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

Early history

The simplest type of a bridge is stepping stones, so this may have been one of the earliest types of footbridge. Neolithic people also built a form of a boardwalk across marshes, of which the Sweet Track, and the Post Track are examples from England, that are around 6000 years old. Undoubtedly ancient peoples would also have used log bridges; that is a timber bridge that fall naturally or are intentionally felled or placed across streams. Some of the first man-made bridges with significant span were probably intentionally felled trees. Among the oldest timber bridges is the Holzbrücke Rapperswil-Hurden crossing upper Lake Zürich in Switzerland; the prehistoric timber piles discovered to the west of the Seedamm date back to 1523 B.C. The first wooden footbridge led across Lake Zürich, followed by several reconstructions at least until the late 2nd century AD, when the Roman Empire built a wooden bridge. Between 1358 and 1360, Rudolf IV, Duke of Austria, built a 'new' wooden bridge across the lake that has been used to 1878 – measuring approximately in length and wide. On April 6, 2001, the reconstructed wooden footbridge was opened, being the longest wooden bridge in Switzerland. A clapper bridge is an ancient form of bridge found on the moors of Devon ( Dartmoor and Exmoor) and in other upland areas of the United Kingdom including Snowdonia and Anglesey, Cumbria, Yorkshire and Lancashire. It is formed by large flat slabs of stone, often granite or schist, supported on stone piers (across rivers), or resting on the banks of streams. Although often credited with prehistoric origin, most were erected in medieval times, and some in later centuries. A famous example is found in the village of Postbridge. First recorded in the 14th century, the bridge is believed to have been originally built in the 13th century to enable

The special popularity of the bridge was gained through angular sculptures of four winged lions crowning the abutments. They were designed by sculptor Pavel Sokolov (1764-1835), who also contributed lions for Bridge of Lions.

Design

Design of footbridges normally follows the same principles as for other bridges. However, because they are normally significantly lighter than vehicular bridges, they are more vulnerable to vibration and therefore dynamics effects are often given more attention in design. International attention has been drawn to this issue in recent years by problems on the Pont de Solférino in Paris and the Millennium Bridge in London. To ensure footbridges are accessible to disabled and other mobility-impaired people, careful consideration is nowadays also given to provision of access lifts or ramps, as required by relevant legislation (e.g. Disability Discrimination Act 1995 in the UK).Schlaich, Mike, et al., ''Guidelines for the Design of Footbridges'', International Federation for Structural Concrete, 2005, Some old bridges in Venice are now equipped with a

Railways

It was originally usual for passengers to cross from one railway platform to another by stepping over the tracks, but from the mid-19th century onwards safety demanded the provision of a footbridge (or underpass) at busier places. However, in some quieter areas, crossing the line by walking over the tracks is possible.

Catwalk

Narrow footbridges or walkways to allow workers access to parts of a structure otherwise difficult to reach are referred as catwalks or cat walks.

In developing countries

Since the early 1980s, several charities have developed standardized footbridge designs that are

for use in developing countries. The first charity to develop such designs was Helvetas, located in Zurich, Switzerland.
Designs that can be sustainably and efficiently used in developing countries are typically made available to the public gratis.

The record for the longest footbridge in the world was claimed by then New York (state), New York State Governor David Paterson in an Oct. 3, 2009 Poughkeepsie Journal article about The Walkway Poughkeepsie Bridge across the Hudson River at Poughkeepsie, New York.

Disadvantages

Pedestrian overpasses over highways or railroads are expensive, especially when elevators or long ramps for wheelchair users are required. Without elevators or ramps, people with mobility handicaps will not be able to use the structure. People may prefer to walk across a busy road rather than climb a bridge, and this may be attributed to being in a hurry, perceiving the safety and security of the footbridge to be low, or simply because of feeling tiredness when climbing the stairs. It is recommended that overpasses should only be used where the number of users justify the costs. The operational concept of the footbridge is based on the notion that pedestrians need to walk a longer distance and exert more physical effort so that the traffic flow is not interrupted. This is not in line with the sustainability goals of the transport system promoting active travel such as walking and cycling. A change of policy to increase safety and walkability could involve transferring that effort of crossing the road to drivers who will need to wait longer so pedestrians can cross the road safely at street level. Narrow, enclosed structures can result in perceptions of low personal security among users. Wider structures and good lighting can help reduce this.
