China will build its first undersea tunnel for high-speed trains, connecting two cities in eastern province of Zhejiang which will substantially cut the travel time from 90 to 30 minutes, according to a media report.
The total length of the project is 70.92 km, with an undersea tunnel section of 16.2 km, which will connect the city of Ningbo with the island city of Zhoushan in east Zhejiang, state-run Xinhua news agency reported.
The trains are designed to run at 250 km per hour, cutting the trip between the two cities from 1.5 hours to less than 30 minutes.
China's high-speed rail has reached 25,000 kms in length, accounting for more than 60 percent of the world's total.
Zhejiang was among the earliest provinces in the country to build high-speed rail.
