May 9 #99closure wrap-up

Posted on May 9 2016 11:17 AM
Commuters were treated to a welcome sight when they hit the roads Monday morning: a fully reopened Alaskan Way Viaduct. SR 99 through downtown Seattle was open to traffic by Sunday evening following a 10-day closure to allow the SR 99 tunneling machine to pass beneath the viaduct.
We’d like to thank travelers again for the patience and flexibility throughout the closure. Many folks took the opportunity to explore new ways of getting around, and we hope commuters continue to consider using alternatives to driving alone going forward.
Tunneling progress
Seattle Tunnel Partners has installed 52 rings since mining resumed on April 29. Crews have excavated 342 feet of the approximately 385 feet of tunnel to be completed beneath the Alaskan Way Viaduct. STP has told us they will take a short break from tunneling after they reach the 385-foot mark so crews can rest.
