What Causes Major Freeway Delays After a Crash?
Crashes on busy freeways often lead to lane closures while crews respond and clear the scene. Even a single blocked lane can slow traffic for miles, especially during peak travel hours.
Investigations may take time, particularly when serious injuries or a death are involved. Crews may need to document the scene, remove damaged vehicles, and ensure the roadway is safe before reopening lanes.
Large vehicles, such as big rigs, can make the situation more complex. Their size and weight can block multiple lanes and require special equipment to remove. These factors can extend delays and impact nearby routes as traffic is redirected.
