The Dunedin City Council has confirmed temporary safety improvements introduced in March last year were about to become permanent.
The work, at the intersection of Brown St and Elm Row, would replace a temporary roundabout with a permanent one, Dunedin City Council transport engineering and road safety team leader Hjarne Poulsen said.
Temporary bollards would be replaced with two new crossing points, including kerb buildouts and a pedestrian refuge island, he said.
The temporary roundabout, introduced as a trial, had slowed traffic, improved pedestrian accessibility and made the intersection safer, he said.
"The permanent roundabout will provide safer access to St Joseph's Cathedral School and improve the look of the intersection."
A new crossing with kerb buildouts and a refuge island would also be added at the Brown and Duncan Sts intersection.
Parking changes in Duncan St would also result in six parallel parks being converted to 10 angle parks, to narrow the street and slow traffic speeds, he said.
The improvements were the first stage of permanent changes being rolled out as part of the Central City Schools Cluster safety programme, and were expected to be completed by the end of June at a cost of $467,000.
Work on second and third stages of the cluster was expected to begin later this year.
