国道254号 Bypassルート | 東京から長野へバイパス道でゆくR254全線 | 起点（東京都文京区）→ 終点（長野県松本市）約228km | 車載動画 | GoPro11

Route 254 runs from Bunkyō Ward, Tōkyō, to Matsumoto City, Nagano Prefecture, via Toshima, Itabashi, and Nerima Wards in Tōkyō, Wakō, Asaka, Niiza, Fujimi, and Kawagoe Cities in Saitama Prefecture, Fujioka, Takasaki, and Tomioka in Gunma Prefecture, and Saku and Ueda Cities in Nagano Prefecture. The road conditions are varied, ranging from a main street in the center of Tokyo to a narrow road through mountainous areas and a 2,500-meter-long tunnel through Mount Misa in Nagano Prefecture. The Misayama Tunnel Toll Road and the Matsumoto Tunnel Toll Road, which were toll-free for a long time, became free of charge in September 2020. This video was recorded along routes that run as far as possible on bypasses that have already been opened, including those that are partially in service. *old road route -    • 国道254号 旧道ルート | R254のバイパスを避け東京から長野へ | 起点（東京...   Departure : Route 254 start point (Hongo 3 intersection = Route 17 intersection) - Hongō, Bunkyō Ward, Tōkyō Arrival : Route 254 end point (Hiraseguchi intersection = Route 19 intersection, Route 147 end point) - Shimauchi, Matsumoto City, Nagano Prefecture Date : Late December, 2022 Distance : approx. 228 km (measured by Google Maps) Route map: https://www.google.com/maps/d/u/0/emb... 00:00:00 Opening 00:02:27 Route 254 start point (Hongō 3 intersection = Route 17 intersection) - Hongō, Bunkyō Ward, Tōkyō 00:09:30 Higashi Ikebukuro, Toshima Ward 00:13:38 Tokyo Metropolitan Road 317 Kanjō-Rokugō Line, Yamate-Dōri Ave. Intersection - Kumano-chō, Itabashi Ward 00:16:57 Tokyo Metropolitan Road 318 Kanjō-Nanagō Line, Kannana-Dōri Ave. Intersection - Higashiyama-chō, Itabashi Ward 00:20:32 Tokyo Metropolitan Road 311, kanjō-Hachigō Line, Kanpachi-Dōri Ave. Intersection - Kita-machi, Nerima Ward 00:22:10 Route 17 Shin-Ōmiya Bypass Intersection - Kita-machi, Nerima Ward 00:27:36 Border: Nerima Ward, Tōkyō → Wakō City, Saitama Prefecture 00:43:46 ↖Route 254/463 Urawa-Tokorozawa Bypass / ↑Route 254 Old Road - Nakano, Niiza City 00:45:02 Miyoshi-machi, Iruma County 00:46:45 Harigaya, Fujimi City 00:50:51 ← Route 254 Fujimi-Kawagoe Bypass / ↑Route 463 - Shimonanbata, Fujimi City 00:56:36 Komabayashi, Fujimino City 01:07:15 Route 16 intersection - Kosenba, Kawagoe City 01:15:19 Ochiai Bridge (Iruma River) - Fukuda, Kawagoe City 01:20:26 C4 KEN-Ō EXPWY, Kawajima IC - Kawajima-machi, Hiki County 01:24:09 Furukōri, Higashimatsuyama City 01:30:03 Route 407 intersection - Shimonomoto, Higashimatsuyama City 01:34:14 E17 KAN-ETSU EXPWY, Higashimatsuyama IC - Ishibashi, Higashimatsuyama City 01:42:16 Ranzan-machi, Hiki County 01:46:23 ← Route 254 old road | ↑Route 254 Ogawa bypass - Shiga, Ranzan-machi, Hiki County 01:57:04 ← Route 254 Old road - Tomida, Yorii-machi, Ōsato County 02:04:58 Route 140 Overlap - Sakurazawa, Yorii-machi, Ōsato County 02:06:34 Route 140 Overlap ends - Sakurazawa, Yorii-machi, Ōsato County 02:10:27 Misato-machi, Kodama County 02:18:00 Akagi Nyūgyō Company Limited, Honjō Senbon Sakura "5S" Factory - Kodama, Kodama-cho, Honjō City 02:22:31 Route 462 intersection - Yoshidabayashi, Kodama-chō, Honjō City 02:28:57 Kamisato-machi, Kodama County 02:30:45 Border: Kamisato-machi, Kodama County, Saitama Prefecture → Fujioka City, Gunma Prefecture 02:40:33 Ogushi, Yoshii-machi, Takasaki City 02:46:34 ↑Route 254 old road | → To Route 254 bypass Yoshiikita dōri - Yoshiikawa, Yoshii-machi, Takasaki City 02:53:28 Kanra-machi, Kanra County 02:55:16 Route 254 Tomioka Bypass - Fukushima, Kanra-machi, Kanra County 02:57:34 Tajino, Tomioka City 03:06:46 ← Route 254 Old Road - Ichinomiya, Tomioka City 03:14:34 E18 JŌSHIN-ETSU EXPWY, Shimonita IC - Mayama, Shimonita-machi, Kanra County 03:17:02 Roadside Station Shimonita - Mayama, Shimonita-machi, Kanra County 03:34:49 Mogi Drive-in - Minaminomaki, Shimonita-machi, Kanra County 03:49:31 Border: Shimonita-machi, Kanra County, Gunma Pref. → Uchiyama, Saku City, Nagano Pref. 04:05:25 Saku Ōhashi Bridge (Chikuma River) - Saku City 04:08:26 Route 142 Overlap / Route 141 intersection - Atobe, Saku City 04:10:25 Roadside Station Healthy Terrace Saku Minami - Tomono, Saku City 04:15:11 Roadside Station Hot Park Asashina - Kou, Saku City 04:27:49 Roadside Station Megami no Sato Tateshina - Motai, Tateshina-machi, Kitasaku County 04:30:55 Route 142 Overlap end - Yamabe, Tateshina-machi, Kitasaku County 04:34:19 Furumachi, Nagawa-machi, Chiisagata County 04:38:55 Route 152 Overlap - Furumachi, Nagawa-machi, Chiisagata County 04:41:20 Takeshi River - Takeshioki, Ueda City 04:43:34 Route 152 Overlap end - Koshigoe, Ueda City 04:57:20 Nagano Prefectural Road 12 Maruko-Shinshū-Shin Line intersection - Kakeyu Onsen, Ueda City 05:03:27 Misayama Tunnel Toll Road Toll Station Site - Kakeyu Onsen, Ueda City 05:17:45 Matsumoto Tunnel, Length 2447m - Okadaibuka, Matsumoto City 05:20:39 Matsumoto Tunnel Toll Road Toll Station Site - Shimauchi, Matsumoto City 05:22:16 Route 254 End
