Seattle reviews emergency traffic plan in case viaduct has to close

SEATTLE — The Alaskan Way Viaduct has sunk more than an inch since crews pumped out groundwater to build a repair pit for the tunnel machine, Bertha.

But what if it keeps sinking and becomes damaged to a point it has to close?

There's less room for vehicles now on Second, because of a new bike lane, but SDOT doesn't see that as a problem.

"If you're someone who can take advantage of biking rather than driving, that's something we would recommend if the viaduct were not available for use," Sheridan said.
