SD: Broken Concurrency and Missing Graph Connection

[cockroachking]

I-90, US14, US16TrkRap, and SD79 have a broken concurrency between Exits 58 and 61. I-90 and US14 remain concurrent with each other, while US16TrkRap and SD79 remain concurrent with each other. However, there are two separate route paths due to mismatching point locations at Exits 59, 60, and 61. US16TrkRap and SD79 should be using the coordinates for the I-90 and US14 points in all three cases.

Also, I-90BLRap is missing its graph connection with these routes at Exit 60, since that point has a third set of coordinates for the same interchange...

Since Rapid came up:

I-90BLRap: CamSt, EastBlvd_N, US16, WestBlvd, MerRd, PeaPinRd need recentering (last two affect SD 231 as well); MainSt -> MainSt_W, ChiSt -> SD231_S

US16Trk/SD 79: the shaping point (think it's +X05 on US16Trk) on the Southeast Connector portion should move to Minnesota St since there's development there now

SD445: would recommend adding a point at Universal Drive (yes, I know it's close to Exit 55) to link to the corresponding point on the business loop. That's just what I would do, not essential.

For the record, SD 231 and SD 445 are not signed in the field. I've advocated for retaining them as:

Signage will show up for road construction detours.

They are not shown any differently than signed highways on the official state highway map: https://dot.sd.gov/media/fdf81efe/SDmap2023-high.pdf
