Road closures near the SR 99 tunnel's future north portal

Posted on Nov 6 2012 10:34 AM

We're preparing to dig a pit in the work zone near Sixth Avenue North and Harrison Street, where our tunnel boring machine will end its journey in 2014. The following streets will remain closed until after the SR 99 tunnel opens to traffic:

  • - Sixth Avenue North between Thomas and Republican streets.
  • - Harrison Street between Aurora Avenue North and Broad Street.
  • - Republican Street between Aurora Avenue and Sixth Avenue North.
  •  
Our traffic page links you to a full list of construction closures, traffic cameras and more.
