Interstate 405 - North - Los Angeles County #1

Interstate 405 Guide

Interstate 405/San Diego Freeway north
Interstate 405/San Diego Freeway leaves Orange County and Seal Beach and enters Los Angeles County and the city of Long Beach. Long Beach was incorporated on February 10, 1888, then disincorporated July 24, 1896, and it reincorporated on December 13, 1897. The city of Long Beach ("Many Unique Neighborhoods, One Great City") is home to the busy Port of Long Beach, Queen Mary, Aquarium of the Pacific, and California State University at Long Beach (CSULB). The city consists of 50 square miles (excluding water acreage) and had a population of 461,522 as of the 2000 Census. Photos taken 07/13/09 and 11/25/04.
Between the California 22 and Interstate 605 interchanges, Interstate 405 turns due north, then turns northwest until Exit 26A (Woodruff Avenue). This sign again notes Interstate 405 is the San Diego Freeway, and it is the second one seen after the one after the California 22/Garden Grove Freeway merge. This sign is posted after the county line, which also serves as the boundary between Caltrans Districts 12 (Orange County) and 7 (Los Angeles/Ventura County). Photo taken 02/02/08.
The next exit along Interstate 405/San Diego Freeway is Exit 25, Palo Verde Avenue (0.75 mile). Photo taken 07/13/09.
Use Palo Verde Avenue south to the California State University at Long Beach. Photo taken 02/02/08.

The right lane of Interstate 405/San Diego Freeway connects to Exit 29A, Cherry Avenue south to Signal Hill. Photo taken 07/13/09.
Northbound Interstate 405 meets Exit 29A, Cherry Avenue South, which leads into Signal Hill, a community nestled between Lakewood and Long Beach. Photo taken 06/15/03.
The next three exits along Interstate 405 north are Exit 29B, Cherry Avenue north (reflective sign for exit only has been in place since around 2004); Exit 29C, Orange Avenue; and Exit 30A, Atlantic Avenue (former California 15). Photo taken 07/13/09.
Traffic connecting to Exit 29B, Cherry Avenue north moves onto a collector-distributor lane. Next to the gore point exit for Exit 29B, another upcoming exits mileage sign is posted in the median along this busy stretch of Interstate 405. Photo taken 11/25/04.
This view looks at the offramp signage for Exit 29B (Cherry Avenue north) looking at the collector-distributor lanes as seen from the main lanes. The signs were replaced sometime between 2005 and 2008, with the pull-through sign changing from "Freeway" to "Interstate 405 North." Photos taken 02/02/08, 03/25/07, and 09/25/05.
Northbound Interstate 405 meets Exit 29C, Orange Avenue. The next exit is Exit 30A, Atlantic Avenue (see the southbound notes for information about the significance of Atlantic Avenue). Photo taken 07/13/09.
This mileage sign along northbound Interstate 405/San Diego Freeway provides the distance to the next four exits: Exit 30A, Atlantic Avenue (Former California 15); Exit 30B, Wardlow Road and Long Beach Boulevard; Exit 32A, Junction Interstate 710/Long Beach Freeway north to Pasadena; and Exit 32B, Junction Interstate 710/Long Beach Freeway south to downtown Long Beach and the Port of Long Beach. Photo taken 07/13/09.
As the collector-distributor lanes that served Exits 29A-B-C return to the mainline freeway, merging traffic sees this Interstate 405 north reassurance shield. The offramp seen to the right in this photo leads to Exit 29C. Photo taken 02/02/08.
At this point, Interstate 405 briefly leaves Long Beach and enters the city of Signal Hill. This city, which is entirely surrounded by the city of Long Beach and thus is considered an "enclave," was incorporated on April 22, 1924, had a population of 9,333 as of the 2000 Census. Photo taken 02/02/08.
Northbound Interstate 405/San Diego Freeway reaches Exit 30A, Atlantic Avenue (Former California 15). The offramp here once again connects to a collector-distributor lane arrangement, meaning that through traffic may also exit here and still return to the freeway. Photo taken 11/25/04.
Immediately after exiting onto the collector-distributor lanes, traffic may exit left to get back onto Interstate 405's main lanes or exit right to the ramps for Atlantic Avenue north and south. Photo taken 03/25/07.
Back on the mainline, this mileage sign along northbound Interstate 405/San Diego Freeway provides the distance to four of the next five exits: Exit 30B, Wardlow Road and Long Beach Boulevard; Exit 32A, Junction Interstate 710/Long Beach Freeway north to Pasadena; Exit 32B, Junction Interstate 710/Long Beach Freeway south to downtown Long Beach and the Port of Long Beach; (Exit 32C, Santa Fe Avenue;) and Exit 33A, Junction California 47/Alameda Street. Photo taken 11/25/04.
Looking at the collector-distributor lanes, the local lanes divide, with the first ramp connecting to Atlantic Avenue north, and the second ramp linking to Atlantic Avenue south. A north-south arterial street, Atlantic Avenue has a place as an historic route of significance for the greater Los Angeles Area. At one time, Atlantic Avenue was a state route (California 15), and it served as the endpoints for two former U.S. routes until 1964. The intersection of Atlantic Avenue and California 1/Pacific Coast Highway in Long Beach was the southwestern termini for both transcontinental east-west U.S. 6 and north-south U.S. 91. Both were paired with decommissioned Alternate U.S. 101 along Pacific Coast Highway (U.S. 6 along southbound Alternate U.S. 101 and U.S. 91 along northbound Alternate U.S. 101) as Alternate U.S. 101 approached this intersection. Photos taken 09/25/05 and 04/21/07.
Northbound Interstate 405 meets Exit 30B, Long Beach Boulevard. Note the use of collector-distributor lanes for the Atlantic Avenue south exit. Photos taken 09/25/05 and 04/21/07.
The collector-distributor lanes next meet the offramp to Long Beach Boulevard, and then through traffic may merge back onto Interstate 405's northbound main lanes. Photos taken 02/02/08 and 03/25/07.
This mileage sign along northbound Interstate 405/San Diego Freeway provides the distance to the next four exits: Exit 32A, Junction Interstate 710/Long Beach Freeway north to Pasadena; Exit 32B, Junction Interstate 710/Long Beach Freeway south to downtown Long Beach and the Port of Long Beach; Exit 32C, Santa Fe Avenue; and Exit 33A, Junction California 47/Alameda Street The Santa Fe Avenue offramp (Exit 32C) is joined with the southbound Interstate 710 transition ramp (Exit 32B). Photo taken 06/15/03.
Interstate 405 keeps its left five lanes for northbound traffic, while the two right lanes lead to Interstate 710 (Exits 32A-B). These signs have faded a bit over the course of four years. Photos taken 07/13/09 and 11/25/04.
Northbound Interstate 405/San Diego Freeway reaches Exit 32A, Junction Interstate 710/Long Beach Freeway north. Although signed to Pasadena, Interstate 710 remains unconstructed between Interstate 10 and Interstate 210, thus negating direct access to its intended northern destination. Photos taken 07/13/09 and 11/25/04.
The next offramp connects Interstate 405/San Diego Freeway to a collector-distributor lane that leads to Exit 32B, Junction Interstate 710/Long Beach Freeway south and Exit 32C, Santa Fe Avenue. Photo taken 11/14/04.
Northbound Interstate 405/San Diego Freeway reaches Exit 32B, Interstate 710/Long Beach Freeway south to downtown Long Beach and Exit 32C, Santa Fe Avenue. Through traffic may use this exit and return to Interstate 405 north. Interstate 710 south leads to the ports of Long Beach and Los Angeles, as well as downtown Long Beach, the Queen Mary, cruise ship terminal, and aquarium. Photo taken 07/13/09.
Now on the collector-distributor lanes, an overhead sign provides the lane allocation for the connection to Interstate 710 south (Exit 32B). Stay left to return to northbound Interstate 405 or to depart the freeway at Exit 32C, Santa Fe Avenue. These reflective signs have been in place since at least 2004. Photos taken 07/13/09 and 11/25/04.
Returning to the main lanes, the next exit from Interstate 405 north will be Exit 33A, Junction California 47/Alameda Street. Visible in the collector-distributor lanes is the approaching offramp to Exit 32C, Santa Fe Avenue. Photo taken 11/25/04.
Looking at the collector-distributor lanes, northbound Interstate 405/San Diego Freeway reaches Exit 32C, Santa Fe Avenue. Through traffic may return to Interstate 405 north. Incoming traffic from Interstate 710 also uses the c-d lanes to return to the Interstate 405 main lanes. Photo taken 11/25/04.
The next three exits from Interstate 405 north are: Exit 33A, Junction California 47/Alameda Street; Exit 33B, Wilmington Avenue; and Exit 34, Carson Street and Avalon Boulevard south. Photo taken 11/25/04.
The next five exits along Interstate 405 north serve the city of Carson: Exit 33A, Junction California 47/Alameda Street; Exit 33B, Wilmington Avenue; Exit 34, Carson Street and Avalon Boulevard south; Exit 35, Avalon Boulevard north; and Exit 36, Main Street. Interstate 405 leaves Long Beach and enters the city of Carson ("Future Unlimited," population 89,730 as of the 2000 Census, and incorporated on February 20, 1968). Photo taken 03/25/07.
California 47 follows Alameda Street along the Alameda Corridor, which is an approximately 20-mile long freight rail corridor owned by the Alameda Corridor Transportation Authority and part of Congressional High Priority Corridor 22. As part of the project to upgrade the freight rail corridor by removing at-grade railroad crossings and creating the Mid-Corridor Trench (a ten-mile section of railroad with triple track below grade opened on April 15, 2002), nearby Alameda Street was upgraded to expressway characteristics between Henry Ford Avenue and California 91. This segment of expressway was designated and signed as part of California 47 in 2002, but it is not (as of August 2010) state maintained. Currently, the signs for Alameda Street at the Interstate 405 and California 91 interchanges do not reference the California 47 designation. On Alameda Street itself, reassurance markers for California 47 are posted as far north as the California 91 freeway. Photo taken 03/25/07.
Northbound Interstate 405/San Diego Freeway reaches Exit 33A, Junction California 47/Alameda Street in the city of Carson. The second exit is Exit 33B, Wilmington Avenue. Photo taken 03/25/07.
The right lane along Interstate 405/San Diego Freeway north becomes exit only for Exit 33B, Wilmington Avenue. Photo taken 11/25/04.
This mileage sign provides the distance to the next three exits along Interstate 405 north: Exit 33B, Wilmington Avenue; Exit 34, Carson Street and Avalon Boulevard south; and Exit 35, Avalon Boulevard north. Photo taken 03/25/07.
Northbound Interstate 405/San Diego Freeway reaches Exit 33B, Wilmington Avenue. A construction project in 2007 modified this offramp to an exit only configuration. When this happened, the overhead guide sign was replaced with a new exit number sign. Photos taken 03/15/08 and 11/25/04.
This mileage sign provides the distance to the next three exits along Interstate 405 north: Exit 34, Carson Street and Avalon Boulevard south; Exit 35, Avalon Boulevard north; and Exit 36, Main Street.

The next two exits along Interstate 405/San Diego Freeway north are Exit 36, Main Street and Exit 37, Junction Interstate 110/Harbor Freeway. Main Street is the final exit to serve the city of Carson. The Harbor Freeway, which was constructed as U.S. 6 and California 11 in the late 1950s and early 1960s, became designated exclusively as California 11 after U.S. 6 was decommissioned through much of California in 1964. In 1981, signs for California 11 were replaced with signs for Interstate 110 along the Harbor Freeway south of Interstate 10 (north of there, California 11 became California 110). Photos taken 03/25/07 and 11/25/04.
Northbound Interstate 405/San Diego Freeway reaches Exit 36, Main Street. Stay left to continue north on Interstate 405 or merge right to connect to Interstate 110 north/south. Photo taken 11/14/04.
Immediately thereafter, northbound Interstate 405/San Diego Freeway meets Exit 37, Junction Interstate 110/Harbor Freeway. The right two lanes connect to Interstate 110 north/south, while the left four lanes (including the carpool lane) continue north on Interstate 405. Interstate 110 travels north to downtown Los Angeles as the Harbor Freeway, then changes into the Arroyo Seco Parkway (Pasadena Freeway) upon passing through the Four-Level Interchange (Junction U.S. 101 and California 110). California 110 travels northeast from the Four-Level, ending near downtown Pasadena after passing through that historic corridor. To the south, Interstate 110 connects to California 47 east to the commercial Ports of Los Angeles and Long Beach and connects to Gaffey Street en route to San Pedro, a community of Los Angeles. A busy north-south freeway, Interstate 110 includes the Transitway for buses and high occupancy vehicles leading north toward downtown Los Angeles. Photo taken 11/14/04.
Looking at the transition ramp from Interstate 405/San Diego Freeway north to Interstate 110/Harbor Freeway, the right lane allows trucks to merge onto the right side of Interstate 110 north. The middle lanes connect to Interstate 110 north on the left side. The left lane of the transition ramp will connect onto Interstate 110 south. Photos taken 11/14/04 and 11/25/04.

Despite the numerical designation, at no time did U.S. 91 extend this far west. What is now California 91 was designated as California 14 until 1964, when many state routes and U.S. routes were renumbered in California. Historically, U.S. 91 deviated from California 91 in Anaheim and took Center Street and Carson Street west to Lakewood Boulevard, Lakewood Boulevard south to former U.S. 101A (today's California 1/Pacific Coast Highway), and California 1/PCH northwest to Atlantic Avenue. At the PCH/Atlantic Avenue traffic signal, U.S. 91 arrived at its southern terminus, and U.S. 6 began its northerly journey toward downtown (and ultimately its easterly journey toward Massachusetts). U.S. 6 and U.S. 91 would meet again in Central Utah. Photo taken 03/25/07.
Use Exit 40 to California 91 west to Redondo Beach and Hermosa Beach or east to Torrance and Gardena. The exit also connects to Prairie Avenue north to Lawndale, El Camino Village, and Hawthorne and south into western Torrance. Photos taken 03/25/07.
Northbound Interstate 405/San Diego Freeway reaches Exit 40, Junction California 91/Artesia Boulevard west to Redondo Beach and Hermosa Beach or east to Torrance and Gardena. The exit also connects to Prairie Avenue north. Note that in the 2007 picture, the California 91 route marker overlay likely covers up an original California 14 shield. The replacement sign (from 2008) incorrectly shows the exit number as Exit 40A; it should be just Exit 40. The next exit is Exit 42A, Junction California 107/Hawthorne Boulevard. Photos taken 03/15/08 and 03/25/07.
