Guess I missed the "Avoid Freeway" part.

I suppose it's about due time we come to a concensus about speed limits on our secondary hwy's traveling through counties on back roads like this. We know that these can change due to seasonal conditions. Although during the summer I'm doing about 55 :lol:
I'm thinking 35mph

You could say that. I guess it's like adding a SL to a ramp. So set them to the SL of said road. Then let Waze worry about the disclaimer. :lol:

Edit: On top of said SL occasionally they will post a new SL further down the road once it changes from pavement to gravel. SV usually ends at the pavement too.

Sure. By the way, at some point coming down the hill towards Livingston the SL bumps to 80mph. I haven't nailed down the change point yet, but the segments attached to this exit should be safe to set this high.

What are the guidelines for exit speed limits? If the ramps are short they may have signs for 25 or 15 mph to show you need to quickly decelerate to about this speed to make a sharp curve or short stop. The normal-sized ramps seem to just be "stop ahead" mph. Around 40 - 45 seems reasonable, or do we just want to follow the signage?

Are we going with the "Truck" speed limit (65)? Because the default freeway speed limit is 75, and it's 80 east of Livingston.

That's what I thought. I ask because it's set to 65 around Bozeman and it should be 75.

It goes up to 80 coming down the hill into Livingston from the west. I still haven't nailed down where (maybe this weekend.) I've confirmed it's 80 up to Park City. I wouldn't be surprised if it was 80 all the way to North Dakota, maybe slowing down for Billings.

There's also a bit between Bozeman and Three Forks that's 80, but I'm not sure exactly where.

This Missoulian article has some detail for western Montana. You might be able to correlate mile marker references with some of the state maps, but I guess east-of-the-divide doesn't matter to the hill people.

With fuel as cheap as it is, I might have take a few recognisance road trips.

I think that's only for non-restricted-access highways. The posted limit is 75 between exits 305 and 313.

I was surprised how many curves were still ahead of the change to 80 going down to Livingston. I thought they'd at least wait until the bottom of the hill. And it didn't slow down for any populated areas I passed through before I turned around in Park City.

Not for a long ways. I'll drop a UR next to the sign.
