The Punta Olimpica Tunnel is a vehicular transportation tunnel through high mountains, connecting the Callejón de Huaylas and Conchucos valleys of the Cordillera Blanca mountain range in Peru. The tunnel is intended to ease traffic on Route AN-107, one of the crossroads in the Ancash region linking the cities of Carhuaz, San Luis, and Chacas a distance of 100 km.
With a length of 1,384 meters, the tunnel is the longest vehicular tunnel in Peru and the highest in the world, located at 4,735 meters above sea level. Its drilling began on May 15, 2012, and ended on February 24, 2013. It opened in August 2013 in conjunction with Route AN-107.
The new road shortened travel time for the roughly 80 km stretch from 9 hours down to about 2.5 hours. It’s open all year round with possible snow closures. Tucked away within the Huascarán National Park, in north-central Peru, the tunnel bypassed the infamous and dangerous Punta Olimpica Old Road. Due to the construction of the new tunnel, the old road is no longer maintained with plenty of fallen boulders sitting in the middle of the path and the road subsiding in places.
