Marão Tunnel, Road tunnel through Serra do Marão mountain range, Portugal
The twin-tube Marão Tunnel extends 5.6 kilometers beneath the Serra do Marão mountains, connecting Vila Real with Porto through the A4 motorway.
The construction of this major infrastructure project started in October 2014 and reached completion with its official inauguration on May 7, 2016.
The tunnel represents a transformative connection between the coastal and inland regions of northern Portugal, linking different economic and social territories.
Motorists using the tunnel save substantial time compared to the previous mountain route, with modern ventilation and lighting systems ensuring safe passage.
Engineers employed 22 specialized construction machines to excavate the parallel tunnels, creating Portugal's longest underground road passage.
