    SEATTLE - As demolition nears its home stretch, crews will remove the section of the Alaskan Way Viaduct over South Dearborn Street.

    Beginning Thursday, the section of Dearborn that spans Alaskan Way to First Avenue will be closed for 10 days and First Avenue South will be narrowed to two lanes on either side of the intersection. 

    Crews will remove the viaduct segment that spans the road near First Avenue South. The section will be removed from both the north and the south, meeting in the middle.

    Southbound SR 99 Metro bus service in the Pioneer Square area is rerouted off of First Avenue South. A dozen routes have already been moved to Second and Fourth avenues.  Read more here

    WSDOT asks drivers to plan ahead for the closure, including exiting SR 99 at Spokane Street or using public transit.  

    Dearborn is scheduled to reopen Sept. 22.

    Demolition will continue into next month around Marion Street.
