Here's what to expect for getting around the Puget Sound area in 2019

SEATTLE — There will be big changes to how we get around in the Puget Sound area in 2019, beginning with the three-week closure of State Route 99 in Seattle.

The closure begins Jan. 11 as the roadway is realigned from the Alaskan Way Viaduct to the new tunnel beneath Downtown Seattle that replaces it.

On Super Bowl weekend, the state will throw a party--letting people walk, run and bike through the new tunnel--and say good-bye to the viaduct.

The viaduct will be torn down starting in February, after the tunnel opens.

Demolition will close two or three streets at a time, with the work done by June.

But many other projects, like work on an expanded convention center and the rebuild of the arena at Seattle Center for the NHL, will snarl traffic for years.

"This is the first stage in a five-year period that we're calling the period of maximum constraint," Heather Marx of the Seattle Department of Transportation told reporters last fall. "This is going to be a series of events that take place between now and 2023 that are going to completely shift the way we get around."

Near the end of March, buses will leave the downtown transit tunnel to make way for more light rail, adding to congestion on downtown streets.

This summer, tolls will start on the new SR99 tunnel, pushing car drivers onto surface streets to avoid the charge.
