NEW YORK -- Officials say a baby girl was successfully delivered in the backseat of an Uber car parked at the mouth of the Lincoln Tunnel.

The Port Authority of New York and New Jersey, which operates the tunnel, says the birthing process began around 5:15 p.m. Monday while the baby's 32-year-old mother was riding in the ride-hailing company's car.

The driver flagged down two Port Authority officers, telling them he had woman in labour who "couldn't wait."

The Port Authority says an employee delivered a healthy baby in just minutes. It was the second baby senior agent Greg Nimmo has delivered while working for the authority.

The mother, who had been travelling to the hospital from Hoboken, New Jersey, was transported to a hospital along with her new daughter.
