Engineers at Queen's University in Belfast have developed what they say is the world's longest flat pack arch bridge.

The bridge will be transported to site in flat-pack form but when lifted, will transform under gravity into an arch.

It will span 16m (53ft) and will weigh almost 300 tonnes and will be put up in a day.

It is due to be erected over the Wallington River in Waterlooville, Hampshire in the coming months.
