A woman gave birth to a baby boy on the Massachusetts Turnpike on Sunday.
State police say they received a call Sunday night from a Framingham couple, saying the woman was in labor.
The couple had been driving east and pulled into a parking lot near exit 18.
State police say troopers and Boston EMS responded. They were unable to get the woman to the hospital before she gave birth. State police say she delivered a baby boy in the back of an ambulance around 7:35 p.m. The woman and baby were then taken to Massachusetts General Hospital.
State police say it was "excellent work by all involved."
They have not identified the couple.
No other information was immediately available.
