Ribbon Cutting Ceremony for new Roadway

A Ribbon Cutting Ceremony was held on August 9, 2017 to commemorate the substantial completion of construction for the Connecting 28th/24th Avenue
South Project. The Mayor and several City Council Members joined with dignitaries from the Washington State Department of Transportation, Freight Mobility Strategic Investment Board, Transportation Improvement Board (TIB), Port of Seattle, Sound Transit, and the City of Des Moines to celebrate the completion of this much anticipated project.

This project completes a a new principal arterial road corridor between South 188th Street in SeaTac and South 216th Street in Des Moines that will help relieve congestion on International Boulevard (SR99).  The new road will also provide access from the south to both Sea-Tac International Airport, the newly opened Sound Transit Angle Lake Light Rail Station and its 1000-plus stall parking garage.  In addition, the new road provides access to businesses in the Des Moines Creek Business Park and opens access to large tracts of property for development.  Local officials estimate that over 4 million square feet of new development can be facilitated due to the completion of this principal arterial road corridor.  Over the next 20 years, this corridor will help support development resulting in approximately 15,500 jobs and a projected total direct economic impact of $32,6 Million for the City of SeaTac.

The $14 Million construction project was jointly funded by the City, the Port of Seattle, Sound Transit, the State of Washington Department of Transportation, Freight Mobility Strategic Improvement Board, and The Transportation Improvement Board. Restoration and landscaping work is still being completed.  It is expected that the new roadway will be open for use by the public in late August 2017.
