Footway in a prefabricated design for roadside inclines or the like along motor roads where it may be a problem to build footways without involving large expenses. The structure comprises in combination: anchoring beams (6) being at their ends adapted to be fixed to first foundations (19) and to lie with their longitudinal direction along the roadside incline (2), possibly along the edge of a roadway (1), and to be interconnected to larger lengths, preferably in engagement with the ground along the whole length, transverse supporting beams (5) one end of which is adapted to be fixed to the ends of the anchoring beams (6) and carrying a cover in the form of gratings (8) or the like, as well as a railing (9) at the other end, and adjustable supporting legs (7) adapted to be mounted between second foundations (12) in the incline (2) and the outer portion of the supporting beams (5), said supporting legs (7) being preferably length-adjustable in a telescopic manner and being at both ends angularly adjustable in two planes, said railing (9) being in the form of a truss structure having sufficient mechanical strength to contribute substantially in supporting one or more intermediate auxiliary supporting beams without supporting legs between two supporting beams (5) having supporting legs (7). The footway may also be built without any relationship to existing road arrangements, and for example for broadening bridges where there is no separate footway originally. |
