Interstate 405

Los Angeles bypass highway

Interstate 405 refers to two major American highways—one in Southern California running through Los Angeles's west side, the other in the Seattle area.

The LA 405 is notorious for heavy traffic and appears constantly in local conversation: Take the 405 to the 10.

In California, interstates take the definite article; elsewhere they typically don't: I took 405 north.
