Devil's Slide Excavation Done for 2 Tunnels

January 26, 2011

Construction crews digging California's first highway tunnel in nearly 50 years have completed the excavation of the twin bores of the new Devil's Slide Tunnel on Highway 1.

About a year's worth of work remains before the tunnels and connecting bridges open to traffic, but the noisy, dusty, muddy job of digging two long holes through San Pedro Mountain is done, after a little more than three years.
