Content: The Washington State Department of Transportation has made improvements to Interstate 405 in Bellevue to make it a less-congested drive. But I-5 from Northgate is different. Just south of Northeast 65th Street, three lanes start to spit a large volume of cars onto the highway, one on the left and two on the right. The two lanes on the right – the Northeast 50th and 45th Street exits – create a choke-point because some of the merging cars are headed for the State Route 520, accessible by a left-sided exit just past the Ship Canal Bridge. Those drivers – most of them headed for the Eastside – must cut across four lanes of traffic and the result is a slowdown felt clear past Northgate, four miles away. This move has a name: a C-class weave. As cars enter the congested highway, drivers already on the road start to change lanes, trying to get away from the hoard of new arrivals.
