Both patients could be seen being treated by paramedics before two rescue helicopters arrived.
The spokeswoman said the northbound lanes were closed with diversions in place, and the south bound lanes would be closed to allow the rescue helicopters to land.
"Those travelling northbound are advised to take Trent St."
Drivers are being urged to avoid the area and the Serious Crash Unit have been notified, she said.
