• 2-7 assigned to major corridors:
  • 2 ← 50 (part), 421
  • 3 ← 37 (part), 827
  • 4 ← many many routes
  • 5 ← 39 (part), 41, 835
  • 6 ← 18, 19 (also a conflicting number)
  • 7 ← 37 (part), 54 (part), 822, 826
• 8-14 assigned to conflicting numbers:
  • 8 ← 23
  • 9 ← 25
  • 12 ← 17 (the parts that didn't become new major corridor 4 or extended existing 42)
  • 14 ← 29, 38 (part), 600 (part)
• major single-district routes or portions of routes that mostly became others - roughly clustered, but 44 and 52-54 don't fit well:
  • 18 ← 800
  • 20 ← 316, 702
  • 22 ← 39 (part)
  • 24 ← 43 (part), 207, 306 (part), 308, 325 - why didn't this remain 43?
  • 26 ← 306 (part), 307, 327
  • 31 ← 510, 542, 547
  • 32 ← 509, 538 - how is this a major route?
  • 33 ← 508
  • 34 ← 401
  • 36 ← 408, 409, 435
  • 37 ← 407
  • 38 ← 406
  • 39 ← 304 (part)
  • 40 ← 20 - why?
  • 41 ← 301 (part)
  • 43 ← 215, 320
  • 44 ← 419 - this doesn't fit the rough clustering
  • 46 ← 12 (part)
  • 47 ← 434
  • 52 ← 505
  • 53 ← 506
  • 54 ← 39 (part), 50 (part)
• Numbering by district began with 59. The entire lengths of two two-digit routes were renumbered into this system:
  • 94 ← 58
  • 97 ← 47

1940

• matched Kentucky:
  • 4 ← 84
    • 4 already free (had become US 33)
  • 66 ← 65, 70 (part)
    • 66 free from becoming 70
  • 160 ← 67
    • 160 → 271
      • 271 free from becoming 84

• matched North Carolina:
  • 16 ← 88, 92 (NC extended 16 over, replacing their 681)
    • 16 → 27
      • 27 free from becoming 170
  • 32 ← 10 (part)
    • 32 → 88
      • 88 free from becoming 16
  • 37 ← 53
    • 37 → 106
      • 106 free from becoming 87
  • 46 ← 34
    • 46 → 92
      • 92 free from becoming 16
  • 87 ← 106 (NC extended 87 over, replacing part of their 54)
    • 87 → 78
      • 78 free from becoming 91
  • 89 ← 96
    • 89 already free (had become secondary)
  • 96 ← 49 (part) (both states chose a single new number, NC replacing 562)
    • 96 free from becoming 89
  • 170 ← 27 (NC extended 170 over, replacing part of their 34)
    • 170 → 238
      • 238 free from becoming 9
  • 258 ← 158 (NC swapped US 258 and US 158)
    • 258 → 158

• matched Tennessee:
  • 70 ← 66
    • 70 → 64 (existing), 66 (part)
      • 64's rerouting left behind a piece which became 65
        • 65 free from becoming 66
  • 75 ← 77 (was supposed to match, but TN never changed 44 to 75)
    • 75 → 77
  • 91 ← 78, 81
    • 91 → 81
      • 81 also replaced part of US 58, which was realigned to replace 305

• matched West Virginia:
  • 9 ← 238
    • 9 → 120, 123
      • 120 → 245 (why was 120 brought into this? why not simply use 245 for part of 9?)
        • 245 → 234 (existing) (this change made as part of extending 17 to MD, which replaced part of 234)
      • 123 already free (had become facility route 320)??
  • 39 ← 501 (WV extended 39 over, replacing their 43)
    • 39 → 47 (existing)
  • 59 ← 261
    • 59 free from becoming 83
  • 83 ← 59
    • 83 → 67
      • 67 free from becoming 160
  • 84 ← 271
    • 84 free from becoming 4
  • 259 (existing) ← 275 (matched WV 58, which was renumbered 259 to match the other piece of VA 259)
  • 522 ← 3 (part), 7 (part), 49 (part) (proposed extension of US 522 from MD through WV; not sure if WV renumbered its side simultaneously)
    • 3 (orphaned part) → 261
      • 261 free from becoming 59

34, 53, 275, and 305 were newly free.

only the new nonmatching numbers (other than simple swaps):

• 27 16: lowest number chosen for long route
• 34
• 53
• 65 64 (part)
• 67 83
• 78 87
• 88 32
• 92 46 (part)
• 96: new number chosen by both states to match
• 106 37
• 120/123 9
• 238 170
• 245 120
• 261 3 (part)
• 271 160
• 275
• 305

I don't see any real pattern here.
