Great Naruto Bridge

The Great Naruto Bridge is a long, wide bridge that was most likely in construction at the beginning of the Naruto plot. Team 7's first C ranked mission took them to the Land of Waves, the location of this bridge. The man in charge of the bridge's contruction is Tazuna, who wanted to make this bridge in order to break Gato's monopoly over the country's trade.

Role in the Mission to the Land of Waves Arc
The bridge, along with encouraging new trade, also was intended to be a symbol of courage, since Tazuna placed his life on the line in order to complete the bridge. Its construction met rough times when Zabuza and Haku slaughtered the construction workers prior to completion. The bridge ends up being the site of Zabuza's and Haku's death, along with the mastermind Gato. Once completed, Tazuna decides to name the bridge after Naruto, who, according to the bridgebuilder, gave the country the courage it needed to stand up to Gato. The bridge does not make any further appearances in the story.
