You probably need to increase your depth of field, ie higher f stop number. That one was shot at F3.5, so you probably need to stop down, say F8 or more. With a small aperature, you need a longer shutter speed. The EXIF shows 1/60, so I assume you hand held it? Try using a tripod.

I found even when using a tripod, my shots of the vectorial elevation night shots were not sharp enough. It's either the vibrations from the cars on the bridge or not using a remote to trigger the shots. I even used the mirror up feature.
