Seattle viaduct to shut down for 9 days in October

SEATTLE — The Transportation Department is holding a news conference Monday in Seattle to announce plans to shut down the Alaskan Way Viaduct for nine days in October.

Crews will demolish a section of the viaduct near Safeco Field and CenturyLink Field and build a detour.

The Seattle Times reports it's part of $3 billion project to replace the aging viaduct. The section of Highway 99 south of downtown will remain above ground, and a tunnel will take a section under downtown Seattle.
