The Jōban highway ( Japanese 常 磐 自動 車道 , Jōban Jidōshadō ) is an important highway in Japan and crosses the Japanese main island of Honshū from Misato to Watari and meets the Sendai-Tōbu-Dōro here. Its course essentially follows that of National Road 6 .
The 300.4 km long highway is the ostjapanischen motorway operating company East Nippon Expressway Company (KK English. East Nippon Expressway Co., Ltd. , NEXCO ) operated and is known as "National mainline" ( Kokkandō , short for 国土開発幹線自動車道 , kokudo kaihatsu kansen jidōshadō ) classified.
history
The decision to build the line between Tokyo and Iwaki was made in 1966, for the connection to Sendai in 1987. Construction began in 1970, the first section of the Jōban highway between Kashiwa and Yatabe (in Tsukuba ) was opened in 1981.
Due to the exclusion zone with a radius of 20 km around the Fukushima nuclear power plant , which was set up due to the Fukushima nuclear disaster and was officially set up on April 22, 2011, the use of the almost 20 km long section from Hirono to Tomioka was only permitted with an official special permit . On February 22, 2014, the route was opened to traffic again. At the opening ceremony, the Minister of Transport, Akihiro Ōta , who was present, announced his intention to resume the expansion of disused construction sections. The completion of the section from Namie to Minamisoma, originally planned for 2011 , finally came about on December 6, 2014. The current radiation exposure is shown on three overhead displays. The Sōma - Yamamoto section was also opened.
The last 14.3 km long section Namie-Jobantomioka (north of Tomioka) was completed and opened by March 1, 2015. This means that the highway in Fukushima prefecture can be used continuously and without a permit. In this section, the radiation exposure is displayed at six measuring points; in February 2015 this measured about 5.5 µ Sv / h. According to an official statement, the dose for a person traveling in a vehicle at 70 km / h is 0.2 µSv, which corresponds to about one hundredth of a full-body computed tomography . In order to keep the radiation exposure low, shoulder and embankments were concreted in 15 cm thick in some places.
