Traffic Restrictions at Busan Tunnel for Installation of an Automatic Fire-Activated Smoke Control System

내용

Busan Metropolitan City's Construction Safety Testing Office announced that traffic restrictions will be implemented in both directions of Busan Tunnel (Yeongju-dong ↔ Daesin-dong) from October 19 to 29 to facilitate the installation of an automatic fire-activated smoke control system.

The automatic fire-activated smoke control system is designed to activate smoke control equipment automatically in response to a fire alarm signal in the event of a tunnel fire, preventing the spread of smoke and toxic gases.

The project aims to provide a safer road environment for citizens through the installation of the system. Construction will be undertaken by Dongyoung Tech One Co., Ltd.

Construction will be carried out in two phases for each direction, with work scheduled only between 11:00 p.m. and 5:00 a.m. the following day to avoid morning and evening rush hours and minimize traffic congestion.

The first phase will involve installation of the system, followed by a second phase for testing and commissioning.

The first phase of construction in the uphill direction (Yeongju-dong → Daesin-dong) will take place from October 19 to 22. Both uphill lanes will be fully closed, while the two downhill lanes (Daesin-dong → Yeongju-dong) will be temporarily operated to accommodate traffic in both directions.

The second phase, involving system testing and commissioning, will take place from October 27 to 28 under the same traffic arrangements.

The first phase of construction in the downhill direction (Daesin-dong → Yeongju-dong) will then take place from October 22 to 27. During this period, traffic restrictions will be limited to one downhill lane, while uphill traffic will operate normally.

The second phase, involving system testing and commissioning, will take place from October 28 to 29 under the same traffic arrangements.

Jin Bong-sang, Director of the Construction Safety Testing Office of Busan Metropolitan City, stated, "We will prioritize safety and complete the construction work as quickly as possible to minimize inconvenience to citizens caused by the traffic restrictions."

He added, "We sincerely ask for the understanding and cooperation of all citizens to ensure that the construction work proceeds safely and efficiently."
