Road infrastructure, Bridges, Tunnels, Construction Supervision and Project Management
Road link 5.990m long, developing between the Ribeira de São Jorge area and the localities of São Jorge and Arco de São Jorge, in the municipality of Santana (northern coast of Madeira Island). It integrates along its path:
- three tunnels with a total length of 4,398m (1,643m + 1,568m + 1,187m) including seven escape tunnels; - three viaducts with a total length of about 550m; - three roundabouts, at Ribeira de S. Jorge, at S. Jorge and at Arco de S. Jorge, which interconnects with the existing local road network.
The road has a typical cross section with a platform of 9m in the open-air section, 9.6m in the tunnel section and 11.9m in the bridges. The geometric characteristics of the layout satisfy the basic design speed of 70 km/h (except for roundabout approaches and maximum slope gradients).
