There’s our first official C-class weave person, who made all four movements.” The Camry sped up over the Ship Canal Bridge and made for the exit, leaving disorder in its wake.

No Design Workaround
The designers of I-5 in the 1950s did not foresee the wrinkle with their plan. When they designed this section of I-5, they didn't know there would a 520 bridge. In the decades before Microsoft colonized the Eastside, it was not certain that I-405 would be anything other than a Seattle bypass route. Interstate 90 was already going to cross Lake Washington, so it was thought that there would be no need for a second bridge.
