On the Move

The real moment of truth for Bertha.

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.
