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.
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 fixed link or fixed crossing is a permanent, unbroken road or rail connection across water that uses some combination of bridges, tunnels, and causeways and does not involve intermittent connections such as drawbridges or ferries. [1] A bridge–tunnel combination is commonly used for major fixed links.
The floating portion is then retracted under the O'ahu side of the fixed bridge at a rate of 14 inches per second to create a 650 ft navigation channel. [13] [14] The entire process takes 25 minutes to complete. [13] Retraction of the movable span is accomplished by two hydraulic winches located on the control pier on the southeast side of the ...
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).
Floating bridge may refer to: Bridges that float on water. Pontoon bridge; Submerged floating tunnel; Vlotbrug, a design of retractable pontoon bridge used in the ...
A floating suspension bridge is a type of suspension bridge supported by towers built on floating pontoons which are tethered to the seabed. The design is intended to overcome the difficulties of building suspension towers in locations where the water is particularly deep.
The Span Junction Set gives the MGB Double Storey bridge a multi-span capability and allows bridges to be constructed over supports which are either fixed or floating. These may include any combination of existing supports, pontoons, existing or improvised piers and the MGB Portable Pier.
