YIDO operates, manages and maintains several key pieces of infrastructure across the nation, including bridges, highways, ITS, airports, ports and railways.

Business Introduction

Il-suk Jung
Head of Infrastructure Division

The Korean government has recently shifted its focus on privately funded infrastructure projects.
Furthermore, required maintenance of aging infrastructure built in the 1970s and 1980s sparked the shift in demand for maintenance and safety management from development and construction.
Owing to these policy changes, YIDO has positioned itself as a major competitor in the infrastructure operations and management sector.
Our integrated development and operation services encompass the wide scope of domestic infrastructure goals, including transportation and tourism.
YIDO is set to be the largest privately funded road operator in Korea.
To continue this trend, we are securing future growth engines by continually optimizing our operations and seeking new privately funded ventures.
