Cracks beneath Shanghai-Beijing bullet train bridge not affecting railway, officials say

The surface of a road beneath the Beijing-Shanghai High Speed Railway subsided and cracked in Minhang District, but officials said today that it had no impact on the railway operation.

Over 100 square meters of the roadbed on Tianshan Road W. where a bridge pier for the rail stands started cracking while some areas subsided about 1 meter.

Trains of the high speed railway between Shanghai and Beijing run across the bridge about every three minutes.

Several cracks - about 30 centimeters wide and 10 meters long - appeared in a restricted area around the bridge pier.

"The cracks have appeared for a while and high-speed trains kept running over," a nearby resident said.

The area cracked under the railway bridge is neither the roadbed nor the pier foundation, but only a pack of wasted concrete covering the road, an official with the Shanghai Railway Bureau said.

"The cracks will not affect the operation of the Beijing-Shanghai High Speed Railway," the official said.

He said the bureau has long noticed the cracks, but found it was only some wasted concrete piled on the ground after the completion on the railway project. The concrete became solid and covered the ground, which cracked and subsided after years of rain.

The high-speed railway line linking Beijing and Shanghai has recorded over 100 million passenger trips since it started operation in June 2012. Built with an investment of 217.6 billion yuan (US$34.7 billion), the 1,318-kilometer-long railway has shortened the travel time between the two major cities to about five hours from the previous eight hours or more.
