King County

King County is the largest county in Washington State by population, home to roughly 30% of the state's residents. It stretches from Puget Sound to the Cascade Range, encompassing the major cities of Seattle and Bellevue and their sprawling suburbs, as well as wide stretches of rural farmland and uninhabited mountain terrain.

Get in

By car

The major interstates are I-5, running north-south through Seattle to Snohomish County and Pierce County, and I-90, running east from Seattle through Bellevue and Issaquah to Snoqualmie Pass and Kittitas County. The notoriously congested I-405 splits off from I-5 at Tukwila in the south and Lynnwood in the north, serving Bellevue and the other cities of the Eastside. From the I-5/405 junction in Tukwila I-405 becomes SR-518 which continues west to SR-509 in Burien via Seattle-Tacoma International Airport.

By plane

1 Seattle-Tacoma International Airport, (SEA ^IATA), called "SeaTac" by locals, it connects Seattle to all regions of the U.S. and the world, especially with frequent transpacific routes but, also to Europe, Mexico and the Middle East as well. Competition is fierce and fares are low on service to the San Francisco Bay Area and Southern California with multiple airlines.

In addition to the above there are additional airports for general aviation and Kenmore Air at:

• 2 King County International Airport/Boeing Field (BFI ^IATA) which serves as an airport for cargo flights, general aviation, VIP flights, and Boeing test flights as well as Boeing manufacturing activities. It is also the location for the aviation museum. Commercial aviation is only with Kenmore Air.
• 3 South Lake Union Airport (LKE  ^IATA) is a base for Seaplanes which are another popular way to travel around Puget Sound with several airlines based out of Seattle including Kenmore Air serving areas all around Puget Sound and Canada and Harbour Air to Vancouver's Coal Harbour. Kenmore Air offers shuttle transfer from SeaTac to their terminal on the shores of Lake Union and King County International Airport (Boeing Field).

• 4 Renton Municipal Airport (RNT ^IATA), farther from downtown than Boeing Field but still closer than Sea-Tac Airport, is another option for general aviation, with a sea plane dock at the north end of the airport on Lake Washington known as Wiley Post Memorial Seaplane Base. This airport only has basic facilities and no terminal building, but customs and immigration facilities are available for international arrivals with prior arrangement. For travelers going up to Friday Harbor on the San Juan Islands 5 Friday Harbor Seaplanes offer tours and one way travel up from the Renton Municipal Airport in their seaplanes.

Has regional public transit routes including Sounder trains, Link light rail, and express bus in King County (e.g. Bellevue, Federal Way, Kent, Renton, Seattle), Snohomish County (e.g. Everett, Lynnwood) and Pierce County (e.g. Puyallup, Tacoma). (updated Jun 2023)

• Link light rail operates in Seattle, traveling north to Lynnwood and south to Angle Lake via Seattle-Tacoma International Airport on the 1 Line Train and from Redmond Tech Station to South Bellevue via downtown Bellevue on the 2 Line Train. Construction is underway to extend the 2 Line Train into downtown Seattle from the South Bellevue Station and from Angle Lake to Federal Way.

Outside of the immediate Seattle-Bellevue area, many routes operate only during weekday rush hours. Check your schedules in advance, and beware of holiday service cutbacks. All Sound Transit routes have route numbers that are in the 500s.

By car

All but essential for reaching the outermost suburbs and mountains. In addition to the interstates, major routes include SR-520, linking Seattle's University District to Bellevue and Redmond. On the south end, SR-18, a major freeway from I-5 (Exit 142) in Federal Way to I-90 (Exit 25) in Snoqualmie, east of Issaquah, through Black Diamond, Maple Valley and Covington; and SR-167, from Exit 2 of I-405 in Renton to Puyallup via Kent, Auburn (Jct SR=18), Pacific and Sumner. On the north end SR-522 branches from I-5 (Exit 171) to US-2 in Monroe via Lake City Way in N Seattle, Bothell, and Woodinville (Jct I-405). SR-522 goes around the northern shores of Lake Washington.

Traffic congestion is a major problem in the Puget Sound area on all freeways and major roads. Avoid traveling during rush hour if you can, particularly along I-5 and across the Lake Washington bridges.

Lake Washington is crossed by two floating bridges: the I-90 bridge is free, but the SR-520 bridge charges a toll that varies by the time of day. There are no toll booths: unless you have a transponder, your license plate will be recorded and a bill will be mailed to you automatically in a few weeks. The long detour around the lake in either direction will usually waste far more time than you'll save in toll money.
