Sound Transit board selects "most promising" Link light rail routes for further study

Publish Date

The board of Sound Transit - The Central Puget Sound Regional Transit Authority - today selected the 18 most promising potential routes for the central Link light rail system that will connect the cities of Seattle, Tukwila and SeaTac. Nearly 40 potential routes were initially considered, many of them suggested by local communities and citizens for the 24-mile all-electric system. A separate analysis of routes and stations is being conducted for Tacoma's 1.6 mile Link light rail system. 

The 18 potential routes will be studied for the draft Environmental Impact Statement scheduled to be completed by November 1998. For study purposes, the central Link light rail system is divided into six segments with each section having at least two potential routes for further study.  

A briefing book outlining these routes is available from Sound Transit. Please contact Clarence Moriwaki at (206) 689-4946 or e-mail at

Sound Transit is on track to implement a three-county region-wide transit system plan known as Sound Move. Approved by voters in 1996, Sound Move will be a seamless blend of three transportation systems: Sounder commuter rail, running 81 miles from Everett to Tacoma/Lakewood; Link light rail, a 24-mile all-electric system connecting the cities of Seattle, Tukwila and SeaTac and a 1.6 mile system connecting downtown Tacoma with the Tacoma Dome commuter station; and Regional Express, a bus transit system that will connect the major metropolitan areas of Bellevue, Everett, Tacoma and Seattle with numerous cities and communities with 20 new, fast, limited-stop bus routes.
