Longest mobile bridge system

Being able to move troops and tanks across rivers is an essential capability in military tactics. And that’s where mobile bridges come into their own – trucks carrying concertina’d bridge sections that can unfurl to span bodies of water blocking that path of an advancing army. The largest of these, able to achieve a maximum span of 75 metres, is the Sarvatra mobile bridging system – developed for the Indian Army by the country’s Research and Development Establishment in Pune. The Sarvatra consists of five truck-mounted 15-metre bridge sections, which can be deployed in 100 minutes to give a 4-metre-wide deck with a carrying capacity of 70 tons.
