The JÅban Expressway (å¸¸ç£è‡ªå‹•è»Šé“, JÅban JidÅsha-dÅ), abbreviated JÅban-dÅ (å¸¸ç£é“), is a national expressway in Japan. It is owned and operated by East Nippon Expressway Company.

Naming

JÅban is a kanji acronym consisting of two characters. Each character represents a former province of Japan that is passed through by the route: Hitachi Province (å¸¸é™¸å›½) representing present-day Ibaraki Prefecture and Iwaki Province (ç£åŸŽå›½) representing the eastern portion of present-day Fukushima Prefecture

The expressway carries the JÅban Expressway name from the origin at Misato Junction to Watari Interchange. From Watari Interchange to the expected terminus at Tomiya-kita Interchange, the JÅban Expressway name is currently an official designation only.^[2] The section from Watari Interchange to SendaikÅ-kita Interchange is the Sendai-TÅbu Road, the section from SendaikÅ-kita Interchange to Rifu Junction is the Sanriku Expressway (Senen Road), and the section from Rifu Junction to the terminus is the Sendai-Hokubu Road. It is unknown if the naming of these sections will be changed upon completion of the JÅban Expressway.

Overview

The expressway is an important route connecting the greater Tokyo area with Mito, the capital of Ibaraki Prefecture. Beyond Mito, the expressway follows a northerly route along the coast of the Pacific Ocean to the city of Iwaki in Fukushima Prefecture. Most of the route beyond Iwaki is incomplete; when completed the expressway will reach the greater Sendai area. The expressway will also supplement the TÅhoku Expressway as an access route between Tokyo and the TÅhoku region.

For most of its length the expressway parallels National Route 6 and the JÅban Line of East Japan Railway Company

The first section of the expressway was opened in 1981. The section from JÅban-Tomioka Interchange to Watari Interchange is under construction,^[3] and extensions and upgrades to the existing Sendai road network are also planned.^[4]
