Websites about the freeways themselves

[AsphaltPlanet]

Pardon my ignorance, but I am wondering, are there any other websites that are done in similar vein to dfwfreeways.info?

I notice that a lot folks take photos of signs and things. which is great, but I'd really love to see more photo sites that highlight the freeways themselves, and better yet, how the freeways intertwine with their surrounding urban or rural landscape.  There has to be some sites that I don't know about.

Any good links would be appreciated.
