Quick note looking ahead to next weekend, as this one concludes: The southbound Alaskan Way Viaduct is scheduled to be closed overnight next Saturday night, from 11:59 pm December 6th until about 5 am December 7th, according to the newest “construction lookahead.” The reason for the closure between the Battery Street Tunnel and the West Seattle Bridge is described as “… crews remov(ing) a crane from the adjacent job site.”
