Massachusetts State Police helped a couple safely welcome a new baby after the mother went into labor while the pair were stuck in traffic on Interstate 93 north in Milton Friday evening.

The incident occurred at around 7:30 p.m. when police found the couple’s vehicle at the Granite Avenue ramp and helped to make sure that emergency medical services (EMS) could safely reach them, the department said in a statement. Working quickly at the scene, EMS helped to safely deliver the baby.

With the mother and child in stable condition, troopers escorted the ambulance through traffic to Boston Medical Center.

“The State Police would like to congratulate the couple on the birth of their child, and thank our EMS partners for their swift response,” the department said.
