A footbridge is a Bridge designed for Pedestrians and in some cases Cyclists and Horse Riders , rather than Vehicular Traffic . An enclosed footbridge between two buildings is sometimes known as a Skyway . Footbridges are often situated to allow pedestrians to cross water or Railways in areas where there are no nearby roads to necessitate a Road bridge, They are also located across roads to let pedestrians cross safely without slowing down the traffic. The latter is a type of Pedestrian Separation Structure , examples of which are particularly found near schools, to help prevent children running in front of moving cars. Small footbridges can also be used for decorative effect in ornamental gardens. Types of footbridge (which are not also types of road bridge) include: Footbridges can also be built in the same ways as road or rail bridges; particularly include The Iron Bridge at Ironbridge , Shropshire , the Old Bridge at Pontypridd and Windsor Bridge at Windsor, Berkshire . Most footbridges are equipped with Parapet s to reduce the risk of pedestrians falling. Where they pass over busy roads or railways, they may also include a fence or other such barrier to prevent pedestrians from jumping, or throwing projectiles onto the traffic below. EXAMPLES footbridge in St Petersburg , Russia .]] Examples include:
RAILWAYS with two side platforms, and a footbridge connecting them.]] It was originally usual for passengers to cross from one Railway Platform to another by stepping over the tracks, but from the mid-nineteenth century onwards safety has demanded the provision of a footbridge (or Underpass ) at busier places. DESIGN Design of footbridges normally follows the same principles as for other bridges. However, because they are normally significantly lighter than a vehicular bridge, they are more vulnerable to Vibration and Dynamics are often give more attention in design. International attention has been drawn to this issue in recent year 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 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, ISBN 2-88394-072-X SEE ALSO REFERENCES |
