The area in the vicinity of Songjeong Beach had been developed since 1975, and was developed to the port as cement supply base thanks to its abundant limestone resources, thereby contributing to nation's economic development. In the wake of phase 2 development project finished in November 1999, its logistics handling environment has been significantly improved on the back of expanded harbor facility with Yeongdong and Donghae expressway. With geological advantages in trading with China, Russia and Japan, its function as base port for trading with the nations in the north will be further expanded. At the mouth of a river running along the port, a ferry for small boats with many anglers is available.
