Route description

From its southern terminus with Momoishi Road, the Daini-Michinoku Toll Road travels north from Shimoda-Momoishi Interchange in Oirase. The speed limit for the toll road is 60 km/h. The road quickly enters an agricultural area after its start. Three kilometers from Shimoda-Momoishi Interchange the road meets its toll booth. There are two gates servicing traffic in each direction. A parking area is available for drivers. At the booth the road proceeds northwest. Approximately 3.6 kilometers from the booth the road meets Aomori Prefecture Route 10 at an interchange. Shortly after the interchange, the road gradually curves north. Along the gradual curve, the toll road continues on a ramp exiting to the left from the Kamikita Expressway. The Kamikita Expressway proceeds to continue northwest towards Aomori. The ramp carries the toll road on to its northern terminus at an at-grade junction with Aomori Prefecture Route 10 at the southern city limits of Misawa.^[5]

Future

The toll road is planned to be incorporated into a single expressway that extends north and west to connect with the Aomori Expressway and the northern terminus of the Tōhoku Expressway at the Aomori Interchange. This will be done by linking the Kamikita Expressway and Michinoku Toll Road to the Aomori Expressway.^[6] The thirty-year toll collection period for the use of the road was set to expire in March 2022, but as of March 2025 the tolls are still collected.^[7][4]

Junction list

The entire toll road is in Aomori Prefecture.
