The history of the Oxley Highway speed review starts in July 2105 with the publication of the Oxley Highway Route Safety Review.
It found the highway had just over twice as high a casualty crash rate as other NSW country roads (30% v 14%).
Of the 415 casualties from 2008 to 2012 on the Oxley, the majority were drivers (49%), motorcyclists (24%) and motor vehicle passengers (21%).
Motorcycles were involved in 96 casualty crashes from 2008 to 2012 with one fatal in 2013.
Just over three quarters (78%) of all motorcycle injury crashes involved a single vehicle and more than half (56%) of the riders involved were locals.
The review made 14 recommendations including removing roadside hazards, adjusting barriers, better line-marking, improving the road, expanding mobile phone coverage and an education campaign particularly targeting riders.
It also recommended reviewing speed zones.
Guess which won!
In September 2016, temporary electronic signs were installed warning motorists of speed changes which included dropping the speed limit to 60km/h from 100km/h on the mountain stretch.
That triggered protests by riders and many local business operators and residents concerned about delays and impact on businesses with a subsequent drop of riders and tourists.
