Where’s the O’Callaghan bridge sign?

I've traveled the Mike O'Callaghan - Pat Tillman bridge dozens of times since it opened and I just assumed that a big green highway sign announcing the entrance to the bridge was to come.

Now I'm beginning to wonder. It's been a couple of years and nothing yet has appeared.

There exists a nice sign carved into the bridge itself, but it can only be seen by walkers who have taken the time to park and walk the span of the engineering marvel. From the highway, no sign exists.

Seems to me there should be. I imagine the staff at Sen. Harry Reid's office could easily make this happen. I think they should.

PS: Also, there is no line marking where Arizona stops and Nevada begins. Seems like an oversight. Can we do something about that, too?
