Kawasaki bridge shows how Japanese wood construction methods are a classic, even till today

Traditional Japanese wood construction still works – components are quick and easy to fit together while not compromising the structural integrity of the structure. This bridge in Kawasaki is one example.

Some time ago last year, architects Vuild installed a temporary bridge in a public space in Kawasaki prefecture, Japan.

Spanning 16 metres long and 2.7 metres high, the cross-laminated structure was put together using a combination of a CNC milling machine and a Japanese traditional wood construction method. Each joint is secured using wooden driving plugs, which can be easily separated by pulling it out. The compressive strength of the joint parts can be mitigated by adopting an arch to the whole form. The wooden driving plugs also resist the shearing force.

In the end, the entire bridge comprises eight modules, two bases and one keystone. Assembling and dismantling the bridge only took eight people and one hour.
