Car Accidents in Pasadena: Interchanges, Old Pasadena and Claims

Pasadena is where three very different freeways meet. The I-210 (Foothill Freeway) and SR-134 (Ventura Freeway) interchange sits just north of downtown, and the historic SR-110 Arroyo Seco Parkway—the oldest freeway in the West, with short ramps and no shoulders—ends at the city’s southern edge. Add Colorado Boulevard, Lake Avenue, Fair Oaks Avenue and Arroyo Parkway and you have a network that mixes high-speed through traffic with a dense, walkable core.

Old Pasadena, the Playhouse District, Caltech and Pasadena City College draw pedestrians and cyclists throughout the day, and the Rose Bowl adds event surges for UCLA football, concerts, the flea market and the Rose Parade and Rose Bowl Game each January.

Who writes the collision report in Pasadena

The Pasadena Police Department handles collisions on city streets. The California Highway Patrol handles I-210, SR-134 and SR-110 within the city. Collisions on the Caltech campus may involve Caltech Security as well as Pasadena PD. Rose Bowl event traffic is managed under city traffic plans with officers directing traffic at major intersections.

Where Pasadena collisions happen

I-210 / SR-134 interchange and the I-710 stub

Weaving between the 210, 134 and the short 710 stub near California Boulevard and Del Mar is a frequent site of sideswipe and merge collisions.

Arroyo Seco Parkway (SR-110)

Designed in the 1930s, the Parkway has very short on-ramps with stop signs, tight curves and no shoulders. Merge and rear-end collisions are characteristic of this route.

Colorado Boulevard

The city’s main street through Old Pasadena and the Playhouse District carries dense pedestrian and bus traffic with frequent left turns and parking maneuvers.

Lake Avenue and Fair Oaks Avenue

North-south arterials connecting the 210 to South Pasadena and Altadena; red-light and left-turn collisions are commonly reported.

Common collision scenarios

• Merge collisions on the Arroyo Seco Parkway’s short ramps.
• Sideswipes at the 210/134/710 interchange complex.
• Pedestrian collisions in Old Pasadena, especially evenings and weekends.
• Event-day collisions around the Rose Bowl and Arroyo.
• Cyclist collisions on Colorado, Orange Grove and the Arroyo routes.

Courts, hospitals and local practicalities

The Pasadena Courthouse of the Los Angeles Superior Court handles local civil, criminal and traffic matters, though unlimited injury cases are frequently assigned downtown. Huntington Hospital in Pasadena is a Level II trauma center serving the San Gabriel Valley.

Accident types and injuries

Pasadena questions

I was merging onto the 110 Parkway from a stop-sign ramp and was hit. Am I automatically at fault?

No. Merging drivers must yield, but drivers on the Parkway must also obey the posted speed and keep a lookout. Fault is apportioned on the facts, and the Parkway’s unusual design is well known to CHP investigators.

A collision happened on a street closed for the Rose Parade. Who investigates?

Pasadena PD, often with assistance from other agencies during the event. Traffic-control plans and the large number of cameras and spectators can provide evidence; act quickly to preserve it.

How do I get a Pasadena PD collision report?

Through Pasadena PD’s records section with the report number or the date and location. Reports are released to involved parties and their representatives, typically within several business days.
