SR 99 Lane Closures Enters Phase Two of Project

February 8, 2016 6:57am

An update on the SR 99/Aurora Ave lane closures: the north bound lanes reopened on Friday, a week earlier than expected. The second phase of the project begins today and is anticipated to have smaller traffic impacts.

According to WSDOT “phase two of the work to build foundations for the signs that will direct drivers to the future SR 99 tunnel will start at 8 p.m. Monday, Feb. 8. This second phase will require a one-block closure of the southbound right lane near Comstock Street while crews construct the final sign foundation near Comstock Street. Buses will merge into the general purpose lane at this location. This should last two to three weeks.”

WSDOT also warns that since buses will merge into the general-purpose lanes for one block during the next phase of work, there may be some backups.

And in case you were wondering (like we were) what exactly the first phase accomplished:

Crews working for the Washington State Department of Transportation:

  • Cut and removed some 1,600 square feet of pavement
  • Drilled four large underground shafts for the sign foundations
  • Installed rebar and poured concrete into the shafts
  • Cast new concrete median barriers
  • Installed underground power and communications lines to support electronic messaging systems for the signs
