Trackway for land traffic vehicles, preferably for magnetic levitation tracks, with pre-assembled trackway beams arranged on substructures produced by in situ concrete construction or pre-assembled construction. The trackway beams include one or more hollow, reinforced longitudinal pre-stressed concrete beams and trackway panels, which extend transversely to the pavement and protrude on both sides beyond the pre-stressed concrete beams. The trackway panels are separate components from the concrete beams. The concrete beams are constructed as pre-stressed concrete supporting pipes produced by molding concrete by centrifugal action and have flat upper supporting shoulders for supporting the trackway panels.
