M5 tunnel chaos after faulty fan sparks closure

A faulty ventilation fan in Sydney's M5 toll tunnel forced the closure of the city-bound lanes for approximately seven hours, creating traffic delays stretching up to 13 kilometres. The broken fan was discovered during routine checks in the early hours and wasn't properly secured to the ceiling, prompting tunnel operator Transurban to carry out urgent repairs using multiple cranes. The tunnel has since reopened with traffic flowing normally.See omnystudio.com/listener for privacy information.
