When was the last time either of the Dakotas designated a new highway?

[TCN7JM]

For all I can remember, neither of the Dakotas have designated anything in what seems like ages. Anyone else have a clue?

SD 19 was extended south in 2001.

When was the most recent new piece of ND/SD 1804 or 1806 opened?

what about all those 4xx series routes in southwest South Dakota?  weren't some of those fairly recent designations?

[TCN7JM]

Highways 1804 and 1806 seem to be much older than I thought they were. They show up on what doesn't look very different from their current alignments on my 1976 North Dakota map, and my 1987 South Dakota map has them, too (the next earliest one I have is from all the way back in 1968, and they didn't exist then).

Speaking of that 1987 map, SD 391, 407, and 471 all existed when that map was printed.

Didn't SD 38 east of Sioux Falls to the Iowa border and IA 9 become SD 42 some time in the 1980's or 1990's?  I was a kid then, but when I would go to my grandma's in SW Minnesota, we'd go to Sioux Falls, and I vaguely recall somewhere along the way SD 38 became SD 42.

As for North Dakota, wasn't ND 200 a 1970's creation, along with the rest of the 200's?

I wouldn't be surprised if something like that happened, but that isn't really a new designation, per se.

As for ND 200, I'll have to check my maps sometime soon. I have the one from 1976 and a few from the 1980s, but I'm not near them at the moment.

[TCN7JM]

Okay, it seems ND 200 existed on the 1976 map, so that's too old.

Side note, the 1987 map has SD 38 stretching to the Iowa state line where SD 42 is now, so you're right there.

SD 79 is signed all the way down to the Nebraska line now, and I don't think that happened until 2009 or so

Yes, that's new.  Was not that way in 2005.

Also, the recent (2 months ago) AASHTO route numbering committee meeting (covered in another thread) approved a new alignment of US 85 outside Williston, ND.

[TCN7JM]

So from what I'm seeing/hearing here, there have been a lot of recent extensions, but there hasn't been a new designation since the 70s or earlier. That's no fun.

[SD Mapman]

I know, right?... However they signed Highway 249 near Fort Thompson the last time I was there (9/20). I don't remember that ever.

[agentsteel53]

MSR-200 is 1968, if I recall correctly.

as for SD-42 - I seem to recall Jeff Morrison's Iowa Route Ends page showing a Mount Rushmore style (1961-72 or so) SD-42 shield just inside Iowa.  it may have been a different number; I just plain don't remember.

never mind, I found it.  it is SD-48, at the junction of IA-12 and IA-403.



that shield was gone by the time I tried to find it in October, 2009.  there is one Rushmore shield left as far as I know... it's a 79.

[NE2]

Holy hell. That's a real design. I thought it was a joke made up for http://www.northernplainshighways.org/sdakota/ .

[SD Mapman]

Blasted Iowa DOT!

[Brandon]

Yes, and there's more in the shield gallery.

[Molandfreak]

It's a very bad design at that. Too cluttered, you can't tell what it is unless you look closely. I'm glad they got rid of it.

Out of curiosity, where is it?

[agentsteel53]

in one of the towns on the old alignment bypassed by the expressway.  Fairburn, IIRC.  it's attached to the same post as a yield sign; back to back.

I found it in the middle of the night; I need a daylight photo.

That looks very amenable to next year's planned travels. If you verify its existence, please keep me/us updated.

[SD Mapman]

Huh, never knew that... but back to the original topic (kinda), the official list of SD highways is found here http://legis.state.sd.us/statutes/DisplayStatute.aspx?Type=Statute&Statute=31-4

[M86]

Well, hopefully SD 100 will be the newbie soon, by 2018.

Typical long wait for state projects...

And yet SDDOT, in 2015, is planning on spending $36-40 million dollars on two new SPUIs at locations (I-190 Exit 1 and I-90 Exit 14) in which current traffic counts come nowhere close to justifying SPUIs (and likely never will, in the case of I-190 Exit 1). In both instances, the commenting public was presented with options that were significantly deemed acceptable by them that would have cost $5 for each interchange. But some folks in SDDOT can't bear the thought of making I-190 a surface street (current traffic counts easily justify this), and some folks have this weird attitude against roundabouts in Spearfish.

[TCN7JM]

Well that one might just be cluttered because there are two numbers on top of each other. 

As for SD 100, there is some progress being made, but it's slow as all hell. SD 11 is still closed here from 26th Street to 57th Street (I think that's about two miles), as it has been for, like, all summer, and there's still some gravel road north of the city they have to pave.
