Caltrans Mystery Tour Of Caldecott Tunnel
"s, the Caldecott is cool, thanks to all its secret passageways, shadowy enough to make Nancy Drew drool. And its giant fans with 8-foot-wide blades. And its cavernous barely lit mineshaft-like wind tunnels, running above the full 3/4-mile lengths of the three bores -- complete with stalactites squeezing out of the mountain and a couple of mini four-wheelers so workers can zip back and forth above commuter heads."
