Why Do Highway Closures Happen After Serious Crashes?
Routes carrying regional traffic, like Interstate 40 near mile marker 236, can experience major disruptions when serious crashes occur. When injuries are reported, crews often need full access to the roadway to provide care and secure the scene.
Closing lanes or entire directions of travel allows space for emergency vehicles and helps protect those involved. It also reduces the risk of secondary crashes as drivers approach the area.
Traffic detours are commonly used to move vehicles around the scene. While this can help keep traffic flowing, it often leads to delays as nearby roads handle higher volumes until the highway reopens.
