Strategic Overview
Purpose and Scope
The San'in Kinki Expressway (山陰近畿自動車道, San'in Kinki Jidōsha-dō) is designated as a planned expressway within Japan's national highway system. Its strategic objective is to create a vital transportation corridor, linking the San'in Expressway from the Tottori interchange with the Kyoto Jūkan Expressway. Upon its projected completion, the expressway is anticipated to span approximately 120 kilometers (75 miles), significantly enhancing regional connectivity and economic development.
Governance and Operation
This critical infrastructure project is jointly managed and operated by multiple entities, reflecting its regional importance. Key stakeholders include the West Nippon Expressway Company, the Kyoto Prefectural Road Corporation, and the Ministry of Land, Infrastructure, Transport and Tourism. This collaborative approach ensures comprehensive oversight and development across different administrative jurisdictions.
Expressway Numbering
The San'in Kinki Expressway is assigned the designation "E9". This numbering aligns it with the San'in Expressway and the Kyoto Jūkan Expressway, signifying its integral role within a larger, interconnected network of high-speed roads across Japan. This consistent numbering facilitates navigation and planning for travelers and logistics operators.
Route Description
An Incomplete Arterial
As of recent assessments, the San'in Kinki Expressway remains an incomplete route, characterized by several distinct, non-contiguous sections. These segments are planned to be connected over time through ongoing construction projects. The expressway is designed to run east to west, ultimately bridging the gap between Miyazu, Kyoto, and Tottori.
Key Connections
The expressway's planned termini are the Tottori Interchange, connecting to the San'in Expressway, and the Miyazu Amano Hanashi Interchange, linking to the Kyoto Jūkan Expressway. The route traverses the prefectures of Tottori and Hyōgo, with its easternmost section reaching into Kyoto Prefecture, underscoring its cross-regional significance.
Development History
Phased Construction
The designation of the San'in Kinki Expressway as a planned route dates back to December 16, 1994. Its development has been a gradual process, with various sections opening incrementally over the years:
- March 27, 2005: The initial section between Kasumi and Satsu interchanges was opened.
- November 24, 2008: The expressway was extended between Higashihama and Iigumi interchanges.
- December 12, 2010: An extension west from Kasumi Interchange to Amarube Interchange was completed.
- March 12, 2011: A separate eastern section opened between Yoza-Amanohashidate Interchange and Miyazu-Amanohashidate Interchange.
- March 22, 2014: The section between Fukube Interchange and Iwami Interchange became operational.
- March 26, 2016: The expressway was extended east from Iwami Interchange to Uratomi.
- October 30, 2016: The eastern section was further extended from Yoza-Amanohashidate Interchange to Kyōtango-Ōmiya Interchange.
- November 26, 2017: The expressway was extended west from Amarube Interchange to Shin'onsen-Hamasaka Interchange.
These phased openings reflect the complex logistical and financial undertaking of constructing such a significant piece of infrastructure.
