Bridges refer to buildings built for roads to cross natural or man-made obstacles. Generally speaking, a bridge consists of five main parts and five secondary parts. The five components refer to the superstructure and substructure of the bridge span which bear the transportation load of automobiles or other vehicles, and are the guarantee of the safety of the bridge structure.

(1) bridge span structure (or bridge hole structure. Superstructure),

(2) the bridge bearing system,

(3) Pier and abutment

(4) Pile cap

(5) Digging a well or pile foundation.

The five small parts refer to the parts directly related to the service function of the bridge, formerly known as bridge deck structure, including (1) bridge deck pavement, (2) waterproof and drainage system, (3) railing, (4) expansion joint and (5) lighting. The ancillary structures of large bridges also include bridge heads and approach bridges.
