Overview

In 2001, the Downtown Seattle Association formed a Viaduct Task Force in response to the damage sustained to the Viaduct during the Nisqually earthquake and plans by the City and State to replace the structure. Now wrapped into the DSA’s Transportation Committee, the group has been active in every step of the Viaduct replacement process, encouraging the City to address critical emerging land use and urban design issues while serving as an advocate for Viaduct replacement scenarios that best address the needs of the Downtown Seattle community.
