The road is officially designated as Ibaraki Prefecture Route 57, however it is functionally an extension of the Kita-Kantō Expressway and Higashi-Mito Road. As such it is classified as a road for motor vehicles only (自動車専用道路, Jidōsha Senyō Dōro) (motor vehicles must have a displacement of at least 125 cc) with the same design standard as other national expressways and is also signed E50 in conjunction with those routes under the Ministry of Land, Infrastructure, Transport and Tourism's "2016 Proposal for Realization of Expressway Numbering."
