Two women were critically injured when their personal watercraft struck the Long Island Rail Road bridge over Reynolds Channel on Monday evening off Long Beach, police said.

Nassau County police said the force of the collision knocked both women into the water, unconscious. Both were saved by a father and son who were fishing near the accident scene, with assistance from a couple who used their own personal watercraft to transfer the victims to shore — where they were transported to a hospital by the Long Beach Fire Department.
