Since the design used the aluminum alloy and steel as the main materials, the product cost should not be unaffordable for emergency uses. For the design, it is definitely attainable for the imagined user in a disaster situation.
Most of the news agencies have provided the similar information that constructed by the university and BBC. It is a great design that focused on the issue that most designer might ignore.

The development funding is not mentioned in the article or from the university sites. Therefore, personally will assume that the funding is raised by the university and relevant engineering associations.
Personally thinks that this design is quite innovative in the way of applying existing design structure and mechanic to form new designs for the greater use such as building temporary bridges.
The bridge is developed by a team led by Dr. Ichiro Ario from Hiroshima University (Institute of Engineering), Japan.
"A crucial point is how to expand a portable bridge. Usually a crane and a team of technicians is needed, but not in this case," Dr Paolo Beccarelli, Assistant Professor in Architectural Structures at the University of Nottingham explained to BBC News. This makes it a quick and simple solution when emergency bridges are needed. [2]
This design not yet implemented to any case in the report, but from the tests they did with the fields, the design is said to be successful in its aim and application.
The Origami Bridge is intended to solve the problem that occur when there are mass destructions with natural disasters such as floods or earthquakes that resulted in the destroy of the local bridge. Whereas the design is aimed to substitute the local bridges with temporary bridge, furthermore to improve the transportation within the area aftermath. The design also considers the time matters during a disaster environment.
The product is designed in the way that the portable bridge can be expand from a folded mode to a bridge length takes up to across a river. It expanded in a scissor-like (90° turned scissor lift) action, then slides out the decks with end-to-end to provide platforms for vehicles.
This design is “Made of aluminum alloy and steel, it’s lightweight and easy to transport, yet sturdy enough for cars to cross.” [1]
Since the article reported that this is the fourth edition of the design, most of the problems are solved during the refurbishment of product. So there are not many problems with the design as they tested with the publics. But they plan to make the bridge “stronger, longer, lighter, more compact and quicker to set up”.
