A section of Dunedin's southern motorway through Green Island will be closed this Friday morning.
The Transport Agency website says the motorway will be closed from the Green Island off-ramp, between 9am and midday, for a police operation.
A police spokesperson says staff will be carrying out further scene examination work in relation to a fatal crash on the motorway earlier this month.
The Concord on-ramp will also be closed, and all traffic will be diverted through Green Island.
