Interstate 105 is an 18.82-mile freeway located in the Los Angeles Metropolitan Area. Interstate 105 begins at California State Route 1 in El Segundo and terminates to the east at Interstate 605 in Norwalk. Interstate 105 is developed over the conceptual corridor of the Century Freeway which was originally part of California State Route 42. Interstate 105 was completed by 1994 and is one of the last major urban Interstates to have been developed.
Part 1; the history of Interstate 105
The development of Interstate 105 and the Century Freeway is heavily tied to what was California State Route 42. California State Route 42 was originally designated as California State Route 10. More on California State Route 42 and California State Route 10 can be found below:
On June 29th, 1956, the Federal Highway Aid Act of 1956 was signed into law on the Federal Level. The Federal Highway Aid Act of 1956 was the genesis point of the Interstate Highway System. California State Route 10 (CA 10) was subsequently renumbered to CA 42 during 1960 to avoid duplication with Intestate 10. CA 42 first appears on the 1961 Division of Highways Map.
Interstate 105 is probably most well-known from the 1994 action movie Speed and the infamous bus jumping a freeway exit gap scene.
