摘要： The bridge includes a plurality of foldable portions or modules (M) interconnectible releasably in sequence longitudinally. Each module (M) includes a central deck member (9) and two lateral deck members (10, 11) articulated to opposite sides of the central deck member (9). Respective longitudinal beams (13-16) extend from the lower faces of the lateral deck members (10, 11) and, together with the homologous beams of the other modules (M), constitute the load-bearing trusses of the bridge in its condition of use.Conveniently, the bridge is constructed by a method of assembly which provides for the use of a load-bearing assembly structure or forestarling (S). This load-bearing assembly structure (S) is assembled in a position of assembly on a first side (B.sub.1) of the gap (R) to be spanned by the bridge and is then advanced until it reaches the other side (B.sub.2) of the gap. During a subsequent stage in the assembly of the bridge, the load-bearing assembly structure (S) supports a plurality of interconnected modules (M) and guides them for sliding until they reach the opposite side (B.sub.2).Upon completion of the assembly, the load bearing assembly structure or forestarling (S) is connected firmly to the structure formed by the modules (M) so as to contribute to the structural strength of the bridge.
