Resum
(ENG) The "Dos Valiras" Tunnel connects the valley of the river Valira del Nord (Northern Valira) with that of the river Valira de Orient (Eastern Valira). At its western extreme it reachs into the Valira del Nord which it crosses by means of two bridges. These bridges give on to a large roundabout which is in great part significantly raised due to its hilly terrain. This has been achieved by means of a structure of pre-stressed concrete divided into six stretches joined by hinges. It is a public work of the greatest import, the most important ever undertaken in Andorra-leaving aside the large tunnels constructed recently
