The two upcoming projects are the SR 520/I-5 Express Lanes Connection Project and the AWV South Access Surface Street Connections Project. Construction for both projects is slated to begin in spring/summer 2021. The meeting will include a WSDOT presentation and time for Q&A.

Needs & benefits

This project completes final roadway work around the south portal of the SR 99 Tunnel, and builds new pedestrian and bicycle amenities that connect Seattle’s stadiums with the waterfront. The work includes paving portions of First Avenue South and South Dearborn Street, and turning Railroad Way South into a pedestrian plaza that links Seattle's stadiums with the central waterfront. Much of this work could not be completed previously due to SR 99 Tunnel and Alaskan Way Viaduct Demolition work.
