The South Access — Surface Street Connections Project completes final roadway work associated with the SR 99 tunnel and Alaskan Way Viaduct demolition projects, and builds new pedestrian and bicycle amenities that connect Seattle’s stadiums with the waterfront. This is the final project out of 30 in the Alaskan Way Viaduct Replacement Program. Much of this work could not be completed until the SR 99 tunnel and Alaskan Way Viaduct demolition projects were finished.
The work includes paving portions of First Avenue South and South Dearborn Street. Railroad Way South will become a plaza between Alaskan Way and Occidental Avenue South, creating a pedestrian corridor between the stadiums and the waterfront. A new east-west street, Charles Street, will provide local access between First Avenue South and Occidental Avenue South.
Construction began in July 2021 and is expected to conclude in summer 2023. First Avenue South and Alaskan Way South will be kept open for the vast majority of the work, and the project is not expected to require much night work. People travelling along First Avenue South near Seattle's stadiums may encounter lane closures and reductions, and occasional sidewalk detours.
1051 Building Demolition SEPA process
In fall 2022, WSDOT discovered that the building it owns at 1051 First Avenue South, Seattle WA 98134 contains serious structural deficiencies. Subsequent inspections determined that the building is unsafe for occupancy. WSDOT is now planning to demolish the building in 2023, and replace the existing sidewalk adjacent to the building along First Avenue South.
WSDOT has determined that this proposal will not have a probable significant adverse impact on the environment. An environmental impact statement (EIS) is not required under RCW 43.21C.030(2)(c). This determination was made based on review of the findings in the SEPA environmental checklist and supporting documents on file with the lead agency.
This DNS is issued under WAC 197-11-340(2). The comment period ended on March 21, 2023.

The $3.3 billion Alaskan Way Viaduct Replacement Program (AWV) is funded by state, federal and local sources. The South Access — Surface Street Connections project, using state funds only, is part of the $2.15 billion SR 99 tunnel project of the AWV Program.
The scope of the South Access - Surface Street Connections Project includes paving First Avenue South near Lumen Field, and build a new pedestrian plaza where Railroad Way South once ran between Alaskan Way and Occidental Avenue South.
This project is one of the 30 projects in the Alaskan Way Viaduct Replacement Program.
The City of Seattle is leading the rebuilding of the new Alaskan Way in the footprint of the old viaduct, which will connect to the new pedestrian plazas being built as part of this project.
