ABSTRACT OF THE DISCLOSURE A guideway for use for example as an elevated roadway is constructed by forming guideway units comprising a massive elongated metal channel having one or a plurality, usually at least three, tubular metal tension void members running lengthwise down its interior and connected to its inside walls along its entire length. The void forming members are connected to the channel walls via longitudinal web members. Transverse shear connectors may also be provided above thw void-forming members. The ends of the channel are closed and after hoisting each unit into position on spaced supports which engage beneath its ends it is filled with settable material, usually concrete, which encloses the tubular members to form a composite structure. The side walls preferably are inclined inward between a bottom sheet and the top vertical protions of the side sheets to give an aesthetic appear- ance, provide streamlining and reduced unwanted dead weight.
