this transition must exit at the Pomona Freeway's interchange with the Long Beach Freeway (I-710) located to the east, head south, and then transition to the Santa Ana Freeway at the interchange between those two freeways. There is no direct connector from the southbound Santa Ana Freeway (US 101) to the northbound Golden State Freeway (I-5) (and vice versa); travelers wanting to make this transition must exit at the Four Level Interchange with the Arroyo Seco Parkway (SR 110, northeast from this interchange) located to the west, head northeast, and then transition to the Golden State Freeway at the interchange between those two freeways. There is no direct connector from the southbound Santa Ana Freeway (US 101) to the westbound Santa Monica Freeway (I-10) (and vice versa); travelers wanting to make this transition must exit at the Four Level Interchange with the Harbor Freeway (SR 110, southwest from this interchange) located to the west, head southwest, and then transition to the Santa Monica Freeway at the Dosan Ahn Chang Ho Memorial Interchange. Further complication is caused by the varying designs of each intersecting freeway and their related transition roads. Some have four lanes and are relatively straight and wide, while others have one lane, are narrow, or have curves with tighter radii or cambers. Traffic congestion is thus exacerbated as vehicles moving at high speed on the wider transition roads try to merge with slower moving vehicles coming from the narrow transition roads. History Construction of the began in 1961. The enormity of the structure and the complexity of its many routes called for a $17,000 blueprint model of the highway. It has thirty-two bridges and twenty walls with of earth being excavated. The project laid of concrete pipe, used of concrete and of reinforcing and structural steel. In popular culture Although not commonly called such by residents and other reporters, the freeway intersection was often called "Malfunction Junction" by former KNX traffic reporter Bill Keene, because of its complicated interchange structure. The interchange has also been referred to as "The Beast" L.A. Interchange and the "East Delay" Interchange, names attributed to KNX's Jim Thornton, as well as the "Nickel/Dime" during traffic reports.
