Westbound Interstate 8 east of Lakeside turned into a standstill today after a head-on crash left at least one person dead and scattered wreckage across the freeway. California Highway Patrol officers rushed to the scene, shutting down all westbound lanes while emergency crews and investigators moved in. The closure also took out the westbound Dunbar Lane on-ramp and quickly snarled the evening commute as drivers were warned to brace for delays.
According to The San Diego Union-Tribune, CHP described the wreck as a head-on collision involving two vehicles, reported just east of Lake Jennings Park Road. Debris and mangled car parts were strewn across the westbound lanes, and traffic was being diverted off at Dunbar to Olde Highway 80 while crews worked to clear the scene.
How Drivers Were Detoured
CHP directed westbound motorists to exit at Dunbar, follow Olde Highway 80 and then re-enter I-8 at Lake Jennings Park Road while tow trucks and cleanup crews did their work, a detour pattern Caltrans has used before on this stretch. 10News has detailed that same routing during recent closures between Dunbar and Lake Jennings Park Road.
Crash History On This Stretch
This portion of I-8 east of Lakeside has seen more than its share of serious crashes in recent years, including a fatal rollover east of Lake Jennings Park Road in May 2025 that required an extended cleanup and shut the freeway for hours. The Times of San Diego reported on that earlier wreck, highlighting how quickly trouble on this corridor can gridlock East County traffic.
CHP investigators remained on scene Thursday evening and had not released the names of any victims or a probable cause, according to The San Diego Union-Tribune. Authorities asked anyone who saw the collision or captured video of it to contact CHP as the investigation continues.
Drivers headed through East County are being urged to allow extra time, follow posted detours and keep an eye on official traffic channels such as Caltrans QuickMap and CHP advisories for live updates. Officials said more details will be released as investigators wrap up their on-scene work.
