Sound Transit 2: A Mass Transit Guide
The Regional Transit System Plan for Central Puget Sound
On July 24, 2008, the Sound Transit Board of Directors adopted a 15-year regional mass transit plan, and
unanimously approved placing it on the November 2008 ballot. The plan was approved by voters in the Sound Transit district. The adopted plan is detailed below.
Introduction
Sound Move achievements:

New light rail from Downtown Seattle to Sea-Tac
Airport opens 2009; extension to UW opens 2016

74 miles of Sounder commuter rail with 10 stations

ST Express bus routes offer all-day, two-way service
around the region

Tacoma Link light rail connects Tacoma Dome Station
to Downtown Tacoma

More than $800 million invested in transit centers,
HOV direct access ramps and park-and-ride lots

PugetPass easy transfer fare system
Sound Transit proposes to improve and expand the regional mass transit system. The agency has
been working since 1996 on the first phase of a regional mass transit system in the Central Puget
Sound region that includes Link light rail, Sounder commuter trains and ST Express buses. This
initial phase, called Sound Move, was approved by voters in 1996 in response to burgeoning
growth and traffic problems.
Sounder commuter trains currently operate in a 74-mile corridor from Everett to Tacoma, with
construction of an eight-mile extension to Lakewood underway. ST Express buses operate on
every major highway in the region. Link light rail serves Downtown Tacoma, and it will open for
service between Seattle and Sea-Tac International Airport in 2009. Together, these services carry
more than 14 million riders a year reliably around the region to jobs, shopping, school, sporting
events and other places they need to go.
Construction of the Link light rail extension between Downtown Seattle and the University District
is expected to begin in late 2008, with service to start in 2016.
Even with those investments, however, improving transportation continues to be one of the
biggest challenges facing this region.
Another one million people are expected to call this region home in the next 25 years. That's
about a 30 percent increase in population and is more than the current combined populations of
Seattle, Bellevue, Everett and Tacoma. Put another way, the population of the Central Puget Sound
region is growing by more than 40,000 people per year.
By the year 2030, growth will lead to a 35 percent increase in employment and a 30 percent
increase in vehicle travel in the region. By 2030, the typical commuter could spend nearly an
entire work week of additional time stuck in traffic. Weekday rush hour could last from breakfast
through dinner, strangling the movement of traffic and freight, jeopardizing our economy, and
hurting the environment.
With a strong mass transit foundation in place and more growth on the way, additional
investment is needed to ensure mobility for people and to help the Central Puget Sound region's
transportation system run smoothly. An expanded mass transit system that builds on what we
have is more important than ever.
In response, Sound Transit is proposing a plan that builds on the Sound Move program called
Sound Transit 2. The Sound Transit 2 Plan (ST2) would expand the existing light rail system to
serve three major travel corridors. Link light rail would extend from North Seattle into Snohomish
County, across Lake Washington into East King County, and south of Sea-Tac International Airport
to Federal Way. ST2 would also expand Sounder commuter rail and ST Express regional bus
service significantly. A map showing ST2 Regional Transit System Plan improvements can be found
here.
The ST2 Plan was developed through an open public process over a four-year period. During
that period, Sound Transit coordinated closely with cities and counties and conducted substantial
public outreach. With more jobs and people on the way, the time is now to continue building our
transportation future.
