Recently, the reporter learned from Jinghe marketing department that the "throat project" - Jinggangshan tunnel lighting project of Jingmu expressway, which was originally planned to be officially opened to traffic at the end of this year, has been completed and turned on. LED lamps have been used in the lighting of this so-called long tunnel in Jiangxi. The completion of Jinggangshan tunnel lighting project marks the completion of Jingmu expressway, which lasted three years in Jiangxi Province, and can be put into use.

Jinggangshan tunnel of Jingmu Expressway crosses the erling section of Luoxiao mountains. It is the main control project of Jingmu project and a long highway tunnel in Jiangxi Province. The surrounding rock of the tunnel is complex, with abundant water, many broken zones, high safety risks and poor lighting environment. The total length of the tunnel is 6850m. All LED tunnel lamps supplied by medium energy-saving crystal and lighting are used. LED tunnel lamps save more than 50% energy than traditional high-pressure sodium lamps. Tunnel lighting takes a long time, and LED has excellent intelligent control performance. After the intelligent control system is combined with tunnel lighting, the energy saving of LED tunnel lighting will be increased by 20%.

The construction of Jingmu expressway was started in January 2011, with a total length of 43.318 km. The line is another Provincial Expressway in Jiangxi. The Jingmu Expressway starts from Xiaping Town, Jinggangshan, connects with Taijing expressway through interchange, and ends at the junction of Mianyang Town, Yanling County, Hunan and Mucun Township, Jinggangshan, Jiangxi, connecting with yanmu Expressway in Hunan. After Jingmu expressway is opened to traffic, the travel time from Jinggangshan to Yanling will be shortened from nearly 2 hours to 50 minutes, forming a tourism fast track for Jinggangshan, YanDiLing, Hengshan and other national scenic spots.
