What is coworking? If you have permission to telework and want to feel part of a community or experience the motivation that comes from working with people, coworking can be a great solution.

Common Questions

What part of SR 99 will be replaced?

WSDOT will replace the double-deck bridge section of SR 99 that runs along Seattle's waterfront from S. Holgate Street up to the Battery Street Tunnel. This structure is called the Alaskan Way Viaduct.

Are there roadway restrictions on the viaduct?

In 2001, WSDOT imposed roadway restrictions that remain in effect today. Vehicles with a gross weight of more than 105,500 lbs. are prohibited. Each single axle is not to exceed 20,000 lbs., and tandem axles are not to exceed 34,000 lbs. Trucks and buses must travel in the right-hand lane only. Further restrictions could be imposed in the future.

Is most of the traffic using the viaduct today going to downtown or through downtown?

The current viaduct carries approximately 110,000 vehicles per day just south of the mid-town ramps. Of this amount, approximately 17,000 vehicles enter or exit downtown at Columbia and Seneca streets, and 33,000 exit or enter at Elliott and Western avenues toward Belltown, Uptown, and neighborhoods along the 15th Avenue and Elliott Avenue corridor. The remaining 60,000 vehicles continue north through the Battery Street Tunnel, either exiting in the South Lake Union/Queen Anne area or continuing north across the Ship Canal.
