A Seattle Department of Transportation (SDOT) Roadway Structures crew will perform a regular maintenance n inspection of the deck of the Spokane Viaduct east bound on Sunday morning, October 13. The work, which will take place between 6 a.m. and 11 a.m., will require lane closures eastbound on the Viaduct between E Marginal Way and the I- 5 ramps. Two lanes will be closed at a time for the inspections. Work will begin with the closure of the two left lanes and then those will reopen and the two right lanes will be closed. The on-ramps to SR 99, the off-ramps to First Avenue S and Fourth Avenue S as well as the I-5 on ramps will remain open throughout the operation. Motorists should plan on slowing through the work zone.
