The north-bound lane on Dunedin's Southern Motorway has reopened after a crash involving three vehicles earlier today.
Traffic on the motorway was severely affected for nearly four hours after a truck crashed into a 4WD and rolled before coming to rest upside down.
A police spokeswoman said it appeared the truck was travelling on Saddle Hill Rd when it crashed onto the motorway before rolling onto its roof off the road.
Emergency services were called about 3.30pm. A St John spokesman said two people had been taken to Dunedin Hospital by ambulance with minor injuries.
The north-bound lane had been closed between the Fairfield on-ramp and the Mosgiel off-ramp. The road was open to south-bound traffic.
About 7.15pm, the New Zealand Transport Agency advised that the north-bound lane had reopened.
Pictures taken at the scene showed that the truck collided with a 4WD towing a trailer.
A policeman at the scene said a third car was also hit.
Police said the truck driver had been freed, but there was no information on the extent of injuries.
A crane was on site to remove the truck.
