I went to take a look at the new bridge built across the Ave. of Sphinx at the Karnak end. It has been competed and you can see where some work has gone on to excavate the ares that were once under the bridge. I tried to walk down the provided steps to the avenue to take a good picture of the new bridge from the walkway, alas, I was approached by a guardian who warded me off, so I took my pictures elsewhere.
You can see in the photo that there are lights that run from Luxor to Karnak. I don’t know if they are working yet but they certainly seem ready to.
There will be many more bridges that will have to be built across the avenue before it will be a complete thoroughfare from Luxor Temple to Karnak Temple.
