The frantic father, identified as Abdel Elkarhat, ran for the help when the mother went into labor while in the tunnel, near the New York side, just after 7 a.m.
Port Authority agents George McCann and his partner Jean Bernard rushed to the car.
They carefully helped new mom Soukaina Nekhlaoui deliver the baby boy and even created an "oxygen tent" around the baby to protect the newborn from car fumes.
Both the mother, from Lodi, New Jersey, and little Nassim Mohammed Elkarhat were taken to New York Downtown Hospital in stable condition.
