Ahhh...great pic of the bridge Malcolm. I've tried on several occasions to capture it, without any great success. It certainly looks interesting at that time of day with the lights on and no traffic. I'd still love to be able to stand in the middle of the road and get a pic since it's so symmetrical. Perhaps I'll leave that for you to do on your next trip there. Just make sure you have lolipop man with you to stop the traffic.
I've often thought to have someone in a vehicle on one side of the bridge stop the traffic, since it's only a one lane bridge, and then you have your camera set up in the car on the sunroof (or a jeep without the hood) on the other side and then you can take the pic. The other thought of course is a helicopter hovering just overhead. Would take a little planning and just a thought but nothing is impossible.
