1955 Road map, pre-Interstate
I like poking around looking at old maps. These older main roads are usually the most interesting to travel. 1955 Road Map

Thanks for posting that, it surprises me just how many federal highways are newer than that, not just the interstate highways. I live in a town in Louisiana where 2 federal highways cross, only one appears at all on the map, and it is just a 50 or so mile long stub, not the 400+ mile long highway it is today. I know these 2 highways date back to at least the 1960's with their current numbering, I just don't know when in the decade or so after that map you linked to that they were added.
