Scaffolding and centring used to build the arches were reused in the construction of the Dane Viaduct 15 miles (24 km) to the south. [1] The viaduct comprises 22 semi-circular arches with spans of 19.2 metres (63 ft) flanked by a pair of abutment arches of 5.5-metre (18 ft) span. The arch rings are 900 millimetres (35 in) thick.
An arcade is a succession of contiguous arches, with each arch supported by a colonnade of columns or piers. Exterior arcades are designed to provide a sheltered walkway for pedestrians; they include many loggias, but here arches are not an essential element. An arcade may feature arches on both sides of the walkway.
The Interim Walkway, from 11th Avenue and 30th Street to 34th Street divides the viaduct into two sides: a gravel walkway and an undeveloped section with rail tracks. The temporary walkway closed for renovation when the Tenth Avenue Spur was completed. [26] The High Line turns north to a point just east of Twelfth Avenue.
Urban footpaths may be constructed of masonry, brick, concrete, asphalt, cut stone or wood boardwalk. Crushed rock, decomposed granite, fine wood chips are also used. The construction materials can vary over the length of the footpath and may start with a well constructed hard surface in an urban area, and end with an inexpensive soft or loose ...
A skyway, skybridge, skywalk, or sky walkway is an elevated type of pedway connecting two or more buildings in an urban area, or connecting elevated points within mountainous recreational zones. Urban skyways very often take the form of enclosed or covered footbridges that protect pedestrians from the weather.
The masonry arch bridges of stone or brick are the most genuine of arch bridges, some lasting a thousand years. Because they are made of worked stone, there is a slight chance they might even stand without mortar, like the Pont du Gard aqueduct. Yet arch bridges using rough hewn stones like Changhong Bridge need mortar to stand.
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.
Walkway" is a more comprehensive term that includes stairs, ramps, passageways, and related structures that facilitate the use of a path as well as the sidewalk. [9] In the UK, the term "footpath" is mostly used for paths that do not abut a roadway. [10]
