Minimal fuss as rock cops a blast
BANORA Point residents may have felt a little extra vibration from the Pacific Highway upgrade roadworks yesterday.
Controlled blasting began at noon to break up hard rock that couldn't be broken with conventional machinery and will continue twice a week for the next four months.
An RTA spokesman said all the necessary precautions had been taken to ensure the safety of residents and motorists despite the fact it often goes unnoticed by the surrounding community.
“Controlled blasting is subject to strict environmental controls, including managing noise and
vibration,” he said.
“The approved vibration limits specified for the project only allow small quantities of material to be blasted each time.”
The spokesman said the blasting was necessary to create the best route for the new highway.
“The Banora Point upgrade route was designed to minimise the amount of rock needed to be excavated while providing a gentle slope for drivers using the road,” he said.
“A more level road means cars use less fuel and make less noise when accelerating and braking, particularly heavy vehicles.”
Traffic control and road closures will be in place twice a week for the next four months between noon and 2pm when the road use is minimal.
