What happens after the Alaskan Way Viaduct closes?
SEATTLE -- Q13 News is looking ahead to what will happen after the three-week closure period for the Alaskan Way Viaduct. WSDOT officials say after the closure, the new State Route 99 Tunnel will open to drivers for the first time. When work crews are done re-aligning the highway and opening new ramps, the new 99 Tunnel will open to thousands of commuters and bring some much-needed traffic relief.
