Concerns are being raised about an "edgy" design allowing cars and pedestrians to share Garden Place in Hamilton amid fears that a lack of signs will make it potentially dangerous.
Hamilton City councillor Ewan Wilson said he did not want to wait for someone to be hit before they decided to put up speed signs warning people to slow down.
"I think people are going to get really hurt here so it doesn't have my support unless we take some fundamental steps and get some signage."
He said it would not be obvious to people travelling at 30km/h on surrounding streets to then go down to a crawl through Garden Place.
The finance and monitoring committee was commenting on the latest shared space design that would link the roads between Worley Place and Alexandra St and be used by pedestrians and vehicles without any kerbing and limited markings and bollards. Work on the new tree-lined lane would begin in March and is due to be completed by June.
