Why does Eleanor St have a height restriction?

I was thinking about this today when I drove by on Florence... Eleanor St north of Florence has a height restriction as seen above, but all the times I've driven through there I can say I've noticed anything with low clearance, other than the warning signs. No low wires, no overhangs, obviously no bridges. And just to make it a bit ironic, the warning signs have obviously been hit a few times, including at least once by an outbound truck.
