(March 2010 view of the “low bridge,” from its tower, by then-Councilmember Tom Rasmussen)
With the Alaskan Way Viaduct‘s permanent shutdown and tunnel transition now three weeks away – 10 pm Friday, January 11th – recaps and reminders are rampant. New information continues to emerge, too. In her weekly update, City Councilmember Lisa Herbold includes this:
(T)he U.S. Coast Guard, which regulates bridge openings, has approved a temporary restriction from January 11 to February 9 to limit Spokane Street Bridge openings (i.e. the “lower bridge” adjacent to the West Seattle Bridge). The restrictions will be in place from 7-10 a.m. and 2 to 5 p.m., and prohibit openings for vessels of 5000 or more gross tons (see page 3 of the Coast Guard’s Notice to Mariners).
Though the “low bridge” is a city-owned structure, the Coast Guard has jurisdiction over the waterway’s use for maritime traffic, and it’s generally rejected calls over the past decade-plus for longer-term restrictions on the times when it “closes” to vehicle traffic. The Coast Guard did agree to pm restrictions during the 2011 closure related to demolition of the AWV’s southern section.
