The Government has invested 5.6 million euros in the reorganization of Customs between La Línea de la Concepción (Huelva) and Gibraltar. Different modules have been built to expedite the entry and exit of people and vehicles. At the border access control points, a series of canopies have been set up with the self-supporting curved roof system.

The INCO 155.3 Curved Self-supporting profile allows reaching spans of up to 23 meters without an intermediate structure, mainly due to its 155 mm edge and its 3-wave geometry. In this case, due to the particularly reduced deflection of the project, the 1.20 mm thick INCO 155.3 Curved Self-supporting profile has been used to guarantee load behavior for a span between supports of 10.80 m.
