Road and Highway Reference Sites

I mainly used AAroads for signage information over the years.  What sites have you all found useful for road and highway information?  Here are some of my favorites:
-  This is a good site for US Route logs and description on signage history.  Not many pictures but not short on fact and figures.  This site actually has a ton of information on the old and modern Florida Road system.
-  This site is shows almost all the historic and current end points for US Routes.  It has literally every US Route that existed on greatly defined map.  This is probably the best site for finding historic road alignments and end points.  Lots of signage photos are here as well.
-  This a great site for information on the Interstate System.  This is very similar to USends except with a larger emphasis on photos instead of maps.
-  Not exactly the best looking site but this guy did a ton of research into the New Mexico Highway system.  This is one of the harder states to get accurate highway information on and this guy has basically everything you could want that is New Mexico.
-  This is a great site on Route 66.  I used this site as a reference for a lot of the Old 66 road alignments which detailed extensively, or at least more so than I can find on most sites.  This sites has a lot of reference maps.
-  Another good Route 66 site that has a lot of information, photos and maps.  Also very good for old 66 alignments.
-  This site hasn't been updated in a long time but contains a ton of information and photos on Arizona Roads.  Since the system hasn't changed much in rural areas most of the information still accurate.  There is some highly detailed maps of Arizona and New Mexico along with a nice goof signage stub.
-  This is a very good site for anything highway related to the state of Connecticut.
-  An excellent site for anything related to California Highways.  This site is mostly informational, so if you are more into pictures rather than reading it isn't for you.
-  A very well put together and good looking site for Michigan highways.  Contains a ton of information that is very organized.
-  I saw someone suggest this here on the forum.  Very cursory information but it gives you ideas what to look for a quick road trip adventure on the twisties and turnies.
-  Solid site on US Route 6.
-  A solid site on the often overlooked US 89.


Great site, hosted by Steve Alpert (Alps). Lots of photos, lots of history, lots of everything.

Some of my go-to highway sites: (Really good page about highways in Iowa, including tons of history) (The Illinois highways page, really useful when I was looking for history about highways in IL) has the same author as the aforementioned Michigan Highways page, and the content is equally extensive and useful.

I also use usends, the Michigan Highways page, and Kurumi's site mentioned in the OP.

EDIT: whoops, misspelled one of the links. All better now.
Davenport, IA -> Valparaiso, IN -> Ames, IA -> Orlando, FL -> Gainesville, FL -> Evansville, IN


I try to link to relevant road sites on a state to state basis on the newer guides for AARoads.

Those include Steve Anderson's web sites, which are a great resource for highway history and backgrounds:

Other worthwhile sites include Jeff Kitsko's PAHighways:
Mark Sinsabaugh's NY Routes:
Oscar Voss' Hawaii Highways:
etc. etc.


CalTrans is where I go for project information.  There are usually more links to be found when digging around that wind up giving even more detail.  Here's an example using District 1's webpage:

For fun drives via YouTube it is hard to beat Freeway Brent's offerings.  Doing speeded up camera work, Brent eats those miles up in a hurry!

US 101 is THE backbone of the Pacific coast from Bandon OR to Willits CA.  Industry, tourism and local traffic would be gone or severely crippled without it being in functioning condition in BOTH states.

-  Usually I'm not a fan of how most DOT sites are laid out but this one is pretty user friendly.  It is pretty cut and dry but has a ton of historical maps of the Nevada Highway, it basically has every single year back to the 1910s scanned on PDF.

If you like the historic Nevada maps, you might try looking at this site:

It's the same map collection as NDOT's, maintained by the map library at UNR. While the maps aren't PDFs you can download, they are in at much higher resolution and are displayed in a JPEG viewer format that allows high-quality closeup viewing.

Wikipedia can be a great source of road information, depending on the state. A lot of the information on Oklahoma roads I've contributed there has not previously been on the Web in an easily accessible form.

Ditto with California. is a semi-accurate indicator of how good a state is doing: the lower the omega, the better quality coverage there generally is. has all of the California Highways and Public Works journals, free for download. There's other gems like this scattered around the Internet, if you know where to look.



Would this be a pinnable thread?

At about age 8 or 9, when I really started absorbing information about roads, and even things today, Wikipedia has always been good, and a place Ive gone to a lot to retrieve information about roads. As for proposals, I have used various different sites to learn about proposals, and for upcoming projects, DOT websites are always good. I've even learned some things from some of the threads on here, as well.
Now alternating between different highway shields for my avatar - my previous highway shield avatar for the last few years was US 76.




And a highway will be there;
    it will be called the Way of Holiness;
    it will be for those who walk on that Way.
The unclean will not journey on it;
    wicked fools will not go about on it.
