The Santa Ana Freeway is one of the principal freeways in Southern California, connecting Los Angeles, California and its southeastern suburbs. The freeway begins at the four level Bill Keene Memorial Interchange complex in downtown Los Angeles, signed as U.S. Route 101. From there, it proceeds one mile east to the East Los Angeles Interchange where it takes the designation of Interstate 5. Its alignment then generally goes northwest to southeast towards its junction with the San Diego Freeway, Interstate 405 (I-405) (informally referred to as the El Toro Y), in Irvine.

North of the East Los Angeles Interchange complex, Interstate 5's name changes to the Golden State Freeway. South of its junction with the I-405, its name changes to the San Diego Freeway. (Interstate 405 ends at this junction.)

An abundance of landmarks, most importantly (Disneyland and Angel Stadium of Anaheim) in Anaheim, along the Orange County portion of its route combines with a severe bottleneck beginning at the Los Angeles County border (shrinking from 12 to 6 lanes) to make it one of the most congested freeways in Southern California. The infamously busy intersection of the Santa Ana, Garden Grove, and Orange freeways in southwestern Orange is nicknamed the Orange Crush.

[edit] History

The Santa Ana Freeway is a bypass of the original state highway from Los Angeles to Santa Ana, which passed through Whittier and mostly became SR 72 in the 1964 renumbering. Southeast of Santa Ana, this earlier highway, added to the state highway system in 1910 as Route 2, generally followed the present freeway from Tustin past East Irvine to El Toro.^[1] This route was marked as part of US 101 in 1928.^[2]

In 1933, the state legislature added a number of routes to the state highway system, including two that later formed parts of the Santa Ana Freeway. Route 166 began at the new Route 172 (now SR 60), at the corner of Indiana and Third Streets, and headed south on Indiana Street and east and southeast on Mines Avenue (Olympic Boulevard) and Anaheim-Telegraph Road to Route 171 (now SR 39) at the intersection with Los Nietos Road near Santa Fe Springs. Route 174 began at Route 60 (now SR 1) and followed Manchester Avenue and Firestone Boulevard (then under construction alongside the Southern Pacific Railroad's Santa Ana Branch) to Route 2 (Anaheim Boulevard) in southern Anaheim. A second piece began further southeast on Route 2, where it turned east on Chapman Avenue, and followed the shorter Santa Ana Boulevard diagonally to Route 2 (Main Street) in northern Santa Ana.^[3][4] In 1934, Route 166, except on Indiana Street, was marked as part of Sign Route 6 (which continued along Route 171 to Buena Park), and the entire length of Route 174 became Sign Route 10.^[5][6] (SR 6 was renumbered to SR 26 in 1937, when US 6 entered California;^[7] SR 10 was soon truncated to Anaheim Boulevard, as US 101 had moved from Route 2 to the shorter Route 174 in Santa Ana.^[8])

A U.S. Route 101 Bypass was created by 1941, beginning at the intersection of Routes 166 (Indiana Street, soon moved to Downey Road^{[citation needed]}) and 2 (US 101 along Whittier Boulevard), and following Routes 166 and 174 to Route 2 (US 101) in Anaheim. The connection between Routes 166 and 174 was made via Route 168 (Rosemead Boulevard, then and now SR 19). This resulted in SR 10 being truncated further, to the intersection of Firestone and Rosemead Boulevards, though SR 26 continued to extend east to Buena Park.^[9][10][11]

A freeway connecting downtown Los Angeles with Orange County was planned by that county by 1939,^[12] and was included in A Transit Program for the Los Angeles Metropolitan Area, published that year by the Metropolitan Transportation Engineering Board.^[13] To allow for its construction by the state, the definition of Route 166 was modified in 1941, changing the southeast end to Route 174 near Norwalk; at the same time, the northernmost piece was changed from Indiana Street to Downey Road.^[14]

The entire Santa Ana Freeway began construction in 1947 and completed in 1956. Originally it was signed as US 101 before the segment of the 101 between the East Los Angeles Interchange and the United States–Mexico border in San Ysidro, California was decommissioned in favor of Interstate 5. It was approved as as a chargeable interstate in 1961. The Santa Ana Freeway and also portions of San Diego Freeway (before the freeway was built) south of El Toro Y went up changing the U.S. 101 signs to Interstate 5 in 1964, including full length of Golden State Freeway which was originally signed as US 99.
