Latest news

Oct 2022 - Reopening of Galston Road

After several weeks and many hours of work, Galston Road will be reopened to motorists from 7pm Tuesday 11 October 2022.

The majority of works on Galston Road have been completed, and the road is now safe to reopen to traffic, however, there is still some remaining work to be finished. This work includes backfilling around concrete retaining walls, hydroseeding of a native seed mix, pavement works, further drainage works, and further shotcreting.

To minimise traffic disruptions and reduce safety risks to the workers and motorists, we need to carry out these works under a full road closure at night.

We will carry out these works on Galston Road from 8pm to 6am Wednesday 12 October to Friday 18 November 2022, weather permitting. The road will be reopened to traffic by 6am each morning. Please allow extra time for travel and follow the direction of signage and keep to speed limits.

Project information

Galston Road

Galston Road passes through Galston Gorge which is notorious for its steep inclines and multiple hairpin bends. Because of this, heavy vehicles and buses that are 7.5 metres in length or more are prohibited from entering Galston Gorge and considered overlength.

Heavy vehicles and buses that are 7.5 metres in length are subject to enforcement action under the Road Transport (Driver Licensing) Regulation 2008 Rule 104 and 106(2).

Light vehicle combinations that include cars carrying trailers, boats or horse floats that exceed 7.5 metres are permitted to enter Galston Gorge. However, light vehicle combinations are reminded that vehicle combinations above 11 metres are unlikely to be able to navigating the tight bends in the Gorge based on recent surveys.

Rehabilitation of slopes in Galston Gorge 2022

We have created a factsheet that details what is involved with our current works rehabilitating the eight slippage sites at Galston Gorge.

Previous safety improvements

An increasing number of incidents over the past few years have resulted in Transport for NSW implementing several measures to improve safety on Galston Road and deter over length heavy vehicles and buses from entering the Gorge.

Multiple signs have been installed on both sides of the Gorge along with a vehicle detection system and vehicle activated variable message signs (VMS). These signs will be updated to advise motorists that light vehicle combinations over 7.5 metres are not affected.

These measures have helped to substantially lower the number of overlength heavy vehicles and buses using the corridor to avoid Pennant Hills Road.

Additional improvements were implemented for both sides of Galston Gorge building on previous work to improve the road for motorists and the community.

Key upgrades

Galston Road upgrades include:

  • Improving and supplementing the existing infrastructure at both ends of Galston Gorge by installing a camera based detection system
  • Providing a safe U-turn bay on the eastern side of the Gorge, between Ryan Trail and Evans Road
  • Slope and drain improvements on Galston Road between Calderwood Road and Berowra Creek
  • Safety improvements at the bend of Galston Road, starting 150 metres west of Montview Parade.
