emblematic tunnel
History
The Añisclo tunnels are 4 tunnels located in the eastern half of the Huesca provincial highway (Spain) HU-631 that connects the towns of Sarvise (N-260b) - Fanlo - Nerín and Laspuña (A-138), one of the main functions of this road is to serve as access to the southern area of the Ordesa y Monteperdido National Park, specifically to the emblematic Anisclo canyon.
The possibility of prohibiting vehicle access on this road is currently being debated, since part of it is located within the Ordesa y Monte Perdido National Park and the area has a high ecological value, in fact one of the places where it is easiest to spot wildlife is on the road section.
Characteristics
The lengths of the 4 tunnels are:.
• - Year 1: 86 m.
• - Year 2: 62 m.
• - Year 3: 33 m.
• - Year 4: 40 m.
The 4 tunnels are monotubes, narrow and excavated in living rock, which is why ice stalactites frequently form inside them in winter.
