SR 520 Online Open House

Welcome

Welcome to our online open house regarding the upcoming Portage Bay Bridge and Roanoke Lid Project. The open house also includes information on the SR 520/I-5 Express Lanes Connection Project.

The purpose of this website is to share the latest design concepts for the Portage Bay project and solicit public feedback on them – building on previous SR 520 design outreach.

This open house will remain open until October 2019. In addition, we hosted an in-person open house in June and will hold another one in the fall. Also, we held three topic-specific community stakeholder workshops this summer — in July, August and September — and are having in-depth coordination with the Seattle Design Commission. We periodically update this website as new information is available; the latest updates followed our Sept. 12 community stakeholder workshop.
