Even the Wellington City Council agrees a 20 centimetre-wide painted cycle lane in Wellington's CBD looks a bit weird.

Images on social media joke it's the council's attempt at the world's narrowest cycle lane.

But a spokesperson says the cycleway on Greys Ave hasn't been finished properly - and contractors will be asked to widen the route as soon as possible.

Skeleton crews over the holiday period have meant it couldn't be fixed sooner.
