Two advisories to start the morning:
ANOTHER HIGHWAY 99 CLOSURE: WSDOT also has another announced closure of Highway 99 between East Marginal and Atlantic for the Spokane St. Overcrossing project’s finishing touches just south of the West Seattle Bridge, 9 pm tonight-5 am Wednesday. (We’ll be verifying this with WSDOT before day’s end, as they have noted it’s weather-dependent and also that there’s a chance the work could be done sooner than expected. We’re also checking with WSDOT today to verify details of the announced closure of the Alaskan Way Viaduct for a followup inspection this coming Saturday, March 22nd.)
7:47 AM – DOWNTOWN EMERGENCY: A helicopter is reported to have crashed near the Space Needle/Seattle Center and that’s what the black smoke is downtown. We’re going to break this out separately. Avoid that area.
8:21 AM: Here’s our separate story – all regional news outlets are covering this too; it is reported to have been the KOMO TV helicopter – Channel 4 is right across Broad Street from the crash scene. KIRO and KING also have their headquarters a couple blocks away.
12:59 PM – HIGHWAY 99 UPDATES: *No* closure tonight, WSDOT now says. Tentatively scheduled for tomorrow night. Meantime, the time frame of Saturday’s Alaskan Way Viaduct closure is confirmed for 4:30 am-7 pm.
3:02 PM – SEATTLE CENTER UPDATES: 5th Avenue has reopened. Part of Broad, including the crash scene, has not. This SDOT tweet has the latest.
