*The period from the 1990s to the early 2000s was considered a time to attempt a more specific project approach from a general and comprehensive perspective based on previous research materials, and we have been working hard on various publicity and educational activities both domestically and internationally. Based on these results, we are currently formulating our second business plan while continuing to study further.
Since its proposal in 1981, this project had been carried out under the direction and supervision of the International Highway Construction Corporation, butin January 2009, the International Highway Foundation, a general incorporated foundation, took over the project.
