Hitachinaka Road
The Hitachinaka Road is a 4-laned expressway-standard road in Hitachinaka, Ibaraki, Japan. The section from the origin to Hitachinaka Kaihin [Kōen Interchange] is a toll road operated by Ibaraki Prefecture Road Public Corporation, and the remaining section from Hitachinaka Kaihin Kōen Interchange to the terminus is a free road managed by Ibaraki Prefecture.
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 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."
