Just thought I let everyone know that there is a section of US Hwy 212 in South Dakota that you might want to avoid. It is between Redfield and Faulkton SD. This section in packed gravel and dirt. The actual length of this section of "road" is 26 miles west of Redfield to the western edge of Redfield. There is no posted detour but google maps does show heading south on US Hwy 281 to SD 26 west and then going north on SD 45. Unfortunately I did take that route so I can attest to how it is, but I can tell you that the section of 212 wasnt fun at all. After getting over it and stopping in Faulkton, a local said it has been that way for a few years now with no completion date stated. I do know there was no construction equipment to be seen anywhere there.
The rest of US 212 was a nice drive and well worth the ride if you are either heading out to the Black Hills or back from there.
Just want to let you know in case you are planning on that route.
