The is a national expressway in the Shikoku region of Japan. The expressway is numbered E32 between Kawanoe Junction and Kōchi Interchange and E56 between Kōchi and Kuroshio-Ōgata Interchanges under the MLIT's "2016 Proposal for Realization of Expressway Numbering.
Overview The first section of the expressway was opened to traffic in 1992. As of March 2008, the expressway is incomplete in many areas. The next section is scheduled to open in 2009 (Susaki-Higashi Interchange to Shinshōgawa-bashi East Interchange). After this, all future sections will be built according to the New Direct Control System, whereby the burden for construction costs will be shared by the national and local governments and no tolls will be collected. Currently the section between Susaki-Higashi Interchange and Kuroshio-Ōgata Interchange operates according to this principle.
The expressway is 4 lanes from Kawanoe Junction to Kōchi Interchange, and 2 lanes for all remaining sections.
