All bike routes on East Marginal Way S. and Alaskan Way S. will remain open during the nine-day closure of the viaduct, says the Washington State Department of Transportation.

During the closure, WSDOT will:

• Prohibit bicycle and pedestrian detours.

• Remove debris and other potential hazards, including draining large puddles.

• Add road signs alerting motorists to watch for bicycles in the road.

Bicyclists are urged to wear bright and reflective colors to ensure visibility to others.
