Northbound Gaffey Street (former California 110) approaches Fifth Street in San Pedro. California 110 used to be signed along Gaffey Street from Ninth Street north to the beginning of the Harbor Freeway. Photo taken 09/29/07.
Gaffey Street passes by a McDonald's at Third Street. Photo taken 09/29/07.
Northbound California 110/Gaffey Street meets at First Street in San Pedro. In a few blocks, Gaffey Street will meet the freeway entrance to the Harbor Freeway. Photo taken 09/29/07.
Interstate 110/Harbor Freeway begins its northerly journey upon departing Gaffey Street. The right two lanes of Gaffey Street become northbound Harbor Freeway, with a connection to California 47/Vincent Thomas Bridge available in the far right lane. While some maps show Gaffey Street between 9th Street and Interstate 110 as California 110, it is not currently part of the state highway system. A pedestrian overcrossing doubles as an arch wishing visitors to "come back to San Pedro soon." San Pedro is not its own city; it is actually a community within the city of Los Angeles. Photo taken 09/28/08.
Interstate 110/Harbor Freeway (Historic California 11) north
A vandalized freeway entrance sign is posted without a companion shield assembly for either Interstate 110 or California 47. The first exit along Interstate 110 north is Exit 1A, Junction California 47/Seaside Freeway north (east) to the Ports of Los Angeles and Long Beach. Photo taken 09/28/08.
The initial freeway only carries two northbound lanes. That will change north of the California 47 split, which is just a short distance ahead. Interstate 110 largely remains within the city of Los Angeles from its inception north toward downtown, although it deviates into adjacent communities and cities from time to time. Los Angeles, which is also known also as "The City of Angels," represents the second largest metropolitan area within the United States. Commonly referred to as L.A., Los Angeles is also the largest city in California and has a population of 3,694,820 people as of the 2000 Census. The city continues to grow. Los Angeles is a chartered city with a mayor-council form of government, consists of 498.3 square miles (including 29.2 square miles of water), and was incorporated on April 4, 1850. Photo taken 09/28/08.
Northbound Interstate 110/Harbor Freeway and California 47/Seaside Freeway split at Exit 1A immediately thereafter. California 47 travels east via the Vincent Thomas Bridge to Terminal Island and the Ports of Los Angeles and Long Beach. From Terminal Island, California 47 turns north to join the Alameda Corridor, which is a major north-south rail and truck route to help facilitate carrying cargo from the ports north to the major shipping and rail facilities near downtown Los Angeles. Photo taken 09/28/08.
The first reassurance route marker for Interstate 110 is posted shortly after the California 47 interchange. Prior to 2004, this shield was button-copy and neutered (without the state name), mostly likely surplus from an overhead sign retrofit. This sign has since been replaced by a more typical Interstate 110 route marker shield. At this point, traffic from California 47 south (west) merges onto Interstate 110 north. Photos taken 07/13/09 and 03/31/03.
The next exit along Interstate 110 north is Exit 1B, Channel Street and John S. Gibson Boulevard. Photo taken 02/02/08.

A towering tangle of ramps stack above Interstate 110/Harbor Freeway at the Interstate 105/Glenn Anderson Freeway interchange. In addition to providing connectors between all directions of both freeways, the Transitway lanes have direct connectors to the Interstate 105 carpool lanes, thus adding a new layer on top of the stack interchange. Photo taken 07/13/09.
The interchange between Interstate 110/Harbor Freeway and Interstate 105/Glenn Anderson Freeway is named in honor of Judge Harry Pregerson. Photo taken 12/25/04.

Looking at the impossibly high transition ramps of the 105-110 interchange, this view shows the transition ramp from the high occupancy vehicle lanes on westbound Interstate 105 to northbound Interstate 110. Photo taken 02/15/04.
Now descending from such heights, the high occupancy vehicle lanes from westbound Interstate 105 enter northbound Interstate 110 on the left so as to merge with the Interstate 110 high occupancy vehicles. The skyline of downtown Los Angeles is visible in the distance. Photo taken 02/15/04.
This picture provides another view of the high occupancy (carpool) vehicle transition lane as it reaches the level of Interstate 110. Photo taken 02/15/04.
Back in the main lanes and leaving the Interstate 105 interchange, this mileage sign along northbound Interstate 110/Harbor Freeway provides the distance to the next three exits: Exit 16, Junction Former California 42/Manchester Avenue; Exit 17, Florence Avenue; and Exit 18A, Gage Avenue. Photo taken 09/25/05.
The right two lanes will connect to Exit 16, Manchester Avenue. Until the late 1990s, Manchester Avenue was signed as California 42, even though it was removed from the legislative state route system many years prior. However, when Interstate 105 was completed, California 42 was no longer needed as a state highway, and it was turned back to the cities it passed through. Remnants of the old designation are still clearly visible on this sign located along northbound Interstate 110/Harbor Freeway approaching Exit 16, Manchester Avenue. Photo taken 07/13/09.
The Transitway (high occupancy vehicle lanes) approaches a bus ramp prior to the offramp to Manchester Avenue. The high occupancy vehicles become separated from the main lanes of the freeway, with connections back to the mainline between Exits 20-21. Photos taken 09/25/05 and 02/15/04.

Over in the Transitway/HOV lanes, an overhead sign separates through traffic from buses in anticipation of the bus stop at Slauson Avenue. Photo taken 09/25/05.
Northbound Interstate 110/Harbor Freeway reaches Exit 18B, Slauson Avenue. Slauson Avenue gained notoriety in the early 1990s when it was mentioned in Dr. Dre's song "Let Me Ride" from 1992. Proceeding north, Interstate 110 passes through the heart of South Central Los Angeles (still within the city of Los Angeles). Photo taken 07/13/09.
This Interstate 110 north reassurance shield is posted along the northbound Harbor Freeway after the onramp from Slauson Avenue and prior to Exit 19, Vernon Avenue. The downtown Los Angeles skyline comes into view in the distance ahead. Photo taken 07/13/09.

As the Transitway (high-occupancy, grade-separated lanes) comes to an end, this mileage sign along Interstate 110/Harbor Freeway north provides the distance to Exit 20B, 37th Street and Exposition Boulevard; Exit 20C, Adams Boulevard, and Exit 21, Junction Interstate 10/Santa Monica Freeway. Photos taken 09/25/05 and 02/15/04.
Motorists along the high occupancy vehicle lanes have an array of their own options on the separated lanes. The left lane provides carpool only access to 39th Street, while the middle lane heads into downtown via Adams Boulevard and Figueroa Street. All through traffic should merge to the right lane to continue north on Interstate 110, which downgrades to California 110 upon crossing the Interstate 10 interchange (Exit 21). Photos taken 09/25/05 and 02/15/04.
At the same time, through traffic leaves the segregated high occupancy vehicle lanes and merges onto northbound Interstate 110. The high occupancy vehicle lanes continue north, but they do not rejoin the freeway; instead, they head into downtown Los Angeles. There are plans to extend the high occupancy lanes further along Interstate 110 and California 110, but that would be a costly endeavor. Photos taken 09/25/05 and 02/15/04.

Northbound Interstate 110/Harbor Freeway approaches Exit 21, Junction Interstate 10. The far right lane is for eastbound and the second lane from the right is for westbound. Photo taken 07/13/09.
This mileage sign along northbound Interstate 110/Harbor Freeway provides the distance to the next four exits: Exit 21, Junction Interstate 10/Santa Monica Freeway; Exit 22, 6th Street and 9th Street (called the "Downtown Exit" on this sign), and Exits 23A-B, 4th and 3rd Streets. Exit 21 serves Interstate 110; Exits 22 and 23A-B serve California 110. Photo taken 07/13/09.
The next exit along Interstate 110/Harbor Freeway north is Exit 21, Junction Interstate 10/Santa Monica Freeway. Note the green overlay panels that feature the California 110 shields; they used to be California 11 shields. Photos taken 07/13/09 and 12/25/04.
These small reflective signs are mounted on a bridge over northbound Interstate 110/Harbor Freeway; they are placed here to remind motorists of the lane allocation on the approach to Exit 21, Junction Interstate 10/Santa Monica Freeway. Photo taken 07/13/09.
Interstate 110 ends as the two right lanes exit onto Interstate 10; California 110 continues north along the Harbor Freeway into downtown Los Angeles. The second largest city in the country, Los Angeles is the hub of Southern California and a major media market. Most movies made in the United States come from Hollywood, a community of Los Angeles. California 110 now passes through what is arguably one of the most recognizable skylines in the country, due to its presence in many movies. Photos taken 07/13/09 and 12/25/04.
This view of the signage for Interstate 10 east and west is taken from the transition ramp as seen from northbound Interstate 110/Harbor Freeway. Use Exit 21 to Pico Boulevard as well as both directions of Interstate 10. Photo taken 08/15/03.
California 110/Harbor Freeway (Historic U.S. 6 and California 11) north
Northbound California 110/Harbor Freeway approaches Exit 22, 6th Street and 9th Street. Photos taken 09/25/05 and 12/25/04.
Exit 22 provides access into downtown Los Angeles via 6th Street and 9th Street, meeting Figueroa Boulevard and South Grand Avenue. Both 6th Avenue and 9th Avenue are one-way eastbound near California 110. Use this exit to James M. Wood Boulevard and Loyola Law School.

For Figueroa Street (Old U.S. 6 and California 11), use Exit 22. The offramp to Exit 22 actually connects to a collector-distributor lane arrangement as we enter downtown Los Angeles. Photo taken 11/08/08.
Use Exit 22 to Fifth Street and Sixth Street (as part of the local/express configuration of the Harbor Freeway through downtown Los Angeles). Photos taken 08/26/07 and 11/08/08.
Northbound California 110/Harbor Freeway splits into a local/express configuration at this point. Stay right for local access to Exit 22, Sixth Street and Ninth Street and Exits 23A-B-C, Sixth Street, Fourth Street, and Third Street. Stay left for California 110 north to Pasadena (note that a slip ramp will allow access to Exits 23B-C from the express lanes). Photos taken 04/21/07 and 11/08/08.
The skyline of downtown Los Angeles dominates the northbound view along California 110. The right two lanes become the local lanes that will connect to Ninth Street (Exit 22), Sixth Street (Exit 23A), Fourth Street (Exit 23B), and Third Street (Exit 23C) before rejoining the California 110 express lanes prior to the Four-Level Interchange with U.S. 101. Photos taken 11/08/08 and 01/14/07.
Northbound California 110/Harbor Freeway reaches Exit 22, Ninth Street to the southern part of downtown Los Angeles, including the Staples Center (home of the NBA L.A. Lakers and Clippers and the NHL L.A. Kings), Los Angeles Convention Center, Nokia Theater, and Grammy Museum. Use Ninth Street southeast to the Los Angeles Fashion District (sometimes called the Garment District). These views look from the main lanes and the c-d lanes. Photos taken 11/08/08, 08/26/07, 04/21/07, and 01/14/07.
The gore point sign for Exit 22 is the only one to show the correct exit number (as of 2008), as the advance signs showed this exit with its original exit number of 22A (from the exit numbering experiment from the early 1970s). No gore point signage was in place at all a year prior (in 2007). Photos taken 11/08/08 and 08/26/07.
v
Signed here as Exit 22B (from the 1970s experimental exit numbering program), the express lanes of northbound California 110/Harbor Freeway has a slip ramp to the local lanes for access to Exit 23A, Sixth Street; Exit 23B, Fourth Street; and Exit 23C, Third Street. (Third picture is from the c-d/local lanes.) Photos taken 04/21/07 and 08/26/07.
The next exit along California 110 north is Exit 23A, Sixth Street (accessible only from the local lanes). Note the 2005 picture, which shows an unusually empty Harbor Freeway. Normally this freeway is congested. To Interstate 5/Golden State Freeway north, follow California 110/Arroyo Seco Parkway north. (Third and fourth picture taken from local lanes.) Photo taken 09/25/05, 04/21/07, 08/26/07, and 11/08/08.
This mileage sign along California 110 north (in the express lanes) provides the distance to the next three exits available from the express lanes (and thus ignoring Exit 23A, Sixth Street; Exit 23B, Fourth Street; and Exit 23C, Third Street that are accessible only from the local lanes): Exit 24A, Junction U.S. 101/Hollywood Freeway north to Ventura and U.S. 101/Santa Ana Freeway south to Interstate 10/San Bernardino Freeway east (Four-Level Interchange); Exit 24B, Hill Street to Dodger Stadium; and Exit 25, Solano Avenue and Academy Road. Photo taken 12/25/04.
The next exit along California 110/Harbor Freeway north is Exit 23A, Sixth Street. The right lane of the local lanes becomes exit only for Exit 23A. Meanwhile, the overhead guide sign in the express lanes advises of the major interchange between California 110 and U.S. 101. Consistent with older Caltrans standards, this porcelain enamel sign shows the Four-Level interchange as being U.S. 101 north to Hollywood and Interstate 5 south to Santa Ana. Given recent changes to signs on U.S. 101 itself, it is likely that sign will be changed eventually to say U.S. 101 north to Ventura and U.S. 101 south to Interstate 5 south to Santa Ana, Interstate 10 east to San Bernardino, and California 60 east to Pomona. Photos taken 04/21/07 and 11/08/08.
Northbound California 110 reaches Exit 23A, Sixth Street (from the local lanes only). The middle lane becomes exits only for Exit 23B, Fourth Street and Exit 23C, Third Street. In the local lanes, stay left to merge back onto California 110/Harbor Freeway (which transitions directly onto the Arroyo Seco Parkway after the Four-Level Interchange) north. Photos taken 04/21/07 and 11/08/08.
Upon exiting from the Harbor Freeway, the offramp to Exit 23A becomes eastbound Sixth Street. The first traffic signal ahead is with north-south Figueroa Street, which is the old alignment of U.S. 6 and California 11. Sixth Street travels southeast to Pershing Square, turning east at Alameda Street. From there, Sixth Street crosses the Los Angeles River and transitions into Whittier Boulevard. Photos taken 08/26/07.
California 110 passes under Sixth Street (as seen from the main/express lanes). Photo taken 04/21/07.
To Third Street west and Flower Street south, use Exit 23C (second right). Photo taken 11/08/08.
Still on the local (collector-distributor) lanes, northbound California 110 meets Exit 23B, Fourth Street. This is a major offramp into downtown Los Angeles. The next exit along northbound local lanes is Exit 23C, Third Street. Photos taken 11/08/08 and 08/26/07.
Immediately thereafter, northbound California 110 reaches Exit 23C, Third Street west and Flower Street south. The right lane departs the freeway here, while the left lane will merge back onto the main lanes of California 110 north. Photos taken 07/13/09 and 11/08/08.
Now on the offramp to Exit 23C, the left lane will connect to Third Street west, while the right lane will connect to Flower Street south. Photo taken 08/26/07.
Traffic from the local and express lanes merge back together again. The next exit along Interstate 110/Harbor Freeway north is Exit 24A, Junction U.S. 101/Hollywood Freeway north and U.S. 101/Santa Ana Freeway south. U.S. 101/Hollywood Freeway travels northwest toward Hollywood and the San Fernando Valley; at the Hollywood Split Interchange, U.S. 101 curves west toward Ventura and Santa Barbara. To the southeast, U.S. 101/Santa Ana Freeway passes through the Downtown Slot to meet Interstate 10/San Bernardino Freeway east and California 60/Pomona Freeway east before merging with Interstate 5/Santa Ana Freeway. Photos taken 07/10/10 and 05/08/10.
This pictures show the button copy sign previously installed at that location. The sign was altered in 2002 by local artist Richard Ankrom, who had gotten lost one too many times trying to get from northbound California 110 to northbound Interstate 5. So over the course of weeks, he obtained the specifications for an Interstate shield, and once it was complete to Caltrans standards for button copy, non-reflective signage (prior to the new reflective signage standard), he installed the "North Interstate 5" shield on the green area to the left of the Northbound California 110 pull-through shield. For more on Richard Ankrom and his project, visit The L.A. Weekly: A Considerable Town - Guerrilla Public Service: The Man Who Would Be Caltrans (May 10-16, 2002). In 2009, this sign was completely removed, and the sign shown in the above photobox was installed in its place. Photos taken 04/21/07 and 11/08/08.
Prior to the Four-Level Interchange, a regulatory sign advises that trucks are prohibited from California 110/Arroyo Seco Parkway. Trucks should connect to U.S. 101 north/south. Photo taken 12/25/04.
The left lanes carry California 110 traffic, while the right lanes default to north/south U.S. 101. Southbound U.S. 101/Santa Ana Freeway leads to a connection with Interstate 5 and Interstate 10. Northbound U.S. 101/Hollywood Freeway leads north to a connection with California 170 and California 134/Ventura Freeway. No trucks are permitted on northbound California 110; California 110 continues north as the Pasadena Freeway and the Harbor Freeway comes to its northern terminus here at the Four-Level Interchange. The close-up photos provide details of the shields. Since some of these signs are already being replaced, we try to get as much detail of the older sign as we can. Photos taken 07/10/10 and 11/08/08.
Northbound California 110/Harbor Freeway meets Exit 24A, Junction U.S. 101/Santa Ana Freeway southeast and U.S. 101/Hollywood Freeway northwest. Despite the signage here, California 110 does NOT intersect Interstate 5 or Interstate 10 at this intersection! In reality, the right-hand ramp actually connects to southbound U.S. 101, which then leads to both directions of Interstate 10 and southbound Interstate 5. The way this is currently labeled can be very confusing, since it seems like you're intersecting the same road several times. Eventually we suspect this sign will match the 2009 replacements signs to read something like, "South U.S. 101 to East Interstate 10, East California 60, and South Interstate 5." Photos taken 07/10/10 and 11/08/08.
Now on the transition ramp from California 110/Harbor Freeway to U.S. 101, the left lane connects to U.S. 101 north to Hollywood and Ventura and the right lane connects to U.S. 101 south to Santa Ana. The Four-Level Interchange, which is the intersection of the Santa Ana, Hollywood, Harbor, and Pasadena Freeways (or the intersection of the 101 and 110 freeways), is ahead on northbound California 110. Northbound California 110 shifts from the Harbor Freeway onto the Pasadena Freeway upon passing under this interchange, and it also becomes the historic route of the Figueroa Street Tunnels and Arroyo Seco Parkway (old U.S. 66). Photos taken 04/21/07 and 12/25/04.
These views show the transition from California 110/Harbor Freeway north to U.S. 101/Hollywood Freeway northwest to Hollywood and Ventura. This connecting ramp is the bottom level of the stack interchange. Photos taken 04/21/07 and 12/25/04.
For those transitioning from California 110 north to U.S. 101 south, a slip ramp to Temple Street is provided before merging onto U.S. 101/Santa Ana Freeway south. Opened in 1954, the Four-Level Interchange is known as the first symmetrical stack of its kind, and similar interchanges have been built elsewhere throughout the country. Photo taken 07/13/09.
Back on the mainline, this series of photos follows California 110 north through the Four-Level Interchange. As we pass through the interchange, California 110 leaves the Harbor Freeway and shifts directly onto the Pasadena Freeway (Historic Arroyo Seco Parkway). California 110 takes the second of four levels, with U.S. 101 passing overhead on the top level and some flyover ramps on the third level. An older postmile used to have Route 11 on it, but a zero was added to it so the paddle would be consistent with the route numbering. Historically, other U.S. routes besides U.S. 101 used to pass through this interchange. Prior to 1964, U.S. 6 followed today's California 110 through the interchange, while U.S. 60-70 may have briefly began their eastbound journey from this interchange (this is based on a 1950-60s era Rand McNally road map, although both routes are generally accepted to have begun at the Interstate 5/Interstate 10 interchange east of here). U.S. 66 entered the Four-Level Interchange along with U.S. 101 from the northwest, then shifted onto California 11/Arroyo Seco Parkway north. Theory holds that if the U.S. routes were not eliminated in 1964, U.S. 6 may have been rerouted/transferred onto a brief overlap with U.S. 101 north (along with U.S. 66), then proceed along today's California 170/Hollywood Freeway to join U.S. 99 (today's Interstate 5) near Burbank. Photos taken 07/10/10, 11/08/08, 04/30/06, and 09/25/05.
