The Washington State Department of Transportation is trying to quell anxiety over Bertha’s impending trip under downtown Seattle and the Alaskan Way Viaduct.
In a new video published by WSDOT, the department explains that “every square inch” where Bertha is tunneling under — two miles long and half a mile wide, 15 feet below the surface — will be monitored using “state-of-the-art” methods. The transportation department has hired Soldata to do the job. Soldata has monitored a range of projects across the globe, including rail tunnels in Barcelona and London.
