Melbourne’s suitably apocalyptic sinkhole – which we’re hereby dubbing the Collins Street Abyss – is still causing traffic problems in the CBD.

The street’s eastbound lane is closed between Queen and Elizabeth Streets and is likely to remain closed until Monday.

The sinkhole, caused by a crack in a barrel drain strangled by tree roots, was discovered early on Tuesday morning and is roughly one metre wide and two metres deep.

Melbourne City Council crews have expanded the sinkhole to around five metres underground to repair the damage, 7 News reports.

“Crews are continuing to work the roadway and drainage on Collins Street,” the council said in a statement on Wednesday.

“The sinkhole that developed on Tuesday morning appears to have been caused by a crack in the barrel drain running down Collins Street.

“The eastbound side of Collins Street remains closed between Queen and Elizabeth Streets. We expect the road to reopen on Monday.”

Drivers are advised to take La Trobe, Lonsdale or Bourke Streets instead.

The area is cordoned off to pedestrians but you can stare into the abyss via 7 News.
