The invention relates to a guided transport permanent way overpass span having a U‑shaped cross section of which the two branches form lateral walls (4, 5) of said permanent way and of which the central zone connecting the two branches forms a slab (6) supporting said permanent way, said supporting slab (6) comprising at least one indentation (10, 11) formed in said slab longitudinally along said span and configured to be able to receive a support (12, 13) on which a guided transport vehicle intended to run along said permanent way can run, said span comprising, for each indentation, a longitudinal rib which extends under said supporting slab on the opposite side from this indentation (10, 11) and forming means of longitudinally stiffening said supporting slab. |
