Concessionaire Tunel d'Envalira Lmt has awarded the $50 million contract for the 3 km bi-directional tunnel, gallery, and ventilation shaft to a jv led by Necso that will also construct a viaduct and toll plaza. Elevation is 2,000 m in the Pyrenees and weather is a factor. Tunnel will be driven by drill/blast from both ends in 30 months and will provide an alternative all-weather route to France.
