If anyone would like to see how I went through the normal levels, here are 2 .zip files with my bridges from the two separate times I went through the normal levels.
The second .zip is the second time through, and I tried to avoid the use of suspension bridges wherever possible. It is also much more optimized than the first time, and the bridges (for the most part) cost less.
The easiest way to use these files is to back up your "bridge" folder, then extract the files into the original "bridge" folder, overwriting files. Then all you have to do is 'Start Game' and select each level to see how I did it.
Wow, that was a long post for a fairly simple plan.

Have fun! I'd be much obliged if others followed my example and posted their bridges!
Sorry for the late reply. I haven't been on the board for about a week.
