Nicoll Highway collapse : ウィキペディア英語版 | Nicoll Highway collapse
The Nicoll Highway collapse was a construction accident that occurred at approximately 3:30 p.m. Singapore Time (UTC+8:00) on 20 April 2004 in Singapore when a tunnel being constructed for use by MRT trains collapsed. The tunnel was part of the construction of the underground Circle Line, near Nicoll Highway station. The supporting structure for the deep excavation work failed, resulting in a 30-metre (100 ft) deep cave-in that spread across six lanes of Nicoll Highway. The collapse killed four people and injured three. The accident delayed the construction end date for the MRT station. ==Causes== Investigations and probes into the collapse commenced immediately. It eventually was found that the most apparent cause of the collapse was that the retaining wall could not handle the stress of holding up the tunnel, forcing it to give way. This occurred near the Nicoll Highway MRT station under construction along the Circle Line and near the Merdeka Bridge.
