The Paso Internacional Los Libertadores, also called Cristo Redentor, is a mountain pass[citation needed] in the Andes between Argentina and Chile.

It is the main transport route out of the Chilean capital city Santiago into Mendoza Province in Argentina and so carries quite heavy traffic.

From the Argentine side the route to the pass is a slow, gentle incline until entering a tunnel at approximately 3,200 meters (10,500 feet) elevation.

Opened in 1980, the Tunnel of Christ the Redeemer (Spanish: Túnel Cristo Redentor) is 3,080 m (10,105 ft) long, and serves as an important land crossing between Chile and Argentina.

The pass was the highest point of the road before the opening of the tunnel lowered the maximum elevation by 600 m (1,969 ft), eliminated 65 switchbacks and shortened the route by 10 km (6 mi).
