I routinely use Google Maps to get directions to places just about anywhere, and I've noticed some weird screw-ups on the route numbers for roads.  Google likes to put a route number on many routes that are no longer part of the highway system.  Also, they like to give state route #'s to business routes.  Examples I have for both are in Barstow, CA.  On Old Hwy 58, they have route 58 cosigned with route 466, but they have the route incorrectly signed as US Hwy. 58 and CA-466.   Another one is the Business Loop 15 on Main St., but it is signed on Google as having CA-15 signage.  This intrigues me simply because it probably confuses many average drivers.  Any other incorrect route numbers that you all have noticed with online mapping?  Doesn't matter if you use Google Maps or Mapquest or whatever.

Google Maps uses interstate shields on freeways in China.

Also, apparently Virginia has a VA 58 between two discontinuous pieces of US 58.

Don't they do that in Canada as well?

They used to in Quebec, but now autoroutes for some reason a generic route shield similar to Alberta's provincial route shield.

In Thunder Bay, they still have highways from the mid 1990s.
(Highway 11, 17 A and B, and the re-routed 11/17 - 130 corridor)

Google Maps has resurrected many of the decommissioned PA routes that were axed after WWII like PA 908 and PA 766.

They also show U.S. 90 as State 90 quite often, but I think those are more quirks whereas the decommissioned routes, like U.S. 81 on Interstate 35, are just the results of bad researchers working at NAVTEQ and TA.

Here's one that bugs me about Google maps.  I don't see any OR-208 signs in Beaverton.

Yahoo Maps shows decomissioned (non-existent) routes in Washington. For Wikipedia editors, this can be quite useful.

* NE 2 extending beyond the western terminus of its eastern half over US 77 and US 6:
http://maps.google.com/maps?hl=en&ie=UTF8&ll=40.800686,-96.744318&spn=0.029887,0.087891&z=14

* Link 93E marked as NE 93, compare http://maps.google.com/maps?hl=en&ie=UTF8&ll=40.821277,-97.700465&spn=0,359.824219&z=13&layer=c&cbll=40.821277,-97.700465&panoid=wrGzpFssyRdRRXe0wL6cNg&cbp=12,107.78610789246613,,0,10.25354772566927 with http://maps.google.com/maps?hl=en&ie=UTF8&ll=40.849398,-97.688713&spn=0.119462,0.351562&z=12

* US 34 demoted to NE 34 west of "NE 93"

* Shows a lot of routes Iowa decommissioned in 2003.

* Lots of errors with Missouri's lettered routes.  Take this section along Rte M in Jefferson County:
http://maps.google.com/maps?hl=en&ie=UTF8&ll=38.358821,-90.427694&spn=0.030959,0.087891&z=14
First, "Hwy MM" (the new 60 mph expressway) is actually Rte M.  Second, "Hwy M" is now Old Highway M.  Third, I have no idea where "State Road O" came from.  In other places they are incorrectly called county highways.

* Still shows MO 21A  around Crystal City, and even on two different alignments:
http://maps.google.com/maps?hl=en&ie=UTF8&ll=38.216267,-90.419798&spn=0.03102,0.087891&z=14

* Not completely incorrect, but the MO 364 freeway is actually the Buzz Westfall Highway in St. Louis County, but I think most people refer to it as the Page Avenue Extension

* Shows former alignments of state highways in St. Louis city that have not been revived yet, like MO 340, MO 267, and MO 231.  What's strange though is the latter two also appear on some of MoDOT's traffic county maps.

Google Maps has South Fulton Parkway signed as US 29, instead of the US 29 Alternate. Also, Google Maps has SR 70 following Campbellton-Redwine Road to Cascade-Palmetto Highway. SR 70 currently follows Cascade-Palmetto Highway (SR 154) and South Fulton Parkway West to Campbellton-Redwine Road South to Newnan, Georgia.

http://maps.google.com/

Type in "South Fulton Parkway, Fairburn, Georgia 30213" to see what I'm talking about.


Be well,

Bryant

I don't think Google has an ALT shield at all... so US-29 is likely the best they can do with their current set of graphics.

Okay, didn't know that. It's misleading, though.

Not a route numbering in consistency, but a graphical one:

In Latin America, Africa, the Middle East, and India, all federal highways are colored freeway orange, whether they're limited access or not.

This problem used to also exist in Canada with the TCH, but they fixed it there.

Mapquest is even worse. They have old state highways (especially in NV for some reason) all over the place, decommissioned US routes are a frequent visitor, and tons of neighborhoods and names of stuff (ex tunnel names) are marked as towns.

Didn't Nevada renumber its state highways a number of years ago?  I remember seeing it in old Rand-McNally atlases, but I think that was before Mapquest even existed.

Yeah, back in the 1970s (I'm tempted to say '74). Mapquest doesn't have many of those, thankfully, but they do have a lot of highways decommissioned in the 80s, 90s, and 00s.

Google Maps doesn't have any sort of ALT, Business, etc. banners, so in western MD it alternates between US-40 following I-68 and following US-40 ALT. It also has some roads that just don't exist anymore, and it has Maryland Route 9, which has never existed...

Not a route numbering in consistency, but a graphical one:

In Latin America, Africa, the Middle East, and India, all federal highways are colored freeway orange, whether they're limited access or not.

This problem used to also exist in Canada with the TCH, but they fixed it there.

For a while Google Maps did the same thing in the United States. US-19 in West Virginia, for example, was marked as a freeway, even though it isn't.

Close to home, Spur LA 437, as well as the part of Columbia Street in Covington that carries mainline LA 437, are marked as LA 25. LA 25 hasn't been on Columbia Street for decades. Also, for a long time Fish Hatchery Road (the locally-maintained part) was shown on Google Maps as LA 1072, a designation actually existing in Washington Parish.

Spokane, WA

Apparently there's a US 2 and SR 2, along with a US 395 and SR 395.
