The Busan Metropolitan Government will implement phased partial traffic control measures to replace the aging delineators in the Yeonsan Tunnel and Daeti Tunnel.


On July 19, the city announced that it would carry out replacement works for delineators in the Yeonsan and Daeti tunnels to enhance visibility for tunnel drivers and ensure traffic safety.


Construction in the Yeonsan Tunnel will take place from July 20 to 24. To avoid peak commute hours, partial traffic control will be enforced twice daily: from 9:00 a.m. to 5:00 p.m. and from 10:00 p.m. to 5:00 a.m. the following day.

For the Daeti Tunnel, the work will be conducted from July 27 to August 14. Considering heavy daytime traffic volumes, partial traffic control will only be enforced during nighttime hours, from 10:00 p.m. to 6:00 a.m. the next day.


The city plans to maintain vehicle traffic through partial control in both tunnels to minimize inconvenience to citizens. No traffic control will be implemented on public holidays or weekends, and the construction will be carried out by Yuwon Electric Co., Ltd.



Jin Bong-sang, Director of the Busan Construction Safety Testing Office, stated, "We will complete the construction safely and swiftly to minimize inconvenience for citizens and shorten the traffic control period," and asked for citizens' cooperation and understanding during the construction and traffic control periods.
