The first section of the Nagoya Expressway network opened to traffic in 1979. As of 2008, 69.2 kilometres (43.0 mi) of the network has been completed.
The Ring Route at the center of Nagoya is one-way, flowing clockwise. Routes 1 through 6 extend radially from the Ring Route, with Route 2 bisecting the Ring Route. Route 4 is the only route still under construction. Routes 11 and 16 are extensions of Routes 1 and 6 respectively; a separate toll is required for these routes.
Nagoya Expressway faces competition from the expressways operated by Central Nippon Expressway Company in the greater Nagoya area. Discount policies on these expressways are much more significant than those on the Nagoya Expressway network, which leads to reduced revenue for the Nagoya Expressway and reduced efficiency of the entire road network in the region.
