20 April

Original route of the Circle Line (grey) following Nicoll Highway (pink), and the realigned route (orange)

The Nicoll Highway collapse occurred in Singapore on 20 April 2004 when a Mass Rapid Transit tunnel construction site caved in near the highway next to the Merdeka Bridge. Four workers were killed and three were injured, delaying the construction of the Circle Line. The collapse was caused by a poorly designed strut-waler support system, a lack of monitoring and proper management of data caused by human error, and organisational failures of the construction contractors and the Land Transport Authority. Following the incident, the collapsed site was refilled, and the highway was reinstated and reopened to traffic on 4 December 2004. The authorities revised their construction safety measures to be above industry standards. The Circle Line tunnels were realigned (map pictured), with Nicoll Highway station rebuilt underneath Republic Avenue, to the south of the original site. The station and tunnels opened on 17 April 2010, three years later than planned. (Full article...)
