The Washington State Department of Transportation is issuing a two-week warning: The Alaskan Way Viaduct will close between South Spokane Street and the south end of the Battery Street tunnel beginning April 29. The closure will last about two weeks.

The closure is a safety measure while the tunnel boring machine Bertha drills under the viaduct. Are we sure this is safe? When is the viaduct too unsafe to use? What happens if a sinkhole opens up near the viaduct? No one is saying.

During the closure, WSDOT is encouraging people to carpool, bike, walk, take transit, or just not even bother and work from home. More about the closure plan and transportation alternatives here.
