Gwangju–Daegu Expressway
Overview
The Gwangju–Daegu Expressway (Expressway No. 12) is an approximately 176 km expressway connecting Gwangju Metropolitan City and Daegu Metropolitan City. Construction began in 1984 and the entire section opened in 1990. As a key east–west transportation axis linking the Honam and Yeongnam regions, it contributes to freight and passenger transport and regional economic integration.

History and Construction Background
As part of the economic development plans of the 1980s, the need to expand transportation infrastructure between Honam and Yeongnam led to the construction of the Gwangju–Daegu Expressway. Construction started in December 1984, and the entire section opened in December 1990, with a total project cost of approximately 1.2 trillion won (at the time). Initially a four-lane round-trip road, some sections have since been widened due to increased traffic.
Route and Major Facilities
The Gwangju–Daegu Expressway begins at Munheung Junction in Buk-gu, Gwangju, and passes through Damyang County (Jeollanam-do), Sunchang County and Namwon City (Jeollabuk-do), Hamyang County and Geochang County (Gyeongsangnam-do), and Goryeong County (Gyeongsangbuk-do), ending at Seongseo Junction in Dalseo-gu, Daegu. Major interchanges (IC) include Damyang IC, Sunchang IC, Namwon IC, Hamyang IC, Geochang IC, and Goryeong IC. Service areas in operation include Damyang Service Area, Namwon Service Area, Hamyang Service Area, and Geochang Service Area. In particular, sections passing near Jirisan and Deogyusan mountains offer scenic views, making it a popular driving course.
Traffic Volume and Operational Status
As of 2023, the average daily traffic volume on the Gwangju–Daegu Expressway is approximately 45,000 vehicles, more than triple the volume at the time of opening. Major traffic patterns consist of long-distance travel between Gwangju and Daegu (about 40%) and medium- to short-distance travel between regions (about 60%). The proportion of freight vehicles is about 25%, playing a crucial role in the logistics of agricultural, fishery, and industrial products. Recent operational efficiency improvements include the expansion of electric vehicle charging stations and the introduction of a smart tolling system.
Economic Impact
The Gwangju–Daegu Expressway has promoted economic integration between Honam and Yeongnam. Travel time between Gwangju and Daegu has been reduced from 4 hours to 2 hours and 30 minutes, contributing to lower corporate logistics costs and tourism revitalization. It has directly influenced the economic development of intermediate areas such as Damyang, Sunchang, Namwon, Hamyang, and Geochang, facilitating the distribution of local specialties (e.g., Korean rice cakes, Korean beef, apples) to the Seoul Capital Area and Yeongnam region. Additionally, the establishment of industrial complexes and logistics centers along the expressway has created job opportunities.
Safety and Environmental Issues
In sections adjacent to Jirisan and Deogyusan National Parks, measures to prevent wildlife roadkill (e.g., ecological corridors, fences) are in place. Since 2020, an advanced weather information system has been introduced for sections vulnerable to fog and icing, and in 2023, a smart shoulder lane system was piloted in some sections. Environmental groups are demanding that ecosystem damage be minimized during expressway expansion projects.
Latest Trends
As of 2024, the Gwangju–Daegu Expressway is undergoing a smart expressway conversion project along with repairs to aging pavement. By 2025, a Cooperative-Intelligent Transport System (C-ITS) will be established across the entire section to provide real-time traffic information and expand infrastructure supporting autonomous driving. Additionally, expansion of transfer parking lots linked to the Gwangju–Daegu KTX-Ieum line and additional installation of rapid electric vehicle charging stations (from 8 to 12 per service area) are underway. In March 2024, traffic volume on the Gwangju–Daegu Expressway fully recovered to pre-COVID-19 levels, with weekend tourism demand increasing by 20%. Meanwhile, discussions on toll increases began in earnest in the second half of 2024, raising the possibility of a toll hike in the first half of 2025.
