Recently, the concept of using a highway joint area is not just a limited place for solving physiological phenomena of highway users, but it is a comprehensive convenience facility that provides rest and convenience for drivers and passengers by providing parking spaces, restaurants, convenience stores, and toilets. In recent years, these highway rest facilities have become complex facilities, and large-scale developments have been made, so seven locations across the country have been developed. Meanwhile, the Korea Expressway Corporation has exclusive powers to develop highway junctions. The method of study is case analysis. As a result, the West Coast Expressway has already developed a joint area and outlet on the Haengdam-do site, and plans to further develop it in the future. However, in order to achieve both the goals of public interest and profitability, the development of these exclusive joint areas requires establishing the basic direction of development before development. Therefore, this study analyzed cases of Haengdam-do and presented feasibility in development and suggested the development of the linkage of local tourism resources rather than a simple food and beverage-oriented rental business. Through this, it is possible to expect a synergistic effect of using the expressway to tour the joint development site, rather than a brief stopover while using the expressway.
