CLOSURE ALERT: New date for next Highway 99 tunnel closure

WSDOT has announced the new date for the next Highway 99 tunnel closure, 2 weeks after it was announced and then canceled. The new date is this Friday night and Saturday morning, February 21-22:

Both directions of the State Route 99 tunnel in Seattle will close from 10 p.m. Friday, Feb. 21, to 6 a.m. Saturday, Feb. 22, 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.

If only that “maintenance” also included graffiti removal!

For the love of GOD…you have the tunnel closed, clean the graffiti. It couldn’t be easier with no cars. WHY do they keep closing the tunnel for weekend or night work and leaving the graffiti. I swear WSDOT hates the citizens of this state and just does stuff on purpose to annoy everyone for fun.

Well that’s the new National Theme from trump and the MAGAts (woo, sounds like a new band name) isn’t it? We must be faketriotic, just like them!

Really? You think the people who work for the government hate the state? Sad

Sorry, comment time is over.
