What would WSDOT do if Bertha stopped while beneath the viaduct?

WSDOT would first ensure that the viaduct was safe for daily use. The viaduct is being monitored 24/7 by a high-tech system that watches for any motion or settlement in the structure (this video provides an overview of that system). Once inspectors determined that the viaduct was safe, WSDOT would work to reopen the structure until the contractor, Seattle Tunnel Partners, was able to resume mining. WSDOT would continue to work with partner agencies to keep people moving while the viaduct was closed.
