Facts are that the ship never had a “green light”
After receiving the flashing amber approach light indicating that the bridge operator was aware of the vessel, the captain lined up on the centerline and maintained a speed of 5 knots.
My comment was a bit of nautical humor that some folks picked up on.
FACTS ARE THAT THE SHIP HAD A GREEN LIGHT.
As the vessel neared the bridge, the signal lights on the bridge were flashing red and the lift span was being raised. When the vessel was approximately 0.75 to 0.5 nm from the bridge, the signal lights changed to solid green and the lift span was in the fully-raised position. With the centre line of the vessel lined up with the bridge signal lights, the vessel proceeded under the bridge.
