Trinity Road will remain closed until Thursday, with only residential access to Trinity Gardens allowed.
Following the incident, a listening stick was used by a Jersey Water employee to detect whether there was any running water underneath the section of road.
A spokesman from Jersey Water said: ‘We monitor the roads on a regular basis and we inspected that particular road last week and everything was fine.
‘When a member of the team checked on Monday, they could hear that there was running water. A small pipe had burst which is feeding water to one property on the road.
‘It is possible that the pipe burst as a result of the road collapsing, but we won’t know until further work has taken place.’
It is not the first time that a void has appeared in the area. In 2013 the road was closed after a hole opened up.
And in 2009 a burst water main created a hole in an almost identical spot, causing major traffic disruptions for a week.
So, what is a listening stick?
- These tools have been used to detect burst pipes in Jersey since the water network became operational in 1882
- The device is entirely made of wood and one end is placed on the road surface over the pipe network, while the other flat end is placed to someones ear. The individual then listens for any vibrations which indicate running water is present.
- Although there are more modern ways of detecting a burst water pipe, a spokesman from Jersey Water said that the sticks were the most effective method.
