Prajadhipok Road inbound reopens after MRT Purple Line tunnel leak

10 Sept 18:58 Key points summarised by AI
  • Prajadhipok Road's three inbound lanes reopened to 24-hour traffic following successful efforts to control a water leak in the MRT Southern Purple Line extension tunnel.
  • Bangkok Governor Chadchart Sittipunt confirmed the situation stabilized through measures including sealing tunnel ends, injecting water to balance subterranean pressure, and soil reinforcement.
  • Engineers effectively equalized pressure using just over 1,000 cubic meters of water, significantly less than the 10,000 cubic meters initially planned.
  • Continuous ground-grouting operations to a depth of 37 meters successfully halted water ingress, with no further ground subsidence or structural movement detected in nearby buildings.
  • Outbound lanes will remain closed to ensure worker safety during additional tunnel reinforcement work.
