Ordon Bridge

The Wooden/Steel Bridge
If you go north of Ordon Spring there is a wooden bridge about thirty meters long and two meters wide. It has steel cables and no matter how much you try you can't cut it down so it is an ideal wooden bridge. It joins Faron Woods and Ordon Woods/Ordon Village together which means if it wasn't there you wouldn't meet Midna and complete the game. You also wouldn't:
