We’ve already mentioned this weekend’s planned Highway 99 closure, mostly for work on the Atlantic Street Overpass – but there’s more to it than The Viaduct. Here’s a detailed reminder from WSDOT, including details of a partial closure north of the Battery Street Tunnel:

Crews working above, below and on the ground will close State Route 99 through Seattle this weekend.

In SODO, contractor crews working for the Washington State Department of Transportation will unveil the permanent concrete shape of the South Atlantic Street overpass above SR 99 by removing temporary steel and timber beams that supported construction.

North of downtown, contractor crews working for the Seattle Department of Transportation will install a sewer line under the road for the Mercer Corridor project and grind the pavement in the southbound lanes of the Battery Street Tunnel.

“Scheduling all this work at the same time avoids several weekends of closures and keeps our construction on track,” said Matt Preedy, deputy administrator for the Alaskan Way Viaduct Replacement Program. “Drivers can help by planning their trips before they’re stuck in traffic.”

Closure details

Friday, Nov. 8 – Monday, Nov. 11

*Northbound SR 99 will be closed between South Spokane Street and Valley Street from 10 p.m. Friday to 5 a.m. Monday.

*Southbound SR 99 will be closed from the north end of the Battery Street Tunnel to Spokane Street from 10 p.m. Friday to 5 a.m. Monday.

*Southbound SR 99 will be reduced to one lane between Highland Drive and the north end of the Battery Street Tunnel from 10 p.m. Friday to 5 a.m. Monday.

For Sounders FC fans heading to a potential Sunday night playoff match at CenturyLink Field and for all drivers, WSDOT recommends leaving early, carpooling or taking transit. Drivers can stay up to date with all closures and roadway conditions by checking the Seattle traffic page, the What’s Happening Now page, or WSDOT mobile app.

(The following) weekend, additional construction on the South Atlantic Street overpass will affect SR 99 through downtown Seattle. Crews will close the right lane of southbound SR 99 between South King and South Atlantic streets, as well as the southbound off-ramp to South Atlantic Street from 10 pm. Friday, Nov. 15 to 11 a.m. Sunday, Nov. 17.

And of course, since we report West Seattle (and WS-relevant) news 24/7, if there are traffic troubles because of the work, you’ll find out about them here too.
