While we were downtown, this update came in from SDOT:
The far left lane (westernmost lane) remains closed on the Alaskan Way Viaduct northbound between Main and Cherry streets due to an overnight accident. SDOT crews are installing a temporary flex-rail. The work should be completed by noon or 1:00 p.m. and the left lane will be re-opened at that time. At this time three lanes are open for traffic past the work zone.
P.S. You can now get Viaduct-related news as part of the mix on our new MORE page — we just added it to the parameters by which the automated feeds there are sorted.
