SEATTLE – Both directions of the State Route 99 tunnel in Seattle will close the first two weekends in October for its first six-year inspection. The tunnel opened to travelers in February 2019 to replace the Alaskan Way Viaduct and provide safety and mobility improvements along Seattle's central waterfront.
