The Aomori Expressway (青森自動車道, Aomori Jidōsha-dō) is a two-lane national expressway in Aomori, Aomori Prefecture, Japan. It is owned and operated by East Nippon Expressway Company and is signed E4A as a direct extension of the Tōhoku Expressway.[3]

Route description

Aomori IC near the north end of the Tōhoku Expressway and the western terminus of the Aomori Expressway.
The Inayama Tunnel west of Aomori-higashi IC.

The expressway is officially referred to as the Tōhoku Jūkan Expressway Hachinohe Route.[4]

The expressway serves as an extension to the Tōhoku Expressway (which terminates at Aomori Interchange) and runs through southern areas of the city of Aomori.[5] From Aomori Interchange, it runs east, crossing under the tracks of the Tōhoku Shinkansen. Soon after the expressway meets National Route 7, which serves for several kilometers from here as a frontage road to the expressway. Eventually, the two roads have are linked by the Aomori-chūō Interchange where tolls are collected for the entire expressway, including any tolls accrued from travelling from the Tōhoku Expressway. The expressway continues east and splits from National Route 7 before it comes to its end at Aomori-higashi Interchange near the western terminus of the Michinoku Toll Road.

The speed limit is 70 km/h for the entire route.

History

Construction on Aomori Expressway began in 1999 and was opened to traffic on September 28, 2003. The completion of the expressway reduced travel times from the Tōhoku Expressway to Central Aomori by 11 minutes and reduced congestion along the Aomori West Bypass.[6]

Future

Though the Aomori Expressway terminates at Aomori-higashi Interchange, it is planned to eventually connect with the northern terminus of the Hachinohe Expressway in the town of Oirase via a series of toll roads.

Junction list

The entire expressway is in Aomori Prefecture. Also, it is to be noted that the expressway is a direct extension of the Tōhoku Expressway. Therefore, the distance and exit numbers continue from the sequence of the Tōhoku Expressway.
