Hoover dam website states the rules for crossing the dam.
1000 rounds of ammo is specifically mentioned. Firearms are also mentioned as is the right to inspect. Dam rules says if you cant comply then dont try.
I don't normally check the website for every bridge or dam that I cross while driving in the continental USA. The thing that amazed me was driving for an hour and there not being a single sign mentioning any rules or regulations for the dam.
