Aerial View of Highway Tunnel Portal, Retention Pond, and Sea-Tac Airport Runway Under Construction

Aerial photograph showing a highway with a tunnel portal, a rectangular concrete structure with green equipment units, a newly constructed retention/settling pond with orange sandy margins, and an airport runway in the background. The site appears to be an active construction project, likely stormwater or noise mitigation infrastructure, situated between a major freeway and an airport airfield.
