SDOT Transit Program

Public transit contributes to healthy neighborhoods. It encourages pedestrian activity, smart growth, and economic development. The City is committed to making transit a more efficient, affordable choice for a wider variety of trips. We’re building projects and planning for the future.

Transit Master Plan
In April 2012, the City Council approved and unanimously adopted the Transit Master Plan (TMP). The TMP provides a long-range vision for the future of transit in Seattle. Learn more about the Transit Master Plan

Transit Corridor Planning
The TMP prioritized several high-capacity transit (HCT) corridors throughout the city that will need more investments if we’re going to meet future demand. (click to enlarge map).

We’re currently working on five studies:

What is high-capacity transit (HCT)?


SDOT is building better public transportation infrastructure through projects that improve corridors and connections. The goals of these projects are to:

  • Help transit run faster and more reliably
  • Improve overall capacity to move people around the region
  • Improve transit connections and rider experience  

Seattle Streetcar
The South Lake Union Streetcar has been up and running since 2007. The First Hill Streetcar line is currently under construction and scheduled to begin service in 2014. For more information, visit the Seattle Streetcar website.

Priority Bus Corridors
We’re upgrading several key transit corridors, to expand RapidRide in Seattle. The Transit Master Plan also identified 16 corridors that form the backbone of the public transportation network, carrying high numbers of transit trips, showing the potential to generate many additional riders, connecting neighborhoods, and supporting sustainable growth.

Third Avenue Corridor

South Lake Union Transit Improvements

Spot Improvements
SDOT and Metro collaborate to implement targeted spot improvements around the city. These improvements utilize the same approach that drives the transit priority corridor projects, but spot improvements are lower cost and have a faster turn-around time. Bridging the Gap has helped fund a variety of projects like this, from a new queue jump at Columbia Street and Second Avenue to bus lanes on Battery Street and Wall Street.

Real-Time Information Sign (RTIS)

SDOT has developed a new tool in the form of real-time information signs (RTIS) that are located at city transit stops with high boarding activity. The signs provide up-to-the-minute estimates of incoming King County Metro and Sound Transit bus arrivals.

Arterial Asphalt and Concrete Projects

Arterial Asphalt and Concrete (AAC) projects are major reconstructions of arterial streets. These projects present excellent opportunities to cost-effectively improve transit, bicycle, and pedestrian facilities. Under the Complete Streets Ordinance, adopted in 2010, Seattle must consider all users in the design of road projects. This assessment includes bus riders, pedestrians, bicyclists, freight, and automobiles. For a complete list visit the AAC website. The following AAC projects include significant upgrades to bus stops and facilities:


Transportation Hubs

Opening of McGraw Square, 2011

Integrated, seamless transit systems rely upon hubs for smooth and reliable transfers between transit services. SDOT takes an active role to ensure that Seattle’s primary transit hubs are pedestrian friendly, safe and enjoyable places. 

The three key intermodal hubs in the Downtown area include:

  • Westlake
  • Colman Dock
  • King Street Station

Recent hub improvements have included the opening of McGraw Square which is part of the Westlake Hub. As a nexus of light rail, buses, the Seattle Center Monorail, and the South Lake Union Streetcar, Westlake Hub connects thousands of people to destinations across the region, every day. Visit the McGraw Square project website for details.

King Street Station


King Street Station is currently undergoing a $50 million renovation. The City teamed up with a variety of partners to restore the station, create a new pedestrian plaza on Jackson and much more. The work will ensure that King Street Station is a vital hub and gateway to Seattle for another hundred years.
