Work begins on the Pacific Highway to install audio tactile line marking tomorrow, Monday, August 18.

The audio tactile line marking, also known as rumble strips, will be installed between Harwood and Tweed Heads.

Transport for NSW’s Greg Collins said the rumble strips reduce the risk of head-on and run-off-road crashes by alerting drivers if their vehicle starts to veer out of their lane, and will be installed on almost 100 kilometres of the dual carriageway.

“If a vehicle leaves its lane where ATLM is installed, whether through fatigue, distraction or inattention, the rumble strips make a noise to immediately alert the driver to take corrective action to avoid a serious accident,” he said.

“This makes them particularly effective at night or in bad weather, and can reduce the number of crashes by 15 to 25 per cent, saving lives and preventing injuries.”

Upcoming work on the Pacific Highway will be carried out from Harwood to Tweed Heads, where a total of 300 kilometres of rumble strips will be installed over 96 kilometres of road.

Crews will be working on this section of the highway from Monday, August 18 from 6am to 6pm Monday–Saturdays. Some work may be carried out at night between 8pm and 4am. Work is expected to be completed by December 19.

Lane closures and a reduced speed limit of 40km/h will be in place during the work.

The work on the Pacific Highway is just one part of the $46 million Saving Lives Accelerated Program.
