Caltrans Finishes Excavation of Devil�s Slide Tunnels
Caltrans last week finished excavating the new Devil�s Slide Tunnel in coastal San Mateo County. Construction crews from general contractor Kiewit removed the last of the soil from the northbound tunnel, while the last of the excavation for the southbound tunnel was completed a week earlier.
�Tunneling is never easy,� says Bijan Sartipi, Caltrans District 4 director. �It requires intelligent planning, brilliant engineering and a lot of old-fashioned hard work. Reaching this milestone required plenty of all three.�
