Will Gyeongnam's urban traffic be relieved? Opening of Gyeongnam National Road 58 at Samgye Intersection

A segment of the Muge-Samgye detour road construction project on National Road 58, a major traffic network in Gyeongnam, will open at 2 PM on June 25, 2025. The section to be opened corresponds to approximately 1.3km of the main line at Samgye Intersection, which is the unfinished portion of the Juchon-Samgye section that partially opened last October.
With this opening, vehicles heading from Juchon in the direction of Saenglim will be able to directly enter and exit the main line. Consequently, traffic flow in the surrounding areas is expected to improve somewhat. In particular, the movement of vehicles traveling to and from Gyeongnam Lotte Outlet Water Park, Jangyu Eungdal, and Samgye-dong is expected to become smoother. These changes are anticipated to have a positive impact on local residents and visitors.
Significance of the Opening and Future Plans

The Muge-Samgye detour road project, supervised by the Busan Land Management Office, is opening now. This project spans a total length of 13.76 km and has a budget of 477.2 billion won.
Since its groundbreaking in March 2008, the project has now reached the final stages after 17 years, and all sections are expected to open this December, significantly enhancing traffic convenience.
A main road connecting Jangyu-dong Eungdal and Samgye-dong has been opened to the main line. Consequently, the existing temporary ramps between Juchon Intersection and Samgye Intersection have been closed for safety reasons.
Therefore, drivers must use nearby intersections for U-turns. In particular, drivers entering from the Samgye direction should pay attention to the new road usage methods.
Expected Effects Before All Sections of the Road Open

When all sections open by the end of 2025, it is expected to effectively resolve traffic congestion issues in Gyeongnam city, connecting with the Jinhae Ungdong-Jangyu Eungdal section that opened in 2019.
In particular, congestion areas around West Gyeongnam IC, Jangyu, and Samgye will be improved, leading to smoother access to Jinhae New Port and Geoga Bridge. This is expected to greatly enhance the logistics flow between regions.
During the summer, access to Gyeongnam Lotte Outlet Water Park, a popular destination for families, is anticipated to increase, positively impacting local tourism. These changes will be tremendously beneficial to the Gyeongnam local economy.
Conclusion

The 1.3km section of Gyeongnam National Road 58 at Samgye Intersection has been opened. This means more than just a simple road connection. It is expected to be a crucial turning point for the improvement of the entire traffic network in Gyeongnam and the activation of logistics and tourism.
Once the entire section opens by the end of this year, the connectivity and accessibility between the urban center and the outside will be greatly enhanced. While using the road, it is important to adjust driving habits according to the newly changed structure and to check the signage.
