SEATTLE -- The southbound lanes of the Alaskan Way Viaduct will close through downtown Seattle this weekend, as work continues to prepare for the opening of a new tunnel.

New pavement is being laid, utilities are being moved, and overhead signs are being hung, all in preparation for a major shutdown.

“Sometime before we open the (Hwy 99) tunnel, we have to close the Viaduct for three weeks,” says Laura Newborn, spokesperson for the Washington Department of Transportation.

Newborn confirms that this weekend’s works is in preparation for the 3-week closure, but still isn’t sure of the timing of the longer, much more impactful closure.

“Most of us, including everyone here too, wish we had a date, but we don’t yet,” Newborn tells KOMO News. “We’re just not close enough on the work inside the tunnel to really know a firm date.”

But since southbound 99 on the Viaduct is mostly protected from the rain, work will go on as planned, meaning all southbound lanes of Highway 99 will be closed between the Battery Street Tunnel and Spokane Street.

On the bright side...This is the only major closure you'll have to contend with this weekend: A planned lane reduction on Northbound I-5 in Seattle has been postponed due to weather.
