The present invention relates to a variably dimensionable bridge (10) comprising pre-engineered components provided in a kit. The pre-engineered components are constructed of fibre reinforced polymer (FRP) composite material and include at least one floor module (14) for providing a floor; at least two girders (12) for providing opposing substantial vertical sides; and at least two cross beams (16) to lend support to the girders (12). Also described, is a method for constructing a bridge (10) of variable dimensions comprising the use of pre-engineered components provided in a flat-pack kit.
