TRAFFIC ALERT UPDATE: NB Viaduct reopens

5:27 AM: Reminder – northbound Highway 99/Alaskan Way Viaduct is now closed from here to the Battery Street Tunnel for the Rock ‘n’ Roll Marathon/Half Marathon. The official alert notes that the event could last as long as 3 pm, but the marathon’s own road-closure grid page says the 99 closure could end by late morning, so we’ll keep an eye on advisories and webcams like the one above (you can also use the city’s Travelers Information Map to check live video of the course on the Viaduct at Western – use the “downtown” section of the video camera list on the lower right area of the map page).

10:17 AM: Highway 99/AWV is open again – as verified by the aforementioned cameras. Other marathon-related road closures might still be in effect – see the “grid page” link above for potentially affected areas.

I think of myself as up on these type of things but it came as a surprise to me that 99 NB was closed for the marathon. Are the runners ever actually on it?

In fact, yes, just this second I tweeted about that. As mentioned above, you can see live video via the city’s Travelers Information Map – at lower right, choose live video, then choose downtown, then choose AWV @ Western. Right now (8:05 am as I type) they’re streaming by – running southbound in the northbound lanes. A static camera view shows a line of cones at Seneca so I believe that’s where they’re headed.
