He said the existing taper for motorists crossing to head south on Marine Parade was too short. It had led to some confusion for motorists, and what the local spoken to referred to as "a few near-misses". Cars would cross from Warren St on to Marine Parade via the thin entranceway, heading south, often without checking to see if any vehicles were approaching from their left. Near-accidents had resulted.
"I've also seen someone drive along and do a U-turn back up the entranceway - it's confusing."
Mr Wright said the roundabout would greatly improve safety.
It would also greatly improve the landscape, because gardens would be part of its centrepiece and pathways would "look after pedestrians" around it.
"A nice-looking entrance to the city," he said.
The construction had meant 10 Norfolk pines in the immediate area needed to be fully fenced off to prevent accidental damage.
"The trees won't be going. We just don't want any excavations to damage their roots."
A 30km/h speed restriction had been put in place while the work was done.
