Rumble strips, also known as audio-tactile line markings, are small bumps that make a ‘rumbling’ sound and cause a vehicle to vibrate when driven over, alerting drivers that they’re moving out of their lane and helping to prevent head-on or run-off-road collisions.

In coming months, we'll install rumble strips along 3,200 kilometres of roads in south western Victoria, as part of a state-wide program to improve safety on rural and regional roads.

In May and June, we'll be installing rumble strips at these locations:

Road From/To Location
Penshurst-Dunkeld Road
Penhurst to the Glenelg Highway                 
Penshurst-Port Fairy Road
Princes Highway West to Penshurst-Warrnambool Road

Penshurst-Warrnambool Road  Penshurst to the Princes Highway West 
Bridge Road  Bushfield to Caramut Road

Mailors Flat-Koroit Road  Warrnambool-Caramut Road to Penshurst-Warrnambool Road 
Bridgewater Road  Portland to Cape Bridgewater

Henty Highway to the South Australian border
Portland-Casterton Road  Princes Highway West to Glenelg Highway

Works are weather dependent and can impact planned schedules, with dates and locations having to change at short notice. We thank you for your patience.

The works will take place from 7am to 6pm, usually for a two-day period however this is dependent on the length of works. Signs will be placed at the start and finish of the works area to notify all motorists to reduce their speed to 40km/h. Access for driveways and intersections may be restricted for a maximum of five minutes each day while the crews move past. 

Once we have installed the rumble strips, we will refresh the line markings approximately 28 days later, with minimal delays expected.

If you’re travelling through the area, keep an eye out for our crew. During these works, we recommend that you plan ahead and allow a little more travel time. We’ll make every effort to minimise inconvenience to the community.
