Interstate 405 (Washington)

Interstate 405 (abbreviated I-405, and colloquially referred to as 405 or four-oh-five) in Washington is a stretch of freeway that bypasses Seattle east of Lake Washington. The northern terminus is in Lynnwood and the southern terminus is in Tukwila. The highway runs through what has since become the "Eastside" technology center of Bellevue and Kirkland, making it an often congested commuter path. I-405 is known for its meandering "S-curves" through Renton. It intersects with Interstate 90 and a number of major state routes. Interstate 405 was laid over Secondary State Highway 2A.
