The host of the 2015 World Road Congress Seoul, 2017 FIFA U-20 World Cup, and 2018 PyeongChang Winter Olympics, South Korea is situated on the Korean Peninsula, at the eastern end of the Asian Continent.
As a peninsula, South Korea’s geography is characterized by seas bordering the country’s three sides, and the southwestern area in particular has a large number of islands and scores of gulfs and capes as the world’s representative rias coast.
In response to these geographical features of the nation, various efforts to improve the transportation conditions began in 1973 with the construction of Namhae Bridge. Afterwards, South Korea demonstrated the world’s leading capability to construct special bridges by building Yi Sun-sin Bridge, a suspension bridge having the world’s fourth longest main span, and Incheon Bridge, the world’s ninth longest cable-stayed bridge. Such achievements also led to progress of Sea-Crossing bridge construction technology in Korea.
Based on the experience of constructing long-span bridges in Korea and advanced technology, many Korean construction companies have aggressively entered the global long-span bridge construction markets for various activities in recent years, such as constructing the Third Bosphorus Bridge in Turkey that connects Europe and Asia and participating in the construction of the Chacao Channel bridge project in Chile.
Such technological advancement is appreciated as the outcome of continued efforts by the Ministry of Land, Infrastructure and Transport (MOLIT) and the entire construction industry. The Iksan Regional Construction and Management Administration is currently managing 17 Sea-Crossing bridges and constructing 20 additional bridges as a MOLIT-affiliated agency to have overall supervision over construction and management of general national highways along the southwestern coast. With such efforts, the Administration is becoming the world’s leading institution specializing in Sea-Crossing bridges and has been carrying out bridge construction projects with unprecedented vigor.
For the purpose of sharing and advancing core technologies in design, construction, and maintenance of Sea-Crossing bridges, the Administration held nine Sea- Crossing bridge technical seminars between 2011 and 2015 in consultation with relevant agencies.
The Administration now publishes the English edition of selected materials of Sea- Crossing bridge technical seminars held thus far with the goal of publicizing Korea’s Sea-Crossing bridge-related technologies and helping technicians and interested parties in other countries.
I sincerely hope this proceeding will offer an opportunity for readers to develop interest in special bridge projects and Korea’s technical prowess for Sea-Crossing bridge construction. I also ask for their interest in the annual Sea-Crossing bridge technical seminar.
MOLIT and the Administration pledge continued efforts to help South Korea to develop its technical power to the highest level and lead further technological advancement as a powerhouse of long-span Sea-Crossing bridge construction.
I would also like to extend my gratitude to the Korea Expressway Corporation, Korea Infrastructure Safety and Technology Corporation, Korea Institute of Civil Engineering and Building Technology, and other interested parties for supporting the annual Sea- Crossing bridge technical seminars and publishing this English-edition proceeding.
