The woman presumably thought she could help when she stopped her vehicle along Interstate 70 in Frederick County early Wednesday. But her effort led to her own injuries after she mistook a jersey wall for a median, jumped over it, and fell between 100 and 200 feet into the Monocacy River.

The woman, whose name wasn’t released, and was taken to an area shock trauma unit. Her condition wasn’t immediately known.

She was trying to help two other drivers of trucks, police said, who had been involved in an earlier incident.

That crash happened just before 5 a.m. when a tractor trailer rear-ended a dump truck along the westbound side of the interstate. The tractor trailer jackknifed and the dump truck turned over, according to Maryland State Police.

The nurse, police said, pulled up “shortly after the collision, ran up to the scene to assist and jumped over a jersey wall.”

“Believing that there was a median on the other side,” police said in a statement, she leaped into the river.

The driver of the dump truck was also taken to an area shock trauma unit. The other driver was also injured and transported. The conditions of those involved were unknown.

Police said the incident is under investigation. Part of the highway was closed throughout the morning as crews worked to clear the area. Crews are working to repair the bridge as well.

Major traffic delays are hitting Interstate 70 near Frederick County after two incidents, including one involving a crash of two trucks and a woman who fell 40-feet over a bridge after stopping to try to help the truck drivers.

Few details were immediately available and it was not clear the conditions of the three people involved in the incidents. They were all transported to area hospitals, according to the Maryland State Police.
