New camera technology has been switched on today in an effort to improve heavy vehicle safety at Galston Gorge.

The cameras have been installed near Montview Parade at Hornsby Heights and Calderwood Road at Galston, to measure the length of heavy vehicles.


  • The maximum length for heavy vehicles to travel through Galston Gorge is 7.5m
  • Trucks that exceed this length will incur an on the spot fine of $2270
  • Drivers of heavy vehicles that get stuck will incur the following penalties;
    • License and vehicle registration suspended for up to three months
    • Fined a maximum of $3740 and lose six demerit points

Cameras were installed along with an “Over Dimension Measurement” device, using infrared and a radar-based technology measure the length of vehicles.

Minister for Roads Maritime and Freight Melinda Pavey said the technology would reduce the number of vehicles stuck in the Gorge, and improve safety and time savings for motorists.

“Over-length trucks trapped in Galston Gorge cause detours of more than 30 minutes for other motorists,” Mrs Pavey said.

“With almost 100 over length heavy vehicles trapped in Galston Gorge over the past year, the impact on the road network has been significant.”

Member for Hornsby Matt Kean said the NSW Police, emergency services and motorists are all impacted by over length incidents in the Gorge.

“It is crucial that this technology is used to deter drivers who attempt to use over-length vehicles and improve journey reliability for all motorists,” Mr Kean said.

Galston Gorge is a vital link for vehicles travelling on the Pacific Highway north of Sydney to the western suburbs.
