First undersea tunnel coming for fast trains

China will complete its first undersea tunnel for high-speed trains by 2025, connecting the Zhoushan Islands in eastern Zhejiang province with the mainland, according to local authorities.

Sources from the Zhoushan development and reform commission said progress has been made on the first-phase feasibility study for the massive project, which was initiated in June last year. Construction is expected to begin next year.

On Nov 19, a feasibility evaluation for the new railway was made in Beijing, a significant step before construction begins.
