Bridges and viaducts
Through the implementation of infrastructural works inserted in various orographic nature territories and in different urban contexts, the Company has improved the skill to build bridges and viaducts of various types and sizes. Thanks to the know-how and experience acquired in complex works, Itinera is now able to complete a large part of this type of work with its own resources, directly supervising its planning and management in order to reduce construction times, in compliance with the high-quality standards required by national and international clients.
Among the most significant works of recent construction stand out the Meier Bridge, an arch bridge designed by the American architect Richard Meier and built in Alessandria, the Marchetti Viaduct with a single-arch steel structure, the Lambro Viaduct built as part of the new External Ring Road of Milan (TEEM) and the Stura Bridge built as part of the Asti-Cuneo motorway infrastructure.
