See, I think this is the difference between an elite ninja and a regular ninja. Naruto has only the shadow clone jutsu, and non-elemental jutsu. He is not building up variety, this ninja however is. He seems to have mastered wooden techniques, and his experience shows.
I bet that technique was just a simple pillar growth technique, but he mastered it to such a level, that he can make these structures. It would not be a bad idea if Naruto went for variety too.
In anycase, lets get to the bridge soon.
