San Rafael tunnel
The San Rafael Tunnel ( Túnel San Rafael ) is a road tunnel in the La Paz department in the South American Andean state of Bolivia.
The tunnel is on the Ruta 3 trunk road , which leads from La Paz over the La Cumbre Pass into the Bolivian Yungas , via Coroico and San Ignacio de Moxos to Trinidad , the capital of the Beni department . The tunnel has a length of 1,374 meters and lies at a height of 2845 m to 2942 m . It was built between 2001 and 2004 as part of the re-routing of Ruta 3, which, as the Yungas Strait, was long considered one of the most dangerous high-altitude roads in the world. Between Cotapata and Coroico, the construction of the San Rafael tunnel made it possible for Ruta 3 to have a completely new route in this section between 2001 and 2006 and for the first eighty kilometers to Coroico to be completely asphalted.
