Big changes are coming to the intersection of Eden and Reed Sts in Oamaru.
In the coming weeks, a roundabout will be installed at the crossroads.
Waitaki District Council roading manager Michael Voss said the council had tested 19m truck and trailers navigating the layout, which had been a success.
The roundabout, costing $80,000, was expected to be finished by the second week of February.
Waitaki Mayor Gary Kircher believed the roundabout would make the intersection easier and safer for both drivers and pedestrians.
“I’m convinced that it will be a lot better,” he said.
Mr Kircher believed traffic lights – one of the ideas that were considered by the council – were too expensive.
“The problem with traffic lights is it does stop traffic,” he said.
“It’s not as efficient, because whether there’s something coming or not, the light goes red [and] you’ve got to stop, and you’ve got to wait until it goes green.
“[Roundabouts] are very easy, very straightforward [and] I’m very certain that it’s going to make things a lot safer there.”
Last year, it was estimated the intersection was used by 7664 vehicles a day, including 320 heavy vehicles.
A roundabout was also planned for the intersection of Wansbeck and Tyne Sts, where visitor traffic has increased significantly in recent times.
