Getting to events will be a challenge this weekend; SR 99 closures mean plan ahead and leave early
information from SDOT
Getting around in Seattle this weekend and early next week will be complicated by the closure of State Route 99, including the Alaskan Way Viaduct, to accommodate the demolition and replacement of the section of this highway that crosses above Broad Street.
State Route 99 way will be closed to both directions of traffic from the West Seattle Bridge to Valley Street from 10 p.m. Friday until 5 a.m. Monday. The exception will be to accommodate Seahawk traffic leaving CenturyLink Field on Friday night. Northbound SR99 will be open from South Royal Brougham Way and southbound SR 99 will be open from Columbia Street until midnight. Then, from 5 a.m. on Monday through 5 a.m. on Wednesday, the State Route 99 will be closed to both directions of traffic from the south end of Battery Street tunnel to Valley Street.
If your weekend plans include traveling in the Pioneer Square, lower Wallingford or Fremont, or Alki areas, you might want to look into traffic impacts of special events in those neighborhoods (see below).
