Police called to deal with a crash on the expressway overbridge at Meeanee yesterday morning were just clearing the scene when they were alerted to a second accident just 3km away on the stretch of road.
Like the first crash, the second was the result of a driver failing to slow down in time as the result of traffic slowing and queuing.
The first crash happened about 7.45am after the driver of a van lost control and swerved into a second vehicle about half-way across the overbridge.
A police spokesman said traffic was moving slow at the time and vehicles were queuing up.
The crash completely blocked the roadway and police put in diversions using the sliproads to the bridge.
