ABSTRACT OF THE DISCLOSURE The disclosure relates to a portable bridge in the form of a permanently assembled unitary structure. The structure has a base frame which includes at least two main longitudinal supporting members extending from end to end of the structure in spaced parallel positions. These members have opposite end portions adapted to rest on supporting surfaces at opposite sides of an area spanned by the bridge in use. The frame also includes two trans- verse members which extend between adjacent end portions of the respective longitudinal members at opposite ends of the bridge structure. The transverse members are ac- cessible from externally of the bridge structure and are adapted to provide attachment points for facilitating transportation and/or securing of the structure in a position of use. The structure also includes a deck pro- viding a roadway surface which extends longitudinally of the bridge structure from end to end thereof and which includes a plurality of main deck members capable of supporting loads to be carried on the bridge. The main deck members extend transversely of the main longi- tudinal members of the base frame and are supported on and coupled to the longitudinal members.
