405 Freeway Accident Today Live: Updates On Injuries, Shutdowns, And Traffic Alternatives
The southbound I-405 near the 101 interchange ground to a halt this afternoon after a multi-vehicle collision involving at least three cars. Emergency crews responded promptly, stabilizing at least one patient who was transported by helicopter, while authorities temporarily closed lanes to clear debris and investigate. Drivers approaching the corridor should anticipate significant delays, use real-time navigation tools, and consider alternate routes until the scene is fully cleared.
Law enforcement and transportation agencies provided periodic updates throughout the early evening, confirming that the freeway remained partially restricted as crews worked to remove wreckage from the fast-moving carriageway. Below is a detailed breakdown of the incident, the response effort, and practical guidance for travelers seeking to avoid or navigate the affected segment.
Initial reports from the California Highway Patrol indicated that the collision occurred shortly before 3:00 p.m. in the northbound carpool lane just north of the Century Freeway. Dispatchers classified the call as a major incident, prompting additional units, including air support, to the scene. Responding paramedics triaged at least one critically injured patient on-site, stabilizing them before airlifting the individual to a nearby trauma center.
Although officials did not immediately release names or release details due to pending notifications of next of kin, a CHP spokesperson noted that one patient was transported by helicopter, while others received care at the scene. Preliminary assessments suggested that multiple vehicles were involved, with one car sustaining significant intrusion that required extrication efforts.
By mid-afternoon, the California Department of Transportation had activated its incident response plan, deploying tow trucks, litter removal teams, and traffic control personnel. The southbound side of the highway was reduced to a single lane in each direction during the peak of the cleanup, while the northbound carpool lane remained closed for several hours. Caltrans advised travelers to expect delays of forty-five minutes or more through the affected corridor, with backups extending as far north as LAX and southward toward Long Beach.
As work progressed, officials provided periodic updates on social media and through regional traffic management centers. At approximately 5:30 p.m., a CHP public information officer confirmed that one lane of southbound I-405 had reopened, allowing for improved flow but urging drivers to remain alert and cautious. Crews continued to work into the early evening to remove damaged vehicles, repair signage, and sweep the roadway for debris.
The incident created ripple effects across the broader regional network, with traffic signals adjusted to accommodate increased volume on parallel arterials and collector routes. Commuters heading toward LAX, the South Bay, and Orange County were strongly encouraged to allow extra time and seek alternatives to the freeway system. Several transportation agencies issued alerts recommending detours and public transit options throughout the evening peak period.
For drivers navigating the area, officials suggested multiple detour options depending on origin and destination. Motorists traveling northbound were advised to remain on the mainline where possible, while those needing to exit toward Century Boulevard or surrounding neighborhoods prepared for moderate congestion on local streets. Caltrans recommended real-time use of navigation apps and the 511 traveler information system to select the fastest available route.
Specific guidance included using local streets such as Pershing Drive or West Century Boulevard to bypass the most heavily affected segments, with particular caution near entrance and exit ramps where merging traffic concentrated. Public transit agencies reported increased ridership on bus routes that parallel the corridor, with Metro and other operators adjusting schedules where warranted to accommodate diverted passengers.
Highway operations personnel emphasized that the quick clearance of damaged vehicles and debris significantly contributed to the reopening of lanes. Towing contractors worked in tandem with Caltrans and CHP to load and remove vehicles from the active travel lanes, restoring capacity as quickly as safety allowed. Crews also replaced several damaged signage panels and reflectors to ensure clear guidance for drivers re-entering the highway.
A spokesperson for the City of Los Angeles Bureau of Street Services described the collaborative effort as "a coordinated response involving multiple agencies working toward the safe and efficient restoration of the freeway." Emergency medical services maintained a presence through the night, with at least one ambulance stationed near the scene until all patients were transported and the roadway was deemed safe.
By late evening, traffic flow had largely normalized in the immediate vicinity of the collision, though residual congestion persisted for several miles in both directions. Officials cautioned that additional incidents could occur as drivers adjusted to changed conditions, urging patience and vigilance. Commuters were reminded to avoid rubbernecking, keep headlights on in low-visibility conditions, and report any stalled vehicles or road hazards through appropriate channels.
Authorities indicated that they would continue monitoring traffic volumes and incident clearance progress throughout the overnight and early morning hours. Depending on the extent of damage to guardrails, barriers, and pavement, additional lane restrictions might remain in place during the overnight recovery and resurfacing operations. Regional traffic centers encouraged the public to check official websites and social media channels for the latest updates before traveling.
Travelers moving through the region overnight and into the following day were advised to utilize real-time traffic cameras and incident feeds to assess current conditions. Transportation agencies emphasized that flexibility in trip timing and routing would help reduce exposure to lingering delays. In the days following the incident, transportation planners typically conduct thorough reviews of response timelines and operational procedures to identify opportunities for improvement.
For the thousands of drivers affected, the incident served as a reminder of how quickly routine commutes can be disrupted by unpredictable events. As reconstruction efforts continued into the night, the focus remained on restoring safe and reliable mobility across one of the region's most critical transportation corridors.
