Santa Ana Firm Wins Engineering Excellence Award

Sacramento, CA – HNTB Corporation of Santa Ana has received an Honor Award from the American Council of Engineering Companies of California (ACECCA) for their work on the Tom Lantos Tunnels in Pacifica and Half Moon, CA.


HNTB was contracted by Caltrans as the prime design consultant to find a solution to the dangerous coastal stretch of California’s State Highway 1. After years of studies, Caltrans decided to bypass the Devil’s Slide with two inland tunnels, providing a safe, dependable highway between the two towns. The twin tunnels rest in one of the most complex geological settings in California. The tunnels establish a safe, permanent connection between Pacifica and Half Moon Bay and advance the tunneling industry in California. The project helps to set the world standard in tunnel seismic safety. Because they lie along the active San Andreas Fault and four inactive fault lines, the twin tunnels had to withstand a 7.5 to 8.0 magnitude earthquake. Some European agencies were so impressed with Caltrans’ seismic criteria they adopted it for future tunnels.


HNTB Corporation will be honored at the 2014 EEA Banquet held on February 3 in Sacramento.  Registration:  ACECCA 2014 EEA Banquet Event
