Contracted by China Railway Construction Corporation Limited, the eastern expansion line of the T3 terminal of Huanghua International Airport in Changsha, Central China's Hunan Province, was dug through on May 6. It is the world's first double-line medium- and low-speed magnetic levitation tunnel excavated with the shield engineering method.

Located in Huanghua Tow in Changsha, the project is 4.454 kilometers long and is a key section linking the Changsha South Railway Station and the T3 terminal of the Huanghua Airport.
The recently dug through tunnel is 2.8 kilometers long. The tunnel boring machine dug under the aviation fuel pipeline at the airport six times and dealt with several key risk source areas during construction. It was the first time that the shield engineering had been conducted underground at the airport.
The project is a key support to development of the magnetic levitation industry and a major part of the highway network within the Changsha, Zhuzhou and Xiangtan city cluster. It is expected to be of great significance in building of an integrated traffic hub centered by Changsha Huanghua International Airport.
Once operational, travel time between the T2 and T3 terminals of the airport will be shortened to two minutes.
