Department of Transportation keeps people moving
Our mission is to improve the quality of life for people in King County by providing mobility in a way that protects the environment, helps manage growth, and reduces traffic congestion.
The Department of Transportation is made up of five divisions and the Director’s Office. Some 5,000 employees provide a wide variety of services for people who travel in King County. The department also works in partnership with many cities in the county as well as with subregional, regional, and state groups to integrate and improve transportation services.
The Director’s Office provides overall leadership, coordination, and support for the department of transportation’s services.
The office leads several department initiatives such as developing strategies to respond to emergencies, reducing greenhouse gas emissions, and planning transportation improvements to meet the needs of our growing population.
Metro Transit Division
King County Metro Transit offers bus, vanpool, and paratransit services. One of the 10 largest bus systems in the nation, Metro operates 220 bus routes throughout the county, with nearly 10,000 bus stops and 132 park-and-ride facilities connecting riders with those routes. Customers consistently give Metro high marks for friendly, on-time service.
Metro is recognized as a leader in green practices with its use of clean-burning fuels, electric trolleys, and hybrid buses. The agency provides extensive commute trip reduction services to 480 major employers and sells transit and commuter-van passes to more than 2,000 employers.
Road Services Division
The Road Services Division maintains about 1,500 miles of roads and 181 bridges in unincorporated areas of King County. This road system supports more than one million trips each day, including people traveling to work, school, and recreation; businesses and farmers delivering goods and services; and police and fire crews responding to emergencies. About half the trips on the high-volume roads originate not only in cities but in other counties.
In addition to supporting travel, the road right-of-way also serves as a pathway for water, sewer, stormwater, energy, and communication utilities.
Designated by the National Air Transportation Association as one of the country’s “100 most needed airports,” King County International Airport at Boeing Field is owned by the citizens of King County and receives no general tax dollars. It was established in 1928 by voters and continues to be vital to our local, regional, and state economies. The airport supports 300,000 aviation operations (takeoffs and landings) each year, and is home to dozens of aviation-related businesses, including the world-renowned Museum of Flight.

It also provides accounting for the county’s equipment, tools, supplies, and other capitalized assets, and disposes of all surplus property.
The division has been an industry leader in building a green fleet and using clean fuels. It is a leader in a consortium of public agencies formed to purchase hybrid electric vehicles.
The Marine Division manages the King County Water Taxi, which provides passenger-only ferry service between Vashon Island and downtown Seattle and between West Seattle and downtown Seattle.
