Interstate 105 (Glenn Anderson/Century Freeway) and Interstate 110 (Harbor Freeway) interchange.
Massive maze of on-ramps, flyovers, light-rail, carpool lanes, and overpasses. Contains the Rosa Parks Metro Rail (green line) station.
Was once described in Metropolis magazine as the "largest public sculpture in the world".
Before the interchange was completed, it was used in filming the movie "Speed". The fifth level HOV lane was used; a ramp was added to give the bus extra height. http://en.wikipedia.org/wiki/Speed_(film)
