Jan. 11, 2019 marks the start of one of the most demanding traffic challenges Seattle has ever seen. That’s when the Alaskan Way Viaduct closes and crews start three weeks of intensive construction to move State Route 99 off the viaduct and into the new SR 99 tunnel.
To help drivers and commuters during the three weeks SR 99 will be closed through Seattle, the Washington State Department of Transportation produced a new video showing ways to get real-time traffic information and learn more about commute alternatives.
“Those three weeks plus the additional two weeks or more of additional ramp closures will test the patience of commuters and travelers like never before, “said David Sowers, deputy administrator of the Alaskan Way Viaduct Replacement Program. “It’s why we need everyone who can to change their commutes –especially anyone who drives alone.”
Travelers will start feeling the pinch at 10 p.m. Friday, Jan. 4, 2019, when the SR 99 on-and-off ramps near Seattle’s stadiums close.
One week later, at 10 p.m. Friday Jan. 11, the Alaskan Way Viaduct shuts down between South Spokane Street and the south end of the Battery Street Tunnel.
After the tunnel opens in early February, it will take up to two additional weeks to complete a new northbound off-ramp into downtown Seattle.
“We know there are those who can’t change their work hours or routines,” said Sowers. “So if you have some flexibility, pitch in for your neighbors and yourself and help us all avoid gridlock for the three weeks it will take to open the new tunnel.”
