I recently discovered that only three US highways under 100 weren't represented in my national collection: US22, US23, and US40. I have all three of these photos in state level, collections, though. So, broadly speaking, I have a photo of all the US highways from 1 to 101! And I didn't realize it until yesterday. I decided, in that case, that I should put some pages up for those last three remaining US highways, on the national-scale page. So go check them out! With this, every US highway from 1 to 101 is now represented on the website!
I have many more US highways numbered above 101 that I still have to photograph. But I'll get to them in time!
