Thanks so much Alex, I am going to try these suggestions and see if I can get a sharper image, however I still don't really understand about Hyperfocal distance.
With this shot of my night cityscape, its taken from an edge of a cliff, I always try to focus on the bridge structure, however I am not sure if thats where I should have the centre focus point, and I wonder if the buildings in the back ground cause confusion with the focus ?? anyway I will try suggestions here, and I very much appreciate them all.

I think you have a winning combination with these suggestions here.
If I were taking this shot, I would have performed the following steps after choosing the perfect location for composition - you may have done some of these:
- set the tripod on a stable surface, preferably concrete or stone
- set camera on liveview mode so the mirror would already be locked up (remember to cover the viewfinder)
- set ISO to 160 (something about 160 being a native ISO and [SUPposedly] sharper than 100)
- set exposure mode to aperture priority and set aperture to f/11 (sharpest on my 17-40)
- set my needle to the middle
- composed the shot properly
- check your lens and/or filters for debris, humidity, fog, etc and clean as necessary
- make sure all my tripod legs and ballhead screws were tight
- used a remote shutter release, RC-6 to capture the image
- bracketed by taking two more shots at -2/3 and +2/3
I'm guessing a proper exposure would have been somewhere in the 4s - 12s range with these settings.
I think the image is soft for several reasons, but the largest reason being the high ISO and the fact that you shot in JPEG. Start shooting RAW! Especially when shooting high ISO and using noise reduction in LR or PS. You will surprised by how much more information there is in a RAW image and how much you can manipulate it.
You have the right tools and it looks like you know what you're doing. It's a fine image, but it could improve by just tweaking a few things here and there. Good luck.
