State Route 110 extends from Interstate 10 and Interstate 110 in Los Angeles, California to Glenarm Street in Pasadena, California, United States. The entire route is legally named the Pasadena Freeway. However, "Harbor Freeway" does appear on freeway signs on the segment from Interstate 10 to U.S. Route 101 in Los Angeles.
Until the early 2000's the route continued from Glenarm Street to Colorado Boulevard (in Pasadena) via Arroyo Parkway, a surface street. From US 101, the Hollywood Freeway, to Colorado Boulevard in Pasadena, State Route 110 was part of U.S. Route 66. In addition to being known as the Pasadena Freeway, the segment of State Route 110 between Interstate 5, the Golden State Freeway, in Los Angeles and Glenarm Street in Pasadena is known as the Historic Arroyo Seco Parkway, and has been declared a National Scenic Byway.
Interstate 110, the State Route's southern extension to San Pedro, is also legislatively Route 110. A short surface alignment along Gaffey Street to Ninth Street south of the end of I-110 at State Route 47 in San Pedro, was once a segment of State Route 110.
The original freeway was designed by Spencer Cortelyou and was first named the Arroyo Seco Parkway. It had no highway number designation when it first opened and originally had a speed limit of 45 miles an hour (70 km/h). Traffic originally ran in two lanes in each direction with a wide shoulder available for emergency parking. The original route of this Parkway — its 1940 appellation — ran from the Chinatown district in downtown Los Angeles to Pasadena, and was later extended to meet the Hollywood Freeway and Santa Ana Freeway. It was one of the first modern urban freeways built in the United States. The Parkway opened to traffic on December 30, 1940; a writer for the New York Times noted that it was one of the "outstanding highway improvements in the country."
The original portion of the Pasadena Freeway is considered by today's standards to be obsolete and rather dangerous. In its current six-lane configuration, there are no shoulders, although there are periodic turnouts that one can swerve into during an emergency.
Entry or exit from the freeway is a death-defying feat due to its dangerously short ramps; motorists have complained about them since the freeway opened, but the ramps have never been fixed.Cecilia Rasmussen, "Behind the Wheel: Harrowing Drive on State's Oldest Freeway — Curvy, quirky 110 carries motorists between downtown Los Angeles and Pasadena," Los Angeles Times, 6 November 2001, 2.
An excellent example is the Avenue 52 intersection in Highland Park. At this point the freeway is depressed and Avenue 52 passes over it. There is one on-ramp and one off-ramp in each direction, each perhaps 100 feet (30 meters) in length. At the bottom of the on-ramp there is actually a limit line and a stop sign. Freeway users must stop at the line, wait for an opening in traffic, and then accelerate from a complete stop directly into traffic moving at 55 mph — there is no acceleration lane.
Exiting the freeway entails pulling onto the off-ramp while still at speed and skidding to a stop. While the freeway is posted for 55 mph (90 km/h), most drivers regard the speed limit as nothing more than guidelines.
When traveling from Los Angeles into South Pasadena, there is a set of sharp, sweeping turns required to keep the freeway within the bounds of the canyon. Since the original design envisioned a much slower traffic flow, these turns are not banked. The speed through them is reduced, but driving this freeway for the first time can be, even for an experienced driver, a hair-raising experience. Despite all this, the freeway is still heavily used by drivers, as it remains the most direct route between Los Angeles and Pasadena for automobiles.
Four medium-sized tunnels (called the "Figueroa Street Tunnels") run under and through the hills of Elysian Park. In the northward direction (toward Pasadena), stairways and bus pads can still be seen to the left before the tunnels. These remnants date from the days when the Arroyo Seco Parkway was first opened, and are no longer in use.
The Pasadena Freeway runs through heavily working-class Latino neighborhoods such as Lincoln Heights and Highland Park, as well as upper-middle-class white populated portions of Pasadena and South Pasadena (these generalizations about ethnicity are drawn from U.S. Census data).
Tucked within the southwest loop of the intersection with Interstate 10 is the Central Los Angeles office of the California Highway Patrol. It was heavily photographed for the 1970s U.S. television program CHiPs, as it was depicted as the home office of its main characters, Officers Jon Baker and Frank Poncherello. It does not have direct access to or from either freeway, though.
During the 1992 Los Angeles riots, a white truck driver named Reginald Denny was pulled from his truck and beaten on an intersection, Florence Avenue and Normandie Street, about a mile (2 km) west from the 110 Freeway. The incident was broadcast live via news helicopter.
The Pasadena Freeway can be seen in the introduction of the 1971 Steven Spielberg film, Duel. Dennis Weaver's character drives through several tunnels before entering the Interstate 5 interchange (which leads to Sacramento and beyond).
Prior to Ankrom's work, the only signage directing motorists to the 5 North off-ramp came at a quarter-mile before the exit, thus forcing many to merge across multiple lanes in a very short distance. The unofficial modifications remain on the sign to this day, after having been inspected by CalTrans to ensure it would not fall off onto the road below. CalTrans is gradually upgrading all California freeway signs to a newer, more reflective form; when this happens on the 110, Ankrom's work will be lost, but the new sign will include "5 North" icons.
Ankrom was never charged, despite statements from officials that his actions were illegal.
