First responders are working to rescue some nurses and a pilot after a LifeFlight helicopter crashed outside Nashville Saturday.

The Wilson County Sheriff's Office says the crash happened in the 7100 block of Cairo Bend Road in Lebanon, TN.

"We are asking motorists to please avoid the area and seek an alternate route to allow emergency personnel to safely and effectively manage the scene," the agency said in a social media post.
