usatr: United States select tourist routes

[si404]

in IL, East Dubuque, GRR goes both over the Julien Dubuque Bridge to the Iowa state line and follows IL-35 north to the Wisconsin border.

I think we removed it from IL 35 because it's not signed until you cross into Wisconsin.

it is signed in IL as of field check a couple weeks ago

that's new then

I noticed this system was upgraded to preview again.  I was looking at the Great River Road in Louisiana and had some questions.  Is this system joining US Interstates as a system where we include routes regardless of signage?  I'm having trouble finding signs for GRRbat.  I had never paid attention to this road, so I don't recall whether I've seen signs in person or not.

Also, how was the routing chosen for this route through Baton Rouge?  It doesn't seem to be signed, and the path doesn't match the route as defined in Louisiana statute, specifically the section between I-10 and I-110.  Was another source used besides the statutory routing?

A couple of weeks ago I drove the Great River Road between I-110 and LA 30.  I drove both the statutorily defined route and the route as it was in Travel Mapping.  Since neither was signed and no one has provided any reasoning to keep the route as it is, I've submitted a pull request to change it to match the legally defined route:

https://github.com/TravelMapping/HighwayData/pull/8575

Route defined here:  https://legis.la.gov/Legis/Law.aspx?d=207049

I assume that routes in this system are included regardless of signage?

There's another segment of the Lincoln Hwy signed in the Bay Area. I only saw this sign, on San Pablo Ave (CA 123) south of Cutting Blvd. I was headed southbound on San Pablo from Crockett, looking for markers for a different route, and this was the only Lincoln Hwy sign I noticed.

Additionally, the Tracy segment of the highway can probably be extended to the roundabout at Grant Line Rd & Business 205 due to this pair of signs on Grant Line.

Posted this a couple of weeks ago in the wrong topic:

Lincoln Hwy and some other routes in Illinois were updated recently, and now there are lots of broken concurrencies. Guessing maybe someone was using old files since many waypoints at state route/Lincoln Hwy junctions were deleted. Also, the Lincoln Hwy path was changed to make use of a closed connection here (US30_Osw).Related issue in Iowa, where the west end of Lincoln Hwy no longer has a graph connection with I-29/480.

Iowa & Illinois are very bad for coordinating points for the LH with existing highways. I had to allocate 2 hours, last week, to realign my "points" in both states to get my mileage right again.

In Wisconsin, the Great River Road is missing a point that US 53 has (GilSt), and the Lake Michigan Circle Tour is missing several of WI 32's points south of downtown Racine.

The Plymouth IN Lincoln Hwy segment appears to leave US 30 west of Wanatah and follow a mystery routing. Or maybe it's an entirely new branch, since the marker is different.

Some other signs have been lost to attrition. https://www.lincolnhighwayassoc.org/map/ shows how the actual LH went.
