The illegal placement of a road sign in an inner-Brisbane bike lane had been called “stupidity” by local councillor Jonathan Sri.

Temporary construction signage was placed in the bike lane on Dornoch Terrace in Highgate Hill on Wednesday, blocking both the uphill and downhill bike lanes on the street.

Green councillor Jonathan Sri said the road sign was meant to alert people to an upcoming danger but turned out to be more dangerous than the hazard it was pointing to.

"Sadly this sort of stupidity is all too common around Brisbane," he said.
