Did someone forget the road?

This is Avenida Periferico, one of Mexico's City's busiest streets, which just happens to have a spine of these flyover-supports running down the length of it.

Very strange indeed. No obvious signs of any other work, like roadbuilding being done, as if someone had forgotten all about it.

A long week was rounded off in a lovely, relaxing evening with Sandra. A lot of laughing, as I recall.
