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.

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).

--- Quote ---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 wont 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.

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.

So what is with all of the sudden growth out in Lawrence County anyway?

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.
