That section had no predecessor road at all. +- **穂高トンネル is 1,991 m long and was built in 1991.** The two numbers are identical + and the national register's own column order makes them easy to confuse. +- **モトツシェルター (62 m, 1990) and モトツ橋 (62 m, 1988)** — same length, same name, + two years apart. +- **福山第1ゲート 79.81 km, 福山第2ゲート 79.86 km** — the closure gates, 50 m apart. +- **21 km of nothing** between 穂別福山 (80.01) and 日高 (100.90): no named facility, + no PoI, no settlement within 2 km. That is ニニウ and the 樹海. +- The 滝下/滝の上 cluster carries the の/ノ split: 滝の上発電所 and 滝の上公園 against + 滝ノ上神社 and the district 滝ノ上. The register writes 滝の上こ線橋. +- **十三哩橋** in the register, **十三里橋** on the sign, **とみさと** on the map. + 13 miles from 追分, via 里, into a hamlet name. +- 夕張市街 is **17 km** from 紅葉山交差点. That is how far the road misses the town by. +- JR石勝線 runs alongside here under **many スノーシェッド**. R274 has none. +- 道道1065号夕張厚真線 is severed at the 夕張/厚真 boundary and the plan to finish it + has been cancelled. +- Overhead at 紅葉山: **夕張のぞみ橋, 夕張きぼう橋, 夕張みらい橋** — three E38 bridges + named Hope, Wish and Future crossing a road whose own bridges carry river names. + +### Flags + +- 右左府発電所 is not in OpenStreetMap; only 右左府変電所 and the line 右左府線. + Coordinates need manual confirmation. +- 交差点 names have no open database — OSM has 7 named nodes on all 388 km. Junction + names in scope come from ja.wikipedia and route01 only. +- 唐沢橋 and 福本沢川橋 are in 日高町 but their position relative to 右左府 is unconfirmed. +- Distances are not official KP. One kilopost read on Street View would fix the offset. +- A 史跡 at 103.41 km appears in OSM with the name `79616` — an import artefact, not a name.
