I am one of the volunteer reviewers for geocaching.com. I was just reviewing your recent submission.
I hate to be the one to mention this BUT with the way things have been going lately, there is an extreme sensitivity to caches on or near bridges at this time. One state's authorities have contacted geocaching.com to ask that none be posted - people saw someone crawling around bridge supports, called the police to say a bomb was being planted. It was only a micro cache being hunted. Ouch!
If your cache is in a public park separated from the bridge by a fence, or is otherwise both safe and legal, please don't hesitate to reply referencing the cache GC code. You can reach me via E-mail me at the address below.
If your cache is on or near any part of a bridge that carries vehicular traffic, then placing a geocache is not allowed. The DOT (Department of Transportation) regularly inspects all bridges and they have stated that they do not want geocaches on or near any part of a bridge.
