Add ons wanted for FSX

I think, we need an addon for accessorizing the highways and roads with road signs and boards etc. Maybe even flyovers/Overpass. Don't know how hard that would be.. I don't mean specific objects.. but generic ones that would either replace the default road textures or add to it.http://www.southeastroads.com/i-085a_ga.htmlWhen I max out the Autogen, Its very nice in places like Seattle.. But not so good in the Dallas Area. Dallas looks like some place in Africa.:)
