It is owned and operated primarily by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), but has a section maintained by the East Nippon Expressway Company.

Near this junction, drivers pass through a toll booth that collects fees based on the distance traveled on the Hachinohe Expressway.

Upon emerging from this tunnel, named Korekawa, the expressway curves back to the east.

This section of the expressway begins at an interchange with National Route 45 on the northern edge of Kuji.

The route crosses over the Hachinohe Line before meeting its southern terminus at Kuji Interchange.
