The above diagrams shows a typical bridge cross section. The cross section indicates 6 precast beams supporting a deck slab. The bridge is using a cantilever abutment
The bridge plan view provide information of the bridge length and width. The above diagram also show a small piece of slab called 'transition slab' located on both sides of the bridge end . The river bank on the upstream and downstream of the bridge are protected. The protected lenght is around 10m but the actual lenth depend on the drainage calculation
The diagram shows a 31m bridge crossing a small river. The bridge is constructed using precast beams with reinforced concrete deck.
Basic parts of bridge can be easily identified via the above diagram. The main components are af follows: [1] bridge deck [2] beam [3] abutments [4] wingwall [5] piles
