Somport Rail Tunnel, International rail tunnel in Pyrenees Mountains, France and Spain.
The Somport Rail Tunnel extends 7,874 meters through the Pyrenees Mountains, connecting the Pyrénées-Atlantiques department of France with Spain's Huesca Province.
The tunnel's construction began in 1908 and reached completion in 1928, marking a significant advancement in trans-Pyrenean transportation infrastructure between France and Spain.
This tunnel holds the distinction of monument historique inscrit status in France, recognizing its role in developing cross-border connections between French and Spanish communities.
Regular safety exercises and maintenance operations require periodic closures of the tunnel, with alternative routes available through the Col du Somport mountain pass.
The tunnel functions as both a transportation corridor and an emergency rescue facility, featuring specialized equipment and protocols for binational emergency response operations.
