Banora Point upgrade controlled blasting begins tomorrow

18 July 2011

Controlled blasting will begin tomorrow as part of the Pacific Highway Banora Point upgrade.

“Controlled blasting is carried out to break up very hard rock that can’t be broken using traditional machinery,” a Roads and Traffic Authority spokesperson said.

“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.

“A more level road means cars use less fuel and make less noise when accelerating and braking, particularly heavy vehicles.

“Controlled blasting will be carried out at Sexton Hill from Tuesday 19 July for around four months. Two blasts a week will take place between 12 and 2pm, on days when traffic on the highway is least busy.

“The blasting is being carried out between these set times to allow road users to plan their journeys.

“Safety and protecting the community’s property are paramount during controlled blasting activities and the project team has engaged contractors who are very experienced in carrying out safe controlled blasting,” the spokesperson said.

Despite the fact blasting is a controlled process which often goes unnoticed by the surrounding community, detailed planning and safety procedures are put in place.

“Controlled blasting is subject to strict environmental controls, including managing noise and vibration. The approved vibration limits specified for the project only allow small quantities of material to be blasted each time,” the spokesperson said.

Controlled blasting monitoring results, including vibration reports will be available on the project’s website at or from the project’s community information centre, east of the Darlington Drive roundabout

“Temporary road closures, including closure of access to Wilson Park and some private properties, will be in place for the safety of residents, motorists and livestock,” the spokesperson said.

Roadside signs will in place to notify road users of the blast activities.

TheRoads and Traffic Authority thanks the community for their cooperation during controlled blasting and will ensure disruption is kept to a minimum.
