Some of the mile roads might even be considered unpaved minor highways! :lol:

Once we get the checkbox for unpaved, that will be easier to handle because you can label it as a primary street if that's what it is and still mark it as unpaved so people can avoid it if they prefer.

I'm in the region pretty much devoid of county highways. I'm having the opposite problem down here. Some of the "primary streets" as would seem to be depicted on the State website are not paved. Most of that information is helpful, but when I find gravel roads I just set them as gravel roads. Maybe it gets plowed a bit sooner than its neighboring gravel roads in the winter, but I'm still not gonna drive on gravel. There is value in sorting this stuff out.

Lol. They can't afford to maintain them anyhow.

You may want to look at any of those that you're changing from Street to make sure they aren't county highways. I had to add the county highway alternate names to the ones in northern Michigan because they weren't on there as alternate road names from the import. I noticed you added them to the section of the roads around Cheboygan that I wasn't able to do yet, so you probably already noticed that. I'm not sure how they are in southern Michigan as I haven't looked down there yet.

And I definitely agree with using Primary Street on regular roads that have a more important use than normal streets. Any road that the majority of traffic would use to get from point A to point B could probably be labeled as a Primary Street without being incorrect. As long as point A and point B are not close to each other (eg. the majority of traffic from one block to the next would use the same route, but that doesn't make it a primary street). :) Roads labeled "County Road XXX" on the street sign probably would make sense as Primary Streets as well, though I am not sure that I've had any specific experience driving roads with that label, so I am not sure how accurate that is.

Oh, sure, don't hesitate to upgrade certain local roads to "primary street" if it makes sense to do so. That's pretty much a judgment call. Last I looked, Detroit is in pretty bad shape with respect to Primary Streets.

Thanks for the explanations. I'll upgrade those roads again tonight.

I still think it makes sense to use "primary street" on some of the more useful county roads. I've done this along the I-94 corridor west of Ann Arbor and it makes the map more informative.

Hah, and here I thought they were just being nice to us by choosing not to include anything our clients might pronounce as "East"!

A quick note... I think you meant that Primary Streets are intra-city rather than inter-city. :)

Just to throw this in for anyone who may be reading this and doesn't know much about Michigan's roads... The county highway system was started when a US route (US-31) was moved when I-196 was built. The Blue Star Highway was then no longer marked on the state highway maps because it was no longer a US highway. The owners of a hotel along Blue Star Highway started getting cancellations because visitors couldn't find them on the highway maps, so they spent time trying to get the highway added back. After some time, they got a senator to help get a test system in place that marked Blue Star Highway as County Highway A-2 on the state highway maps in 1970. After testing throughout the year, the County Highway system was made official with regions of A-H set up. The region letter corresponds to the highway name. Since that time, county highways were added for all regions except region E, which represents the "thumb" area of the lower peninsula. Not all counties have added roads to the county highway system, though all approved it at the time it was adopted. Over time, some counties have stopped maintaining the signage on the roads they added to the county highway system due to lack of money. This has led many of the county highways to be poorly labeled. Due to the lack of maintained labels, it may not always be apparent that you're driving on a county highway. This doesn't mean they aren't still part of the county highway system, just that the signs are not being maintained well.

In general, rural routes should be set at a higher level than equivalent routes in built-up areas. Even though they're typically narrow, they still carry high-speed traffic, and are still used for medium- to long-distance routing.

Based on the standards set forth in the Wiki, the Primary Street type is only used for edit intra-city travel; any route used for inter-city travel should be a Minor Highway or higher. "Main Street" small towns, which typically sit along or at the intersection of inter-city routes, won't typically have any Primary Street class routes at all, below a certain size, perhaps unless they are accessed by small collector roads off a main route. I don't think that's very common with Southeast Michigan's grid system, though.

So basically, if a county highway connects towns, it should probably be a Minor Highway. If it's a smaller main road that only serves a town or possibly two towns in close proximity, Primary Street could do.

And since there are necessarily going to be sort of a lot of highways, making all US routes Major Highway is a good way to distinguish them.
