Interstate 105 (abbreviated I-105, and colloquially referred to as The 105 [pronounced the one-oh-five]) is an Interstate Highway in southern Los Angeles County, California that runs east–west from near the Los Angeles International Airport (LAX) to Norwalk. It is officially known as the Glenn Anderson Freeway for the Democratic California politician who advocated its construction. I-105 has also been referred to as the Century Freeway.[3][4][5][6]

This route is part of the California Freeway and Expressway System.[7]

Route description[edit]

The California Streets and Highways Code defines Route 105 as "from Pershing Drive near El Segundo to Route 605," but Caltrans never constructed the segment from Sepulveda Boulevard to Pershing Drive. Motorists can continue west via Imperial Highway over conventional roadway to Pershing Drive, but it is not part of Route 105 nor is it under state maintenance.

The 105 begins at Sepulveda Boulevard (State Route 1) on the southern edge of Los Angeles International Airport (LAX), adjacent to the city of El Segundo. It proceeds generally eastward from there on, crossing the Los Angeles and San Gabriel Rivers before terminating just east of the San Gabriel River Freeway (Interstate 605) in western Norwalk.

The freeway stops short of intersecting with the Santa Ana Freeway (Interstate 5), its parent interstate. Instead, the primary lanes of I-105 terminate at an at-grade intersection with Studebaker Road.

Much of the length of the Century Freeway runs parallel to Imperial Highway.

The Green Line (Los Angeles Metro) runs in the median of I-105 for the majority of its route from Redondo Beach to Norwalk.

History[edit]

Interstate 105 was an integral part of a Caltrans 1960s master plan for the Southern California freeway system, but did not open until 1993. Many factors contributed to the delay. The growth of the environmental movement in the 1960s created resistance to new freeway construction. Fiscal difficulties brought about by the 1971 Sylmar earthquake and the California tax revolt of the late 1970s further hampered Caltrans' construction efforts.[8]

However, the major source of resistance to the freeway's construction was community opposition and the side effects of these demands. By the early 1970s, most of the areas in the freeway's path (and thus slated to be demolished) were predominantly African-American. Resentment over previous freeway projects' effects on other black communities resulted in significant modifications to the original route. Most cities along the way, weary of the noise and visual blight created by elevated freeways, demanded that the route be built far below grade in a "trench." Also another source for resistance to the freeway's construction was that much of the areas along the I-105 path was going to be built in low income, high crime neighborhoods, which also delayed the freeway's construction until the crime in the areas went down.

After construction began in the 1980s, failure to perform a full survey of the area's groundwater deposits, combined with the 20–30 foot below-grade trench through the city of Downey, resulted in buckling and cracking along the eastern portions of the route. At one point a large sinkhole opened in the Bellflower Boulevard on-ramp. This resulted in construction of an elaborate pump system along the freeway between the interchanges with I-710 and I-605.

Norwalk, opposed to the freeway's proposed route through the center of the city, blocked the route from reaching its intended terminus at the (Interstate 5); however, Caltrans had already decided to abandon that section due to the inability of the severely congested Santa Ana Freeway to accommodate any more traffic. The freeway eventually replaced Manchester Avenue and Firestone Boulevard (both State Route 42), which were roads roughly parallel to the freeway.

The family home of Dennis Wilson and his brothers Brian and Carl, founding members of the highly successful Beach Boys rock band, was demolished in the mid-1980s to make way for the freeway. A California Historic Landmark marks the site of the former home.

Throughout the difficulties, Congressman Glenn M. Anderson (D-San Pedro) tirelessly advocated for the route's construction, touting its possibilities for congestion relief along Century, Manchester, and Firestone Boulevards and the Imperial Highway; it succeeded in these tasks, as well as relieving pressure on the Santa Monica (I-10) and San Diego (I-405) Freeways for travelers between Downtown Los Angeles and LAX. After Anderson's death in 1994, Caltrans honored him by renaming the freeway in his honor. However, the route's original name, "Century Freeway", is still used on a number of maps.

Another important figure in the freeway's history was Harry Pregerson, a United States federal judge who presided over the lawsuit concerning the freeway's construction and chose to continue presiding over the case despite being promoted to a higher level court.[9] The interchange with Interstate 110 is named the Judge Harry Pregerson Interchange in his honor.[10]

The freeway was originally signed with El Segundo as its westbound control city; however, in recent years, many of the El Segundo signs have been replaced and/or covered with "LAX Airport" signage due to the western terminus' proximity to Los Angeles International Airport.

Shortly before opening, filmmakers had access to use the empty freeway for a number of weeks to film the 1994 motion picture Speed.

Previously, the I-105 designation has been used for U.S. Route 101 (the Santa Ana Freeway) from I-5 (the Golden State Freeway) at the East Los Angeles Interchange to the connection to I-10 (the San Bernardino Freeway; this connection had been I-110); it went back to U.S. 101 in 1968.[11]

Exit list[edit]

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see the list of postmile definitions).[12] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Los Angeles County.
