It is the most heavily travelled roadway operated by Central Nippon Expressway Company, with some sections used by more than 100,000 vehicles a day.

The route continues west into Shizuoka Prefecture, passing to the south of Mount Fuji and along the coastline of Suruga Bay, paralleling National Route 1 and the historic Tōkaidō highway before reaching the city of Shizuoka.

The expressway then heads northwest, passing to the east of the city of Nagoya and meeting the terminus of the Chūō Expressway before terminating at an interchange in the city of Komaki to the north of Nagoya.
