Every day I ride on Camino Del Norte, which is generally a north/south road. To the west is another north/south road called Camino Del Sur. They bend around and meet at the top, so if you go far enough north on Camino Del Norte, eventually the road becomes Camino Del Sur and you're riding south.
And at the place where they meet, there's a street sign with both names; on the west side it says Camino Del Sur and on the east it says Camino Del Norte
