Viaduct in Seattle closes today, sending travelers scurrying for other routes; here's some help
The Viaduct carrying Highway 99 over the Seattle waterfront closes today (Friday) at 7:30 p.m. for nine days as part of its replacement project.
That busy stretch of highway is used each day by 110,000 drivers, who will have to find an alternative route or alternative way to get to their destination, such as a bus or train.
The Washington state Department of Transportation is encouraging drivers to plan ahead, get familiar with commute options and allow extra time to reach their destinations. Interstate 405 through Renton could see higher volumes as commuters and others from the south seek an alternative to I-5.
• Northbound SR 99 between the West Seattle Bridge and South Royal Brougham Way will be closed around-the-clock beginning at 7:30 p.m. Friday, Oct. 21 to 5 a.m. Monday, Oct. 31.
• Northbound SR 99 between the South Royal Brougham Way on-ramp and the Battery Street Tunnel will open from 5 a.m. to 7 p.m., Monday through Friday, and for special events at CenturyLink Field.
• Southbound SR 99 between the Battery Street Tunnel and West Seattle Bridge will be closed around-the-clock beginning at 7:30 p.m. Friday, Oct. 21 to 5 a.m. Monday, Oct. 31.
The state has almost finished the first of two side-by-side bridges that will replace the viaduct’s southern mile. Workers will begin demolishing part of the viaduct. When SR 99 reopens to traffic on Oct. 31, both directions through SODO will travel on the new bridge.
After Oct. 31 the state will finish demolishing the viaduct’s southern mile without disrupting traffic on SR 99 and begin building the second new bridge.
During the nine-day closure the state will finish building a four-lane bypass to connect the viaduct’s central waterfront section to the new SR 99 bridge and build a new southbound SR 99 off-ramp to South Atlantic Street. The existing ramp to South Royal Brougham Way will close.
