Wooden bridge - Mokkyo

Japanese: 木橋 - もっきょう

Also called "kibashi." A bridge whose girders are mainly made of wood. Wooden bridges have a long history, dating back to the primitive log bridges. In Japan in particular, most bridges before the Meiji period were wooden girder bridges, and even today they are used for simple bridges and temporary bridges in rural areas. However, they are no longer used for modern bridges because they are inferior to steel and concrete in terms of material uniformity, reliability, durability, and strength. However, in countries such as Switzerland, new wooden bridges are still sometimes built to blend in with the natural environment, and in North America, there are movements to preserve historic old wooden bridges as cultural assets.

Japanese:

〈きばし〉ともいう。橋桁の主体を木造とした橋。原始的な丸木橋以来，木橋の歴史は古い。とくに日本では，明治以前の橋のほとんどは主桁に木材を用いた木桁橋（もくげたきよう）であったし，現在でもいなかの簡易な橋，一時的な仮設橋などに用いられているが，材料の均一性，信頼性，耐久性，強度において鋼やコンクリートに劣るため，近代的な橋には使われなくなった。しかし，今でもスイスなどでは自然環境との調和を理由に新たに木橋が建設される場合があり，また北アメリカなどでは，由緒ある古い木橋を文化財的な意味で保存しようとする動きもある。
