It has now been 6 minutes since I posted that message, and they're still blurry. On your site, they're quite clear, though.
Just curious, are you trying to view the pdfs in your browser?  Or are you downloading them first and viewing them in Acrobat?

I'm not sure I can get Acrobat anymore. Some of the recent updates to my PC over the past year or so killed a lot of programs for me.

Nevada URL updates:

Main NDOT page for historical state and county maps:
https://www.nevadadot.com/travel-info/maps/historical-maps

Historic quads:
https://www.nevadadot.com/travel-info/maps/historic-quads

I'm not exactly sure about the "better quality state maps" link; this is the start page for accessing UNR's "Historic Maps of Nevada and the Great Basin" collection and maybe it can be narrowed down from there but I couldn't figure it out quickly:
https://unr.dgicloud.com/islandora/object/nvmapscollection%3Aroot

The original link appears to have gone to the DeLaMare map library's digital map collection but at this time that is giving me a "migrating to new platform/back online shortly" message.

Not necessarily state maps, but Ohio has added to its digital archive

Aerial Imagery Archive
The office of CADD and Mapping Services has implemented a new innovative way to search for historic aerial imagery. You can now access the entire ODOT Aerial Imagery Archive through a single Google Earth (KML) file.

To use our Google Earth (KML) file you must have Google Earth installed on your desktop computer.

Next, all you need to do is download the Aerial Imagery Archive (KML) file.
http://tas.transportation.ohio.gov/Imagery/KMZ/ODOT_AerialArchive.kml

Now open the Aerial Imagery Archive (KML) in Google Earth and begin your imagery search!

We have structured the Google Earth (KML) file as follows:

Top level is sorted by DECADE
Second level under DECADE is sorted by YEAR
Third level under YEAR is sorted by DATE of imagery
Forth level under DATE is sorted by each IMAGE
The ODOT Aerial Imagery Archive contains over 500,000 individual images. Each image is represented in Google Earth as a single center point for each image. The image center point is displayed as a camera icon. The Google Earth time slider has been enabled for searching through specific time periods depending on the imagery loaded or toggled on. Also, when searching for images try to load specific years or single decades and not the entire aerial archive as this may result in Google Earth crashing due to the extensive amount of image points being loaded.

The aerial images available for download are not orthophotos therefore, will not overlay properly when loading in Google Earth or other GIS applications.

Yeah, UNR libraries has been undertaking a massive update/migration to all their digital archives over the last couple years. The NDOT map collection, originally hosted on the DeLaMare Library Map Collection site, was a better reference source cause their map scans were much higher quality than the PDFs on NDOT's website. The UNR maps were inaccessible for nearly a year, but they are now back online—however, they don't have the same direct categorization they used to, so you have to wade through other maps to find the road maps.
