Northbound Interstate 405/San Diego Freeway reaches Exit 45A, Junction Interstate 105/Glenn Anderson (Century) Freeway. Interstate 105 is the last new Interstate highway built in the Los Angeles area (opened in 1993), pending completion of the proposed but often-delayed Interstate 710 extension north to Pasadena. Note that the control city for the Interstate 405 pull-through sign was changed from Santa Monica to LAX Airport. Photo taken 03/25/07.
The Interstate 105/Century (Glenn Anderson) Freeway interchange is located just southeast of Los Angeles International Airport (popularly known as "LAX," which is the three-letter abbreviation for the airport, much as Baltimore-Washington International is abbreviated and popularly known as "BWI"). The segment of Interstate 405 between Interstate 105 and Interstate 10 is almost always very busy, and traffic jams are frequent through this stretch. This sign along northbound points to part of the reason why: LAX. Photo taken 03/25/07.
This mileage sign provides the distance to the next three exits along Interstate 405/San Diego Freeway north: Exit 45B, Imperial Highway/Los Angeles International Airport; Exit 46, Century Boulevard; and Exit 47, Manchester Boulevard (former California 42). There is no direct freeway connection to the airport. Note that the distant interchange complex is for Interstate 105. Photo taken 03/15/08.
Northbound Interstate 405/San Diego Freeway approaches Exit 45B, Imperial Highway to Los Angeles International Airport (0.25 mile). Photo taken 03/25/07.
Northbound Interstate 405/San Diego Freeway reaches Exit 45B, Imperial Highway to Los Angeles International Airport. The next offramp connects the freeway to Exit 46, Century Boulevard. Interstate 405 next passes through the stack interchange with Interstate 105. Photo taken 03/25/07.
The next two exits connect Interstate 405 to Hollywood Park Race Track. The track is located east of Interstate 405 in the city of Inglewood, bounded by Century Boulevard on the south, Prairie Avenue on the west, and Pincay Drive on the north. Photo taken 03/25/07.
Northbound Interstate 405/San Diego Freeway reaches Exit 46, Century Boulevard to Los Angeles International Airport (LAX).

This mileage sign provides the distance to the next three exits along Interstate 405/San Diego Freeway north: Exit 47, Manchester Boulevard; Exit 48, La Tijera Boulevard; and Exit 49A, Howard Hughes Parkway. To Former California 7/Sepulveda Boulevard, follow Manchester Boulevard west toward LAX, then turn north on Sepulveda. California 7 predates Interstate 405 along this corridor, and it was eliminated in 1964 when California consolidated many of its routes. A more direct route to Old California 7 would be to stay on Interstate 405 north until the Slauson Avenue offramp (Exit 49B). Photo taken 03/25/07.
A United Airlines jet passes over the freeway as it makes its final approach into LAX. Photo taken 03/25/07.
A wide sign bridge carries signs to allocate lanes for the c-d lanes connection to Exit 46, Century Boulevard and the main lanes connection to Exit 47, Junction California 42/Manchester Boulevard. Note that this is a dual freeway, with local traffic/exits separated from through traffic here. Photos taken 03/15/08 and 02/02/08.
Northbound Interstate 405 reaches Exit 47, Junction California 42/Manchester Boulevard. A former state route that was decommissioned and removed from signage in stages through the 1990s and 2000s after completion of Interstate 105, California 42 used to start at California 1 in Los Angeles near Loyola Marymount University, then follow Manchester Avenue and Firestone Boulevard east through Los Angeles, South Gate, and Downey before ending at Junction Interstate 5/Santa Ana Freeway in Norwalk. Even though the route has been legislatively decommissioned, only a handful of signs still remain, including this freeway exit sign along Interstate 405. Photo taken 03/25/07.
The next exit along northbound Interstate 405/San Diego Freeway is Exit 48, La Tijera Boulevard (1.25 miles). This old porcelain-enamel, button-copy sign (located right after the offramp to Exit 47, Manchester Boulevard) was gone by 2007 and was not replaced. Photo taken 11/14/04.
This mileage sign provides the distance to the next three exits along Interstate 405/San Diego Freeway north: Exit 48, La Tijera Boulevard; Exit 49A, Howard Hughes Parkway; and Exit 49B, Slauson Avenue. Interstate 405 skirts the western edge of the city of Inglewood (incorporated February 14, 1908; population 112,580 as of 2000 Census). Photos taken 03/25/07 and 03/15/08.

The right lane of Interstate 405 north becomes exit only for Exit 48, La Tijera Boulevard. Photo taken 03/25/07.
This centerline view looks from the carpool (HOV) lanes north toward the offramp for Exit 48. Photo taken 03/15/08.
Northbound Interstate 405/San Diego Freeway reaches Exit 48, La Tijera Boulevard. The original porcelain enamel sign was replaced soon after we took a picture here in 2004; it was replaced with exit numbers by 2007. Photos taken 02/02/08 and 11/14/04.
The next exit from northbound Interstate 405/San Diego Freeway (Exit 49A, Howard Hughes Parkway) connects the freeway with Pepperdine University and OTIS College of Art and Design. Photos taken 03/25/07.
This mileage sign provides the distance to the next three exits along Interstate 405/San Diego Freeway north: Exit 49A, Howard Hughes Parkway; Exit 49B, Slauson Avenue; and Exit 50A, Junction California 90/Marina Freeway.

Northbound Interstate 405/San Diego Freeway reaches Exit 49B, Slauson Avenue and Sepulveda Boulevard. Slauson Avenue is an east-west city street that leads into Los Angeles en route to Pico Rivera. Sepulveda Boulevard (former California 7, the predecessor to this segment of Interstate 405) is a major north-south city street that was the original route of California 7 back when it followed the route of what is now Interstate 405. Photo taken 02/02/08.
Interstate 405 enters the city of Culver City, which is known as "The Heart of Screen Land." Culver City had a population of 38,816 as of the 2000 Census and sits at an elevation of 95 feet above sea level. Culver City was incorporated on September 7, 1917. Photo taken 02/02/08.
Quickly thereafter, northbound Interstate 405/San Diego Freeway reaches Exit 50A, Junction California 90/Marina Freeway west to Marina del Rey. California 90 was originally proposed to be a freeway parallel to Interstate 10 and Interstate 105 through South Central Los Angeles. While this freeway is still on the proposed state route legislation, it is unlikely to be constructed due to community opposition. Another segment of signed California 90 exists in Orange County between California 39 and California 91 via Imperial Highway. The proposed freeway would have connected the Imperial Highway segment with the Marina Freeway segment. Photo taken 02/02/08.
These pictures follow the double-lane transition ramp from northbound Interstate 405/San Diego Freeway to California 90/Marina Freeway west to Marina del Rey. Photos taken 03/25/07.

Use National Avenue west to Santa Monica Airport and the Museum of Flying. Photo taken 07/10/10.
Since Interstate 10/Santa Monica Freeway west connects directly to California 1/Pacific Coast Highway north, this sign reminds truckers that California 1 may not be used for through traffic northwest of California 27, except for local deliveries into the city of Malibu. The state shields in this old sign should be green, not white; it was replaced (see previous photo). Photo taken 11/14/04.
This mileage sign along northbound Interstate 405/San Diego Freeway provides the distance to Exit 53A, National Avenue; Exit 53B, Junction Interstate 10/Santa Monica Freeway; and Exit 55A, Junction California 2/Santa Monica Boulevard (Historic U.S. 66).

Northbound Interstate 405/San Diego Freeway reaches Exit 53A, National Boulevard. The 2004 photo shows a much elaborate overhead sign bridge that includes lane allocations for Exit 53B, Interstate 10/Santa Monica Freeway and a pull-through sign for Interstate 405 north. With the late 2000s reconstruction, the signs were changed so that only the action sign for exiting here remains. Photos taken 07/10/10 and 11/14/04.
Immediately thereafter, northbound Interstate 405/San Diego Freeway reaches Exit 53B, Interstate 10/Santa Monica Freeway. Interstate 10 is a major, transcontinental freeway that extends from Santa Monica east to Jacksonville, Florida, via Los Angeles, San Bernardino, Phoenix, Tucson, Las Cruces, El Paso, San Antonio, Houston, Baton Rouge, New Orleans, Biloxi-Gulfport, Mobile, and Pensacola. Interstate 10 along the Santa Monica Freeway is one of the busiest stretches of freeway in Southern California. Photos taken 07/10/10 and 11/14/04.
This pull-through sign for Interstate 405 (close-up from previous guide sign assembly) originally had a control city of Bakersfield. It was altered when Interstate 5's control city was changed to Sacramento. When the Interstate 405 expansion work was complete, the entire sign was replaced. Photo taken 11/14/04.
Follow Interstate 10 west to Santa Monica Airport. Photo taken 07/10/10.

Santa Monica Boulevard used to be part of U.S. 66; it was decommissioned in phases between 1964 and 1974. U.S. 66 was legally decommissioned in 1964, but U.S. 66 route markers did not fully disappear until the early to mid-1970s. Segments such as this one remained under state maintenance, although recently some sections of California 2 (including a portion in Santa Monica and West Los Angeles) were decommissioned and returned to local control. Photo taken 11/14/04.
