It has actually dropped since the 55MPH blanket law was replaced and speeds of up to 75MPH are allowed on certain highways.

I understand out west there are some highways that are not marked for speed limit at all.

Daytime speed limit, “Reasonable And Prudent,” nighttime speed limit 75 mph. Wyoming, I seem to recall but could be mistaken.

I don't think I've come across any roads with no speed limit at all. There are places out west where the speed limits are variable. The signs are electronic and the speed limit changes with the weather conditions. I-80 across Wyoming has long stretches like that. As the wind speed goes up, the highway speed limit goes down.
