Join us for a tour to see SR 99 tunnel crews preparing for the arrival of Bertha, the world’s largest tunneling machine. In addition to learning about WSDOT’s efforts to replace the viaduct, visitors will be treated to views of this massive project from the lower level of the Alaskan Way Viaduct. Space is limited. Additional tours will be available throughout the spring.

Reservations are required. Please view the walking tour event handout (pdf 340 kb) for registration and other important information.
