While the hectic summer construction season has come and gone, road closures never cease.
This time, the Alaskan Way Viaduct is undergoing its semiannual inspection and a few blocks away, Aurora Avenue North will close near Seattle Center, so workers can install a sewer line for the Mercer West project.
- All lanes of the Viaduct from South Spokane Street to the Battery Street Tunnel will close from 5 a.m Saturday to 6 p.m. Saturday, and from 6 a.m Sunday to 6 p.m. Sunday. Crews normally check for cracks in the 50-year-old concrete, check for any sinking in the columns, and sometimes replace the road stripes or signs. Part of the Viaduct sagged more than 5 inches following the 2001 Nisqually Earthquake, and was reinforced; and early next year, a deep-bore tunneling machine is scheduled to pass below the Viaduct at Yesler Way.
- Aurora Avenue North from the Battery Street Tunnel to Valley Street will close all weekend, from 11 p.m. Friday until 5 a.m. Monday. But east-west Mercer Street will remain open.
The state and city transportation departments say they coordinated the closures to disrupt traffic only one weekend, rather than several weekends.
