A treadway bridge could be built of floating spans or fixed spans. [47] An M2 treadway bridge was designed to carry artillery, heavy duty trucks, and medium tanks up to 40 short tons (36 t). [ 39 ] This could be of any length, and was what was used over major river obstacles such as the Rhine and Moselle.
A Bailey bridge is a type of portable, pre-fabricated, truss bridge. It was developed in 1940–1941 by the British for military use during the Second World War and saw extensive use by British, Canadian and American military engineering units. A Bailey bridge has the advantages of requiring no special tools or heavy equipment to assemble.
The Puente Nuevo (Spanish pronunciation: [ˈpwente ˈnweβo], "New Bridge") is the newest and largest of three bridges that span the 120-metre-deep (390 ft) chasm that carries the Guadalevín River and divides the city of Ronda, in southern Spain.
Submerged floating tunnels can be anchored to the seafloor (left) or suspended from a pontoon (right) A submerged floating tunnel (SFT), also known as submerged floating tube bridge (SFTB), suspended tunnel, or Archimedes bridge, is a proposed design for a tunnel that floats in water, supported by its buoyancy (specifically, by employing the hydrostatic thrust, or Archimedes' principle).
Several engineers have designed bridges on various alignments and with differing structural configurations. A proposal by Professor T.Y. Lin for a crossing between Point Oliveros and Point Cires featured deep piers, a length of 14 kilometres (9 miles), 910-metre-tall (3,000 ft) towers, and a 5,000-metre (16,000-foot) span, more than twice the length of the current longest bridge span.

A toll bridge until 1946, its common name is the I-90 bridge or Lake Washington Floating Bridge. It was the first floating bridge longer than a mile, and at the time was the longest floating structure in the world. It is now the second longest floating bridge in the world. Hood Canal Bridge. Completed 1961. Spans 6,521 feet (1,988 m).
It's a question that I think leaves most of us scratching our heads -- what exactly is the distinction between being Latino, Hispanic or Spanish? There's a difference, of course, between ethnicity ...
