"[1] As of February 2019, the expressway exists as two separate sections that are linked by the Izu Chuodo and Shuzenji Road.

Shuzenji Road is officially a branch line of the Izu-Jūkan Expressway while Izu Chuodo is not.

When completed the main line of the expressway will bypass the toll roads, running to the east of them.

The southern section of the expressway begins at a junction with the Shuzenji Road in the northern part of the city of Izu and travels south, parallel to Japan National Route 136.

Since then it has been expanded in stages, with the most recent expansion being a 5.1-kilometer-long (3.2 mi) section opened on 26 January 2019 between Ōdai and Tsukigase interchanges.
