Aomori Belt Highway

The Aomori Belt Highway primarily serves as a bypass of the central part of the city of Aomori. For planning purposes the city considers the area outside of the highway to be the "outer" part of the city.[1] It starts at a junction with its parent route, the main line of National Route 7, near the Sannai-Maruyama archaeological site in southwestern Aomori city. From there, it travels southeast towards Aomori Interchange, a junction between the Aomori Belt Highway and the northern terminus of the Tōhoku Expressway. Curving to the south and then east, it passes by the Sannai-Maruyama Site and the Aomori Museum of Art and then begins paralleling the Aomori Expressway. The Aomori Belt Highway serves as a frontage road for the expressway for the next several kilometers with access to the limited-access road at Aomori-chūō Interchange. While heading east, the highway intersects several roads that lead to and from the center of Aomori, including National Route 103 and Aomori Prefecture Route 120. After the intersection with National Route 103, the highway begins slowly curving to the northeast and eventually to the north. When the belt highway curves to the north, the Aomori Expressway stops paralleling the highway, continuing northeast. About 2 kilometers (1 mi) north of this split the Aomori Belt Highway terminates at an intersection with National Route 4.[2]

The Aomori Belt Highway was initially planned as one of three highways that passed through the city of Aomori from west to east in 1964.[3] It was originally opened as a two-lane road in 2002, but was mostly expanded to a four-lane highway by 2009 serving as a frontage road to the Aomori Expressway.[4] The interchange connecting it to the Aomori Expressway was completed on 28 September 2003 at a cost of 79.5 billion Japanese yen.[5]

The entire highway is located within Aomori Prefecture. All junctions listed are at-grade intersections unless noted otherwise.
