The state Department of Transportation has closed the Alaskan Way Viaduct, pushing 90,000 or so cars onto surface streets and Interstate 5.
Traffic in Seattle -- already a taxing experience -- will be getting a lot worse with the scheduled closure.
Just after midnight Thursday, the viaduct closed for roughly two weeks while Seattle's notorious tunneling machine Bertha begins digging beneath the aged piece of infrastructure.
Drivers ought to take heed, not just for the Friday commute, but also for a busy weekend that is likely to keep streets and highways packed with cars.
"Whether you drive or take the bus or train, everyone should have a backup plan," said Dave Sowers, WSDOT Alaskan Way Viaduct deputy program administrator, in a Monday morning news release. "And make sure you have a plan for the weekend as well. Seattle has Mariners games, a Sounders game and Sunday's May Day activities all scheduled this weekend."
Travel times on I-5 and elsewhere around downtown Seattle are likely to be up to 50 percent longer than normal during the closure, according to an analysis by Kirkland-based traffic data company INRIX.

WSDOT has created a website with resources for drivers trying to navigate the closure, but officials have also advised drivers to try to work from home or change their hours if at all possible.
Here are some other resources to help you plan your way through the closure:
Short commutes nearest the closure may be twice as long as normal, while areas farther out will still see up to 20 percent upticks in travel time, the analysis found.
At a Monday morning news conference, Sowers said he expects traffic impacts "regionwide," but hopes that more planning and coordination during this closure will make things go at least a little more smoothly.
"We did learn a lot from the 2011 closure," Sowers said.
The 2011 closure was scheduled for nine days while crews took down part of southern end of the viaduct. During that closure, rush hour started earlier and lasted longer, often twice as long, and Sowers said drivers went back to their "old habits" after a few days, rather than sticking to alternative plans for getting around the area.
Closing the viaduct during tunneling beneath is a precaution, with the biggest concern as Bertha sets out tunneling just 15 feet below the lowest foundations of the viaduct (which are already 65 feet underground), Sowers said. But the closure will also allow workers from WSDOT and contractor Seattle Tunnel Partners to get on top of the viaduct to monitor it more closely, he said.
There is no scenario where the state would suspend tunneling while Bertha is under the viaduct, Sowers said.

I know it is hella regional but we could very well see a disaster in a major city. Literally anything can happen with this.
