Bridges are a common feature of the built environment and one of the key elements of civil engineering. The basic principles of bridge design are dependent on the nature of the spanning structure; its shape, materials, means of support, distance spanned, terrain, function, budget, exposure and so on.
The three basic types of bridge structure are:
Other definitions related to bridges include:
- A green bridge - a crossing that allows the safe passage of wildlife.
- An overbridge - a bridge crossing over a transport corridor.
- An underbridge - a bridge crossing under a transport corridor such as a railway.
- A viaduct - a bridge like structure composed of a series of spans, used to carry roads and railways across valleys and other depressions.
- A half through bridge - a bridge in which the lower chord carries the vehicular or pedestrian traffic.
- A through bridge - a bridge in which the lower chord carries the vehicular or pedestrian traffic and having cross-bracing located above the traffic.’ Ref Iron and Steel bridges: condition appraisal and remedial treatment, published by CIRIA in 2008.
- The span of a bridge is the horizontal distance between its supports.
- The underside of a bridge is described as a 'soffit'.
