The DRDO Sarvatra (lit. ' Everywhere ') [1] also known as Sarvatra Multi-span Mobile Bridge System is a truck-mounted, multi-span, mobile bridging system developed by Armament and Combat Engineering Systems (ACE) and Research and Development Establishment (R&DE) Engineers of Defence Research and Development Organisation (DRDO) [2] for the Indian army.
The plates provide a surface with a low coefficient of friction which can be attached to a supporting structure. This combination provides support while simultaneously allowing an object to move (slide) freely along the supporting surface. [1] The plate may be of polytetrafluoroethylene (PTFE),TEF-MET, [2] Lubrite [3] or steel according to the ...
Plate girder bridges are suitable for short to medium spans and may support railroads, highways, or other traffic. Plate girders are usually prefabricated and the length limit is frequently set by the mode of transportation used to move the girder from the bridge shop to the bridge site.

[2] Dock plates and dock boards are simply metal ramps which bridge the gaps between dock and truck. [4] Dock plates are generally made out of aluminium whilst dock boards are generally made out of steel for greater strength
Thousands of orthotropic deck bridges are in existence throughout the world. Despite the savings and advantages (up to 25% of total bridge mass can be saved by reducing deck weight, as the weight reductions extend to cables, towers, piers, anchorages, and so forth), the US has only about 60 such bridge decks in use as of late 2005.

It uses the same modular components as the Close Support Bridges. A standard bridge set is carried, launched and recovered from 3 specialist vehicles (1 x Automotive Bridge Launching Equipment (ABLE) and 2 x Bridging Vehicles (BV). Up to 44m of bridge can be built using this system, although only 32m is possible with the 3 vehicle combination.
