The Seoul-Busan Highway is the first and arguably the most important national highway of South Korea. It represents the main artery of Korea and the start of nation’s economic development. Along the route of this major freeway, sits two cities Eonyang city and Yeongcheon city. The area between the two cities has not been touched in 50 years. So it’s no surprise that their dangerously winding, old, and narrow roads along decrepit outdated facilities have been the cause of frequent accidents, and traffic jams.

It was up to Hanwha Corporation/E&C to improve this important highway, appropriately labeled Route 1. It meant improving the area this national road straddled Eonyang city and Yeongcheon city. The expansion of the Eonyang ~Yeongcheon area involved increasing the number of lanes from 4 to 6, and improving the road course to significantly reduce traffic jams.

The expansion project needed to be completed without interfering the non-stop 24/7 traffic flow, so the proper work zones and traffic transitions were set up with all the temporary traffic signs, signals, and barricades to ensure the protection of the public, workers and equipment, day and night. During the 7 years it took to complete the expansion project, Hanwha Corporation/E&C had zero accidents and this was attributed to the company’s expertise and experience in road construction.
