Footbridges
A footbridge (also a pedestrian bridge, pedestrian overpass, or pedestrian overcrossing) is a bridge designed solely for pedestrians.''Oxford English Dictionary'' While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk, that enables pedestrians to cross wet, fragile, or marshy land. Bridges range from stepping stones–possibly the earliest man-made structure to "bridge" water–to elaborate steel structures. Another early bridge would have been simply a fallen tree. In some cases a footbridge can be both functional and artistic. For rural communities in the developing world, a footbridge may be a community's only access to medical clinics, schools, businesses and markets. Simple suspension bridge designs have been developed to be Sustainability, sustainable and easily constructed in such areas using only local materials and labor. An enclosed footbridge between t ...

Log Bridge
A log bridge is a timber bridge that uses logs that fall naturally or are intentionally felled or placed across streams. The first man-made bridges with significant span were probably intentionally felled trees. The use of emplaced logs is now sometimes used in temporary bridges used for logging roads, where a forest tract is to be harvested and the road then abandoned. Such log bridges have a severely limited lifetime due to soil contact and subsequent rot and wood-eating insect infestation. Longer lasting log bridges may be constructed by using treated logs and/or by providing well drained footings National Parks Conference 1915, p. 59. "If we can design the abutment so that no moisture can collect under the logs the life of the bridge is materially increased." of stone or concrete combined with regular maintenance to prevent soil infiltration. This care in construction can be seen in the French bridge illustrated below, which has well locked dry set stone abutments and ...

Boardwalk
A boardwalk (alternatively board walk, boarded path, or promenade) is an elevated footpath, walkway, or causeway typically built with wooden planks, which functions as a type of low water bridge or small viaduct that enables pedestrians to better cross wet, muddy or marshy lands. Such timber trackways have existed since at least Neolithic times. In many seaside resort locations, boardwalks along the beach provide access to shops, hotels, and tourist attractions. The Jersey Shore in the United States is especially noted for its abundance of boardwalks. Some wooden boardwalks have had sections replaced by concrete and even "a type of recycled plastic that looks like wood." History An early example is the Sweet Track that Neolithic people built in the Somerset levels, England, around 6000 years ago. This track consisted mainly of planks of oak laid end-to-end, supported by crossed pegs of ash, oak, and lime, driven into the underlying peat. The Wittmoor bog tra ...

Stepping Stones
Stepping stones or stepstones are sets of stones arranged to form an improvised causeway that allows a pedestrian to cross a natural watercourse such as a creek, a small river; or a water feature in a garden where water is allowed to flow between stone steps. Unlike bridges, stepstone crossings typically have no spans, although wood planks or stone slabs can be placed over between the stones (which serve as the piers) to improvise as low-water bridges. Although their historical origin is unknown, stepping stones, along with log bridges, are likely to have been among the earliest means of crossing inland bodies of water devised by humans. In traditional Japanese gardens, the term ''iso-watari'' refers to stepping stone pathways that lead across shallow parts of a pond, which work like a bridge-like slower crossing. Using ''iso-watari'' for crossing ponds, or shallow parts of streams, one can view the aquatic animals and plants around or in the pond, like carp, turtles, and w ...

Simple Suspension Bridge
A simple suspension bridge (also rope bridge, swing bridge (in New Zealand), suspended bridge, hanging bridge and catenary bridge) is a primitive type of bridge in which the deck of the bridge lies on two parallel load-bearing cables that are anchored at either end. They have no towers or piers. The cables follow a shallow downward catenary arc which moves in response to dynamic loads on the bridge deck. The arc of the deck and its large movement under load make such bridges unsuitable for vehicular traffic. Simple suspension bridges are restricted in their use to foot traffic. For safety, they are built with stout handrail cables, supported on short piers at each end, and running parallel to the load-bearing cables. Sometime these may be the primary load-bearing element, with the deck suspended below. Simple suspension bridges are considered the most efficient and sustainable design in rural regions, especially for river crossings that lie in non-floodplain topography such a ...

Clapper Bridge
A clapper bridge is an ancient form of bridge found on the moors of the English West Country (Bodmin Moor, Dartmoor and Exmoor) and in other upland areas of the United Kingdom including Snowdonia and Anglesey, Cumbria, Derbyshire, Yorkshire, Lancashire, and in northern Wester Ross and north-west Sutherland in Scotland. It is formed by large flat slabs of stone, often granite or schist. These can be supported on stone piers across rivers, or rest on the banks of streams. History Although often credited with prehistoric origin, most were erected in medieval times, and some in later centuries. They are often situated close to a ford where carts could cross. According to the Dartmoor National Park, the word 'clapper' derives ultimately from an Anglo-Saxon word, , meaning 'bridging the stepping stones'; the ''Oxford English Dictionary'' gives the intermediate Medieval Latin form , , "of Gaulish origin", with an initial meaning of "a pile of stones".French and Provençal ''clapier ...

Rudolf IV (1 November 1339 – 27 July 1365), also called Rudolf the Founder (), was a scion of the House of Habsburg who ruled as duke of Austria (self-proclaimed archduke), Styria and Carinthia from 1358, as well as count of Tyrol from 1363 and as the first duke of Carniola from 1364 until his death. After the Habsburgs received nothing from the decree of the Golden Bull in 1356, he gave order to draw up the " Privilegium Maius", a fake document to empower the Austrian rulers.
