City of Melbourne crews are continuing an investigation into the road surface on Collins Street after a sinkhole developed on the roadway this morning.
Crews used CCTV drainage robot cameras to confirm the issue was caused by a crack in the barrel drain running down Collins Street.
We are currently repairing the road surface and drain and expect the road to re-open tomorrow. Traffic diversions are in place for cars travelling eastbound on Collins Street, the road closes at Queen Street. Westbound traffic and trams remain unaffected. We thank drivers for their patience.
