This type, along with thelog bridge are likely the oldest bridge types. Unlike all other bridges this bridge has no spans. Water is allowed to course between the stones forming the steps. This type of bridge is often seen in gardens inChina andJapan . It is one of several principal types found in such gardens. Sometimes one will find these as informal crossings of small streams when hiking, as they are often built by hikers during the drier seasons and are subject to being swept away (or at least disarranged) during periods of high, fast water.When this type appears in gardens open to the public the step-stones are usually quarried from rough blocks and may be smoothed on their upper surface by a
stone mason or topped with a smoothconcrete treading surface.A type of Step-stone bridge located in Taishun Country, Zhejiang province, China is considered to be very important. Its name is "Ding bu" (in English is Step-stone bridge). One of these Dingbus is called "Shishui Dingbu". It is in Shiyang Zhen, Taishun Country, and it has a long history, and it became national protection unit of China in 2006.
