UPDATE: Spokane Street Viaduct – First Avenue Off-ramp will reopen Sept. 19
The Seattle Department of Transportation shared an updated look at the Spokane Street Viaduct Widening Project and announced that most work is expected to be complete by early to mid October.
"The eastbound off-ramp at First Avenue S will reopen Wednesday morning, September 19. The same morning, First Avenue S between S Spokane and S Horton Streets will be returned to two travel lanes in each direction, and the eastbound stretch of surface S Spokane Street from East Marginal Way to First Avenue S will reopen.
The only project-related street closure over the coming week will be a modest one—the Tuesday, September 18, overnight closure of First Avenue S, from the on/off-ramp to the north side of the intersection of First Avenue and S Spokane for both north and southbound traffic. The First Avenue on-ramp to West Seattle will remain open.
These and other project related traffic impacts are outlined below.
