A large pothole that formed on the southbound lanes of State Route 14 in the Antelope Valley region of Los Angeles County has forced the closure of multiple lanes, according to the California Highway Patrol. The pothole is located just south of Palmdale Boulevard, and only the No. 1 lane remains fully open as Caltrans crews work to fix the issue.

Why it matters

Potholes and other road hazards can pose serious safety risks to drivers, especially on major freeways where high speeds are common. The closure of multiple lanes on SR-14 is likely to cause significant traffic delays in the Antelope Valley area until the pothole is repaired.

The details

CHP officers reported that the three rightmost lanes on the southbound side of SR-14 have been closed due to the large pothole. It's unclear what caused the pothole to form or how long it will take for the lanes to fully reopen once Caltrans crews complete their repair work.

  • The pothole was reported on April 9, 2026.
