Route description

The Mei-Nikan is a ring-shaped high-speed national expressway built around 10 kilometres (6.2 mi) from the city center of Nagoya. It is a 43.7 kilometres (27.2 mi) long second ring road for the city, the outer ring road is the incompleted 152.4 kilometres (94.7 mi) long Tōkai-Kanjō Expressway, and the inner ring route is the 10.3 kilometres (6.4 mi) long Nagoya Expressway Ring Route.^[3] Upon completion, the Mei-Nikan Expressway will have a total length of 55.9 kilometres (34.7 mi). The Mei-Nikan runs concurrent to Japan National Route 302, the only exception to this concurrency is the branch route that connects the ring road to the Tōmei Expressway.^[4]

The section between Hikiyama Interchange and Ōmori Interchange consists of tunnels that run underneath waterways; vehicles carrying dangerous goods are forbidden from travelling through these tunnels and must use alternate routes.^[5]

History

The first section of what would become the Mei-Nikan Expressway was opened on 23 March 1988 between Kiyosu-higashi Interchange and Nagoya-nishi Interchange as part of the Higashi-Meihan Expressway.^[1] The expressway was opened in phases since then as part of the Higashi-Meihan until 2011, when it was redesignated as the Mei-Nikan Expressway.^[6]

Future

Construction is underway to extend the expressway 12.2 kilometres (7.6 mi) south to the Isewangan Expressway southwest of Nagoya by 2020. Upon completion, this would complete the loop made around the city by the two expressways.^[4]
