Worthwhile subject choice. Try using your favorite post processing program (Photoshop, GIMP, etc.) to adjust the white balance. This will remove the color cast and make the bridge stand out better. You might try to crop a good portion of the sky and water to emphasize the subject also. Look forward to seeing more.
Tim, you've captured a nice image but I agree with the by Kurt given above comment. I've downloaded this image and I've tried to edit your image by means of a photo-editor. It was relative easy job to enhance. Thanks for posting.
