The first one, I got kinda overconfident and thought that obsidian skin potions were a great hellbridge. Nope, lost that one.

The second fight is still legendary in Terraria history. As a wee newbie, with little knowledge of Terraria and a fairly short hellbridge, I used the Ruby Staff and Molten Armor to destroy the Wall just before I reached the end of the bridge. It was legendary.
