Konnyaku Bridge
A is a low water crossing bridge in Japan, so named locally because of the way it seems to tremble underfoot like ''konnyaku'' ( konjac) jelly. Several are even officially named "konnyaku bridge", and this type of bridge can be found throughout Japan. During low tide a konnyaku bridge can be crossed, but during high tide the bridge girdle and pier are submerged by water, rendering it unusable. Moreover, many are unsafe because they are narrow, lack hand rails, or have fallen into disrepair. Hence many are slated for demolition and are being replaced by other kinds of bridge. Examples that have been demolished include the Moguri and Hamatakabō bridges.

Low Water Crossing
A low-water crossing (also known as an Irish bridge or Irish Crossing, causeway in Australia, low-level crossing or low-water bridge) is a low-elevation roadway traversing over a waterbody that stays dry above the water when the flow is low, but is designed to get submerged under high-flow conditions such as floods. This type of crossing is much cheaper to build than a high bridge that keeps the road surface consistently above the highest water level, and is usually deployed in semi-arid areas where high-volume rainfall is rare and the existing channel is shallow (which requires extra ramping on the banks to build a more elevated bridge and thus costs more), particularly in developing countries. Low-water crossings are essentially elevated floodways, functioning like causeways under normal conditions and serving as limited fords during high- discharge conditions. They are generally considered unsafe for traffic during floods due to the potentially fast and turbulent cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
