This is a general topic thread for South Dakota roads and highways. I don't think one exists already.

Here is an article related to traffic conditions on Colorado Boulevard in Spearfish. This is the segment that parallels Interstate 90 and US 14-85 between Exit 14 (Business 90 and US 14A) and Exit 17 (US 85).

As due diligence in preparation for the 40-acre sports complex being built along with the 180-lot housing development currently under construction near Exit 17, city officials contracted with HDR, Inc. to complete a traffic impact study for the area to see what issues might need to be addressed as the sporting events center attracts more travelers to Spearfish.

The study focused on five intersection points around the development area – the Interstate – 90 on and off ramps at Exit 17; the intersection of Colorado Boulevard and U.S. Hwy. 85; the intersection of St. Onge Road and U.S. Hwy. 85; and the four-way intersection at Colorado Boulevard and Rainbow Road. The study also looked at three entry and exit points to the development area. ...

Two of the intersections would be operating at a service level of ‘F’ by 2022 if no improvements were made.

One of those intersections is the westbound ramp terminal at Exit 17; however, that deterioration won’t be caused by the development, so those improvements will be monitored and made by the South Dakota Department of Transportation (DOT). The other issue was identified at the intersection of Colorado Boulevard and Highway 85, which the study shows, will be impacted by the development.

Landslide repair is underway at South Dakota 36 near Custer State Park. The project will address current damage and help prevent more landslides in the future.

Yeah the problem with that area is when the city annexed out there they inherited the narrow no-shoulder Lawrence County-maintained service road (which is absolutely terrifying to ride a bike on, least on that stretch) and now they're trying to develop that area over what the county anticipated. I'm not sure what the DOT project on 85 is, but if they add stoplights to Exit 17 and the Colorado/St. Onge intersection that would solve a lot of problems.

South Dakota drivers are paying a deadly toll for disregarding the rules of the road.

Drivers who are speeding, not wearing seat belts, and/or having consumed alcohol and other intoxicants, are dying at a much higher rate than in recent years, according to a report from the state Department of Public Safety.

Because of that bad behavior behind the wheel, more died on South Dakota highways and roads in 2020 than 2019, with 141 people killed in 132 fatal crashes in 2020, according to the DPS. There was a 38% increase in fatalities, as 102 people died on South Dakota highways and roads in 2019.

Presuming you're being sarcastic in saying "surprising".  Doesn't surprise me at all.  It's been well-documented in much of the nation that the reduction in traffic over the past year due to COVID restrictions has resulted in higher speeds, more crashes, and more fatalities.

What is with the I-90 Business Loop being very well signed through Rapid City and then through Black Hawk but no BL 90 sign to be found exiting I-90 EB to the BL90?

Since I missed this post a few months ago: the surprising part isn't that it increased, but that a state that didn't shut down as much as other states saw the largest increase.

The portion from Black Hawk to W. Chicago is unsigned SD 231, DOT signs it as BL 90 because that makes more sense. After that, it's city maintained, and a lot of the signage might be legacy signage since E. North St. was recently reconstructed.

Tourists? Since we didn't really shut down at all (nothing closed in Spearfish except where national chains pushed policies) there've been TONS of out-of-staters going through.

People want to live here because we're awesome! Probably a combination of low taxes, pretty scenery, and reasonable access to amenities in Rapid without having to live in Rapid.

Blizzard closure point.  Many cities out west have these at the edge of town so that you have to return to town instead of traveling into a dangerous situation.

At the location you have, there is a gate on I-90 WB at Exit 395.  They are preceded by these signs: https://goo.gl/maps/E69T87mgM1pyrFsx9

These are all over the place as you go across i-90.  Wisconsin has them on a lot of the entrance ramps to keep traffic off the interstate for accidents or blizzards.  Seeing them on the highway was unique.  It's a good thing since there are LONG stretches with no exits.  Bad place to get stuck in a blizzard.

Florida and Georgia have them as well for hurricane traffic redirection.

Referring to an earlier post, I have been reading about the higher accident rates during the pandemic in many states and it has really baffled the researchers.

The simple answer is lack of traffic removes impediments but I think that is too broad a stroke.  If anyone has a link to more detailed research data, I would love to read more on it.

2020 was also a record year for RV travel in the US. RV sales nationally have been at record highs. Would be interested to know if that played a role in any of the statistics.

Why does the design take 5 years? Seems like it could be done in 1 or 2. Do they not have the funding to build it right away?

The final IMJR for the I-90 Exit 59 DDI project, which started in early 2021 and is currently ongoing, was approved in 2016. It seems they like to procrastinate a bit with some of these larger projects.

Interesting, seems kind of bass ackwards to me. I would think they could save money on inflation if they do it sooner.

State government in SD works at its own pace, unless the issue becomes a political football. For instance, there's a bridge out west of Spearfish on a wildlife area that partially washed out (safe for pedestrians and ATVs but not cars) in ~2012 or so. Despite calls to fix the bridge, Game Fish & Parks did nothing until they got called out at a public meeting about a proposed state park (the comment was something along the lines of "Why should we trust GF&P to manage this park when they can't fix a bridge in 5 years?"). The bridge was fixed within the next month.

If you rewind down the road a bit, you'll notice that the other car started his pass before the passing zone even started. I get that it's a two lane road but do you really have to be that impatient?

Likely that guy's from Philip or the surrounding environs, road rules tend to get a bit soft out in the sticks if you live out there (e.g. the stop signs by my folks' house are more like yield signs since traffic is non-existent, yes we should do better).
