WSDOT presentation by Senior Transportation Planner Thomas Noyes to the SDOT Freight Advisory Board on August 15, 2017, covering the Puget Sound Gateway Program SR 509 Completion Project and SR 167. Topics include direct freight links from Port of Seattle and Port of Tacoma to regional distribution centers and Eastern Washington, direct access to Seattle-Tacoma

A July 2017 presentation by the Washington State Department of Transportation outlines the Puget Sound Gateway Program's SR 509 Completion Project, which aims to build new freeway connections linking the region's major ports and Seattle-Tacoma International Airport to surrounding communities and Eastern Washington. The project includes plans for tolling to help fund construction and is intended to improve freight movement, airport access for passengers and air cargo, and regional economic development.

The Highline Forum held on July 26, 2017, at SeaTac City Hall brought together community stakeholders, city officials, and representatives from WSDOT and the Port of Seattle to discuss key regional topics including the SR 509 Puget Sound Gateway Program, aircraft altitude concerns, and air quality initiatives near Sea-Tac Airport. Presentations were delivered by Port of Seattle staff covering noise programs and environmental initiatives, alongside updates on SeaTac's economic development. The meeting provided a public forum for emerging issues and planning for future discussions on airport-related impacts to surrounding communities.

This document contains the agenda for a Highline Forum meeting held on May 25, 2016, at the Normandy Park Community Club, focused on the theme of transportation. The meeting featured a presentation by Wendy Taylor of HNTB on the SR 509 Puget Sound Gateway Program, a highway corridor project in the Seattle area near Sea-Tac Airport. The forum brought together local officials, including Normandy Park Mayor Jonathan Chicquette, to discuss regional transportation updates and emerging issues affecting the Highline area.

The Highline Forum is a collaborative body representing Southwest King County cities, schools, and the Port of Seattle that meets to share information and work on regional initiatives. A March 27, 2013 meeting held at SeaTac City Hall focused on transportation topics, including the SR 509 Extension/I-5 Improvement Project and a status update on the Port of Seattle's Part 150 noise study, which directly relates to Sea-Tac Airport noise mitigation policy. The Forum operates by consensus and is governed by procedures that assign the Port of Seattle as the lead disseminator of all Forum-related information.

This aerial map depicts Seattle-Tacoma International Airport (Sea-Tac) and its surrounding communities of Burien and SeaTac, showing the airport's runway layout including runways 34L and 34C, along with key roadways such as SR 99, SR 509, and various access roads. Highlighted routes in purple and orange appear to mark designated corridors or boundary lines relevant to airport planning or noise study areas. The map provides a geographic reference for understanding the airport's footprint and its relationship to neighboring residential and commercial zones.

This January 2003 Final Environmental Impact Statement evaluates proposed highway improvements in southwest King County, Washington, including an extension of SR 509 and upgrades to I-5 between South 210th Street and South 310th Street to improve regional access to Seattle-Tacoma International Airport. Three build alternatives and a No Action Alternative are assessed, with the SR 509 extension designed to accommodate two general purpose lanes and a center high-occupancy vehicle lane in each direction. The project was jointly prepared by the Federal Highway Administration, Washington State Department of Transportation, Port of Seattle, King County, and the Cities of SeaTac and Des Moines.
