The Eisenhower Tunnel: "Not Just Another Bore"

The Eisenhower Tunnel (I-70, Colorado) is a marvel of highway engineering and American braggadocio. Punching through nearly 2 miles of pure Rocky Mountain granite, this sleek tunnel saves motorists from a 9-mile, overland detour through Loveland Pass, but results in significant closures of I-70 when blizzard conditions are present on either end of the tunnel. (Would you want to exit a dry tunnel only to be blasted by a blizzard and a bevy of incliment weather-related accidents?) In addition, while the tunnel was being built, "approximately 1 million cubic yards of material was cleared from each bore. 190,000 cubic yards of concrete was used for each tunnel lining." I think that's damned interesting!
