UPDATE: WSDOT #Realign99 Closure Plan is Finalized!

It’s the longest highway closure in the history of the Puget Sound Region.

On January 11, 2019, the Washington State Department of Transportation (WSDOT) is permanently closing the Alaskan Way Viaduct, and the new SR 99 tunnel opens three weeks later in early February.

As WSDOT says,

“It’s a challenge we don’t take lightly, and so we’ve spent many months studying and refining our plans to ensure we take the most efficient, least impactful approach.”

They recently finalized their closure plans, and you can read about the final decisions that were made here.

One big change: both ramps near the stadiums are closing at 10 PM on January 4, one week before the Viaduct closes on January 11.

This will allow them to unbury on- and off-ramps to the new SR 99 tunnel. During construction of the tunnel, workers built, then buried, ramps on the tunnel’s south end. Crews then built a temporary road on top of the ramps to keep traffic moving during tunnel construction. Check out their video!

Other changes to their closure plan:

  • December 14: Crews will reduce the length of the northbound SR 99 transit lane in SODO by approximately 1,400 feet.
  • December 14: Crews will shorten the southbound right-turn lane to Harrison Street and narrow travel lanes on SR 99 near the SR 99 tunnel’s north portal.

By making these changes now, WSDOT is reducing the amount of work that would need to be completed during the Viaduct closure.
