If you have traveled to a large unfamiliar city on the navigator, then you already know the situation, when by chance you pass a turn on a large transport hub. At junction named Harry Predzhersona in Los Angeles to miss your exit - is to lose half a day. A four-level structure was built in 1993 at the intersection of major highways I-105 and I-110. Also, through the interchange passes Metro line (the second level). This junction is considered to be the most difficult in the world.
As planned by the drivers must pass this interchange without stopping, and the need to give anyone else the way, no matter where they go and where directed. By the way, traffic jams there really is not seen, and if you know where to turn, the problems should arise. This isolation was captured in one of the scenes of the movie "Speed". Keanu Reeves and Sandra Bullock made her crazy jump on the bus with a bomb here.
