National Route 42 (国道42号, Kokudō yonjūni-gō), also called Kumano Kaidō or Tropical Route is a national highway connecting Hamamatsu, Shizuoka and Wakayama, Wakayama in Japan. Part of the route requires crossing Ise Bay on the Ise-wan Ferry.[2][3] It is the 8th longest national highway in Japan.

Route data

The total length on the main road is 487.2km(307.2 miles). However, by factoring in the overlapped section (33.4km/20.8 miles) and the sea crossing(19.8km/12.3 miles)the total distance becomes 540.3km(335.7miles).[4] At the origin Hamamatsu, the route starts overlapped with Route 1 and, is a junction to route 257 and 300. The route passes though the cities of Tahara, Toba, Ise, Matsusaka, Owase, Kumano, Shingū, Tanabe, and Gobō. At the terminus Wakayama, there is a junction with national route 24 and 26.

History

Route 42 was originally designated in January 1945 as a section of Route 41 (the Kumano Highway), which ran to Tokyo. This ran concurrent with Route 1 (now Route 1/Route 23). On 18 May 1953 Route 41 was classified as a Class 2 highway and redesignated as Route 170, which was later redesignated as Route 42 when the route was promoted to a Class 1 highway. On 1 April 1965, the classification of Class 1 and Class 2 was discontinued, redesignating it as General National Route 42.

On 1 April 1993, the highway was changed by removing the section of Tsu-Matsusaka and adding the Hamamatsu - Matsusaka. This was part of the plan to connect the Atsumi Peninsula, though the Kii Peninsula, Shikoku, Kyushu and terminating at Okinawa.[5] This plan is called the Japan Sea National Land Axis Plan.[6]
