Sound Transit Commuter Rail

Seattle, Washington

Increases mobility in Puget Sound

Cities across the country are looking to multimodal solutions to traffic congestion, including the addition and expansion of passenger rail. Since 1996, Sound Transit’s 82-mile, 12-station commuter rail system has delivered mobility to residents of Central Puget Sound. Service runs from Seattle to Tacoma and Seattle to Everett in northwest Washington.

HNTB provided preliminary and final design of regional express bus facilities, transit centers, commuter rail track and station design, as well as construction management and reviews for development and expansion of the system. King Street Station is the system’s major downtown terminal and part of a larger complex serving Amtrak and BNSF Railway freight trains.
