DESCRIPTION

The freeway link between Machico and Caniçal has a total length of 7,1Km, with open sky and tunnel sections, having a typical cross section platform of 2×2 lanes with 18,5m large when in contiguous and leveled carriage ways and with 22,9m of total width when in separated and super elevated carriage ways. This project comprises five double tunnels with sections separated by a central septum of 16m, having each tube 9m of useful width, and which integrate a platform with two unidirectional lanes, shoulders and sidewalks. The Caniçal’s Double Tunnel crosses the mountainous region that separates Machico from Caniçal, having a total length of 2.100m and comprising pedestrian emergency evacuation galleries (each 200m) and the most recent technology concerning signaling and safety, namely detection and fire fighting, lighting and ventilation systems. This project also integrates three separate grade intersections at the local crossroads, nine reestablishments (in a total extension of 2.200m), three special engineering structures (one viaduct and two bridges) and several conventional engineering structures. Engineering specialties involved: Road alignment and earthworks, transversal and longitudinal drainage, paving, fencing and landscape design, geologic and geotechnical investigations (20 retaining walls), fire fighting network, lighting infrastructures, telecommunication and electric power supply, signaling and safety equipment.
