Question: How long is the Transcanyon Waterline linking the north and south rims of the Grand Canyon?

Answer: 12.5 miles, carrying water from Roaring Springs on the North Rim to the South Rim. Built in the 1960s, the pipeline provides potable water and fire protection for all South Rim facilities as well as some inner-canyon sites in the Cross Canyon Corridor, including over 800 historic buildings.
