Gas leak linked to Sydney light rail

A ruptured gas main near the Sydney light rail project has caused part of the CBD to be shut down.

A 200-metre exclusion zone was put in place between George and Hunter streets in Sydney on Monday afternoon after the main ruptured.

Firefighters responded to the leak after 12.30pm, with the exclusion zone lifted before 2pm.

Initial reports suggest the leak occurred within the CBD light rail construction area, according to Fire and Rescue NSW.
