From SDOT‘s weekly “lookahead,” just out:
SOUTH PARK BRIDGE OVERNIGHT SURFACE-TRAFFIC CLOSURES: Thanks to the tipster who let us know this morning that a mobile sign had gone up on the South Park Bridge with news of upcoming overnight closures. That put us on the lookout for the details that are in the “lookahead” – Monday through Friday nights (technically Tuesday-Saturday mornings, March 17-21) next week, the bridge will be closed to surface traffic 12:01 am-5 am. The closures are scheduled to repeat a week later, same times, March 24-28. (added) As explained by the county: “The closure will be confined to the overnight hours and will allow the contractor to complete bridge painting and finishing work in areas accessible only when the bridge is partially open. While work is underway, the waterway will remain open to recreational vessels that don’t require full openings to clear the bridge. Because the work will be performed overnight, traffic impacts should be minimal.”
ALASKAN WAY VIADUCT INSPECTION CLOSURE: When first word of the March 28-29 closure emerged last Monday, WSDOT wasn’t able to tell us whether it would be a full weekend closure or “all day Saturday plus all day Sunday.” Looks like it’s the latter; the “lookahead” lists the closure as 6 am-6 pm each day, Saturday 3/28 and Sunday 3/29, at least for the stretch between the West Seattle Bridge and the south end of the Battery Street Tunnel. However, it also mentions that both directions of 99 will be closed between the north end of the tunnel and Valley Street from 10 pm Friday 3/27 to 5 am Monday 3/30 for utility work.
