Bangkok’s MRT Blue Line extension tunnel has been unaffected by a partial road collapse above its alignment in the city’s Chinatown area, Transport Minister Chadchart Sittipunt has told Thai news agencies. According to Thai media outlet ‘The Nation’, part of the road surface on Charoenkrung Road subsided at roughly 2am yesterday, leaving a 25cm deep crater at the MRT Blue Line’s extension construction site.
Construction supervisor Kamol Mahaphon ordered workers to dig further to investigate the cause of the subsidence when the team discovered a massive water leak that had seriously weakened the structural stability of the area. The Metropolitan Waterworks Authority has been informed.
Chadchart said the MRT tunnel, under construction at a depth of some 25m, remains intact. “The tunnel has not been damaged in any way,” The Nation reports the Minister as saying.
