I visited this location with the intention of capturing it at sundown just as the bridge was lit and with some ambient light still remaining in the sky. Having waited until 9.15 the bridge still wasn't lit and the sky was almost black so I left. I went via the road bridge and as I reached halfway along the lights came on much to my annoyance, had the sky not been so dark I would have gone back but instead (for now) I'll just have to settle for these daylight versions.
