The Machico-Caniçal Expressway, 8 km in length, is part of the Madeira Island's new development program, which connects Funchal city to Caniçal village via a continuous expressway along the island's southern coast. This expressway crosses an extremely mountainous region affected by the existence of two very heterogeneous geological volcanic complexes, generally covered by unstable slope deposits or by thick alluvial deposits, leading to the construction of a wide range of civil engineering Works. This paper presents the main aspects related with the design and construction of six double tunnels along the referred expressway, as well as a number of safety aspects related to these tunnels.
