Interstate 405 (I-405) - North-South Bypass of Seattle
I-405 runs through the "Eastside" technology coordinator of Bellevue and Kirkland. It connects with major state routes, Interstate 90 and Interstate 5.
The highway goes through two counties: King and Snohomish. On the South end of the freeway is in Tukwila while the northernmost terminus is in Lynnwood.
The Washington State Department of Transportation has a master plan for I-405 improvements to enable traffic of 800,000 daily to run smoothly. The master plan includes creating vanpools, increasing transit service and adding more park-and-ride spaces along the freeway. Click here for more information.
