New Beijing airport's ground transportation construction finished

The main structure of the high-speed expressway connecting the Beijing Daxing International Airport to the capital completed construction on Sunday.

That means the ground transport lines connecting to the new airport have been completed, overcoming many construction challenges, according to CCTV reports on Sunday.

Four bridges on three major transport lines connecting the new airport had completed swivel construction at 2 am on Sunday after 90-minutes of night work, CCTV reported.

The total weight of the four bridges is about 10,000 tons, with 70 degrees of maximum rotation, local authorities said.

Zhang Yanduo, expressway project manager of the new airport from the Beijing Infrastructure Investment Co., said the implementation of the rotation plan for four bridges in synchronization on the expressway is the first of its kind at home and abroad.

Major challenges include that the window for rotation is only 90 minutes due to the busy transportation activity on the Beijing-Shanghai railway, which passes through the project construction areas. The time for construction has to be accurate to even single seconds.

Located on the border of Beijing and Langfang, North China's Hebei province, the new airport, which will be the capital's second international airport, aims to be a transportation hub amid the Beijing-Tianjin-Hebei region when construction is completed.
