Abstract (en)
A covering structure (100) for a roadway (250) at the entrance/ exit of a tunnel (200) comprising a supporting frame (50) surmounting at least in part the roadway (250) and extending in a direction longitudinal to the road for at least a length (52) leading to the entrance and/ or a length (54) following the exit of the tunnel (200). The structure further comprises a plurality of covering panels (70) arranged on the supporting frame (50). In particular, the covering panels are arranged along the longitudinal direction in order to create an alternate sequence of shielding areas (72) against the solar light combined with areas (74) where the solar light passes, to obtain a progressive and gradual lightning change on the roadway along the length (52) leading to the entrance of the tunnel and/ or along the length (54) following the exit of the tunnel and to maximize the safety for the passing vehicle drivers.
