Chiba Sotobō Toll Road

The Chiba Sotobō Toll Road (千葉外房有料道路 Chiba Sotobō Yūryōdōro) is a former tolled road in Chiba Prefecture, Japan until end of January 2023. The route is used to be operated by the Chiba Prefecture Road Authority. Chiba Prefecture Route 67 is designated along the whole highway. It was built to alleviate traffic along Chiba Prefecture Route 20, connecting southeastern Chiba Prefecture to Chiba and Tokyo further to the west. The toll road runs between the Ken-Ō Expressway and Chiba-Tōgane Road, paralleling Route 20 and JR East's Sotobō Line from Mobara to Chiba. The toll road, unlike most toll roads in Japan, was not given an expressway number under the Ministry of Land, Infrastructure, Transport and Tourism's "2016 Proposal for Realization of Expressway Numbering".[2]
