Hachinohe-Kuji Expressway


The Hachinohe-Kuji Expressway is an incompleted expressway in the southeastern part of Aomori Prefecture and the coastal area of Iwate Prefecture in northern Japan. It is owned and operated primarily by the Ministry of Land, Infrastructure, Transport and Tourism, but has a section maintained by the East Nippon Expressway Company. The route is signed as an auxiliary route of National Route 45 as well E45 under MLIT's "2016 Proposal for Realization of Expressway Numbering."

Route description

As of June 2020, the expressway consists of two sections, one that bypasses the central part of Hachinohe, Aomori and the other travels north from the central part of Kuji, Iwate.

Hachinohe section

The northern terminus of the expressway is at Hachinohe Junction, where the route meets the branch route of the Hachinohe Expressway. Near this junction, drivers pass through a toll booth that collects fees based on the distance traveled on the Hachinohe Expressway. From this point, tolls are not incurred for driving on the Hachinohe-Kuji Expressway. Just beyond the toll booth the expressway crosses over the main line of the Hachinohe Expressway. There is no direct access from the Hachinohe-Kuji expressway to the northern terminus of the main line of the Hachinohe Expressway at Hachinohe Interchange. The Hachinohe-Kuji Expressway curves northeast, tunneling below Japan National Route 340. Upon emerging from this tunnel, named Korekawa, the expressway curves back to the east. The route then crosses the Niida River and immediately after has a junction with Aomori Prefecture Route 11. After this, the expressway continues gentling winding in generally in an easterly direction. It then meets Japan National Route 45 at a junction. Curving to the southeast, the two routes parallel one another with Route 45 only a few hundred meters to the west of the expressway. The expressway has one more junction that provides access to scenic spots along the Tanesashi Coast. After this junction the expressway meets Route 45 once more at Hashikami Interchange. This point of is the southern terminus of this section of the expressway.

Kuji section

This section of the expressway begins at an interchange with National Route 45 on the northern edge of Kuji. The entirety of the route closely parallels National Route 45 and later also National Route 395 as it travels south towards the center of Kuji. The expressway is further inland than National Route 395, tunneling through hills to bypass the built-up areas surrounding the parallel route. The route crosses over the Hachinohe Line before meeting its southern terminus at Kuji Interchange. This is also the southern terminus of the expressway.

History

The Hachinihe-Kuji Expressway has been constructed in several stages. The first one to open in 1993, is the section between Kuji and Kuji-kita interchanges in Kuji. The other sections in Aomori Prefecture were opened between 2013 and 2014. A second section in Kuji opened on 1 March 2020.
