The invention relates, for example, to the covering of a gutter (11) made at the junction between two traffic lanes (12). According to the invention, this covering is effected by covering elements (15) which are simply placed one after the other on two longitudinal girders (14), with, from one to the next, an open-worked butt linkage (22) allowing them to successively prop each other longitudinally, and with, at each of the ends of the assembly, a crosspiece (17) which, solidly attached to the longitudinal girders (14), props such an assembly both longitudinally and transversely and vertically. Application, in particular, to the making of a gutter in the axis of a bridge. <IMAGE>
