Engineers develop origami-style mobile bridge

Engineers at Hiroshima University have revealed designs for an innovative mobile bridge that could be used in the wake of natural disasters.

The university’s institute of engineering has tested the bridge over a river and found that a vehicle could travel across it. The bridge was set up without foundations and incorporates a scissor mechanism, which has been designed for easy transportation and construction.

People walked on the completed mobile bridge over the Hongo river in Fukuyama City at its first construction test.

The results of the Mobile Bridge Version 4.0 viability tests were presented at a symposium of the Japan Society of Civil Engineers (JSCE) last month by Ichiro Ario, assistant professor at Hiroshima University’s institute of engineering, .

Ario said: “From this test of a new bridge concept, the next generation of bridge technology starts on a new stage in the field of bridge engineering. It is possible to use a real deployable and smart bridge with a scissor-type bridge system using this structural theory. I will further promote the development and evolution of Mobile Bridge 4.0 in the future. Making Mobile Bridge stronger, longer, lighter, more compact, and quicker to set up will promote the development of infrastructure construction technology in general.”
