ribs and beams should be 1 ⁄ 25 of the span between columns. [3]
Building codes determine the maximum deflection, usually as a fraction of the span e.g. 1/400 or 1/600. Either the strength limit state (allowable stress) or the serviceability limit state (deflection considerations among others) may govern the minimum dimensions of the member required.
The Russky Bridge over the Eastern Bosphorus in Vladivostok, Russia, with its 1,104 metres (3,622 ft) span, has the longest span of any cable-stayed bridge, displacing the former record holder, the Sutong Bridge over the Yangtze River in the People's Republic of China 1,088 metres (3,570 ft) on 12 April 2012.

Generally, the depth of the girder is no less than 1 ⁄ 15 the span, and for a given load bearing capacity, a depth of around 1 ⁄ 12 the span minimizes the weight of the girder. Stresses on the flanges near the centre of the span are greater than near the end of the span, so the top and bottom flange plates are frequently reinforced in the ...
