The contractor working to widen the Spokane Street Viaduct (the raised roadway that connects I-5 to the West Seattle Bridge) plans to close the structure’s westbound lanes just west of I-5 for three nights: September 7, 8 and 9. To complete necessary work, crews will also close First Avenue S at S Spokane Street overnight from September 6 through 10. Details are as follows:
- Westbound Spokane Street Viaduct closed September 7, 8 and 9
10 p.m. each night until 5 a.m. the next morning
- First Avenue S at S Spokane Street closed September 6 – 10
9 p.m. each night until 5 a.m. the next morning – September 6 & 10
11 p.m. each night until 5 a.m. the next morning – September 7-9
During the viaduct work, southbound I-5 traffic will be directed to the S Forest Street exit to access surface streets. Northbound I-5 traffic and westbound traffic from Columbian Way will be detoured to surface streets at 6th Avenue South. Motorists can still use southbound SR-99 to access the high-level West Seattle Bridge, or can access the low-level Spokane Street Bridge from East Marginal Way South.
