February 2019 marks the beginning of a new period in downtown Seattle transportation mobility, with the permanent closure of the SR-99 Viaduct and opening of the SR-99 Tunnel in early February.

Arena construction will start soon. For more information on this transformational project, visit: New Arena at Seattle Center.
