A huge sinkhole opened up as a road collapsed near an under-construction metro station in southern China.

The incident was filmed in Chengdu City, Sichuan Province, on June 21.

Residents from nearby neighbourhoods reported hearing a loud noise followed by the appearance of a large hole in the road, exposing a void underneath.

Authorities swiftly responded to the scene after the incident. Preliminary surveys revealed that the collapse was caused by the rupture of two water pipes, one with a diameter of one metre and the other 0.3 metres, buried approximately two metres deep. The rupture resulted in a crater approximately 12 metres long and 10 metres wide.

Luckily, due to the early hour of the incident, few pedestrians were present, averting any casualties.

Emergency protocols were immediately activated, with authorities shutting off the burst water pipes and closing the affected area with barriers to ensure safety. Traffic control measures were implemented, redirecting vehicles to alternative routes to maintain safety.

Currently, the incident has not directly impacted the construction and operation of Chengdu's rail transit system. Authorities are conducting a thorough investigation into the cause of the incident and have begun repairs to restore normal traffic conditions promptly.

6月21日凌晨3时50分左右，成都市地铁13号线小南街站在建站点附近发生一起路面塌陷事故。据初步调查，事故原因系地下自来水管自然爆裂所致，所幸未造成人员伤亡。

据了解，事故发生地点位于锦里西路119号附近。附近的小区居民称，突然听到一声巨响，随后发现路面出现一个大坑，露出地面下的空洞。

事故发生后，相关部门迅速赶到现场进行处置。经初步勘查，事故原因系两根自来水管的爆裂，这两根自来水管一根直径1米，另一根直径0.3米，埋深约2米。水管爆裂导致了路面塌陷，形成一个长约12米、宽数米的大坑。
幸运的是，由于事发时为凌晨，路上行人稀少，因此未造成人员伤亡。

事故发生后，相关部门立即启动应急预案，关闭爆裂的自来水管，并对受影响的路段进行封闭，设置围挡以确保现场安全。同时，交通管理部门也对该路段进行了交通管制，引导车辆绕行，确保交通安全。

目前，事故未对成都轨道交通建设及运营造成直接影响。相关部门正在对事故原因进行深入调查，并着手进行路面修复工作，以尽快恢复交通秩序。
