A woman gave birth in her car Thursday on the left shoulder of I-270 southbound between Route 118 and Middlebrook Road in Germantown.

Minutes before 6:30 a.m., police received reports of a medical emergency, and a rescue crew rushed to the scene. But before they got there, the woman gave birth to a baby girl. Both were transported to Shady Grove Adventist Hospital in Rockville, according to Maryland State Police.

Montgomery County Fire Department assistant chief Scott Graham tweeted about the baby’s birth.
