Roads partially reopen at Bangkok tunnel leak site

Traffic has partially resumed on Bangkok's Prajadhipok Road following repairs to a leaking Purple Line rail tunnel. The inbound lanes near Wongwian Yai reopened Sunday morning, though outbound lanes remain closed. The Mass Rapid Transit Authority (MRTA) reported that three inbound lanes are now accessible from Wongwian Yai to Ban Khaek intersection.

The road had been shut for two weeks after water began leaking into the tunnel, which is still under construction, causing subsidence. The MRTA stated that the contractor is actively grouting the tunnel, located 37 meters underground, to stop the water ingress. Motorists can use Lat Ya Road as an alternative route.

Engineers closely observing the site have reported no indications of building movement within a 30-meter radius of the leak. Furthermore, no additional subsidence has occurred along Prajadhipok Road since the initial detection. The situation remains under active repair as authorities work to secure the tunnel and surrounding infrastructure.
