1:08 PM: WSDOT has announced the next Highway 99 tunnel closure for this Friday night and Saturday morning, and listing what’ll be done while it’s closed:
Both directions of the State Route 99 tunnel in Seattle will close from 10 p.m. Friday, Feb. 7, to 6 a.m. Saturday, Feb. 8, for maintenance.
Washington State Department of Transportation will start closing northbound and southbound lanes at 9 p.m., with the tunnel fully closed by 10 p.m. Drivers going south on SR 99 will need to take the Harrison Street off-ramp, and northbound SR 99 drivers will need to take the Alaskan Way off-ramp. Also, the Sixth Avenue and Royal Brougham Way on-ramps will close at 9 p.m.
The closure will let crews do several important tasks, including:
-Fire suppression testing.
-Cleaning and marking drains.
-Fixing lights.People traveling through downtown Seattle Friday night should use alternate routes
The topic of nonfunctioning lights on 99 by the tunnel came up in a recent comment discussion, so we’re checking with WSDOT on specifics.
3:41 PM: WSDOT hasn’t replied to our inquiry yet, but has just announced that this closure is postponed “to a later date.”
