I made a website where you can see my completed shield galleries for every numbered highway within Illinois, Iowa, Ohio, Indiana, and Michigan! Furthermore, if you click on any of the shield images, you will be whisked away to a new page for that highway, with information about the highway and a context photo that gave me the cropped shield image! There is also a national page, where I am showing my collection of MOST of the US highways and Interstates found anywhere in the United States!

Feel free to explore other parts of the site, like my detailed guide on interchange configurations, a glossary of roadgeek jargon, reflections on national parks I've visited, and more.
I achieved a major milestone during this month of October, 2024. My nationwide shield gallery now has a photo of every US Highway in the United States! Since that is now true, you can peruse the photos I have saved for each US Highway by going to my national page (http://www.paulacrossamerica.com/National.html). Click any of the shield images to see the context photo for where I got the shield image, and you can read a little bit about the US Highway and where I encountered it.
I also have taken pictures of every Interstate from 1 to 100 (whose construction is at least substantially completed). You can see those in the shield gallery on my national page (http://www.paulacrossamerica.com/National.html) as well!
