We’ve noticed an increased number of heavy vehicles carrying dangerous goods attempting to travel in WestConnex tunnels - especially on the new Sydney Airport connection via Qantas Drive to the WestConnex M8 and M4.
While we monitor the motorway 24/7 and can assist customers when needed, placarded vehicles are not allowed in tunnels or on roads connecting to tunnels.
Dangerous goods like petrol, fertiliser, paint-tin contents, jerry cans and other liquid substances are very high-risk - if spilled, they cause an increased risk of serious accidents and can enter the tunnels' drainage systems, causing pollution.
To ensure tunnel safety, the following vehicles are not permitted in tunnels:
- Vehicles and loads exceeding 4.6m in height
- Vehicles carrying commercial quantities of dangerous goods
- Any vehicle displaying a dangerous goods placard
- Mopeds
- Tractors
Always take an alternate route that is available. For heavy vehicle travel in NSW, visit the National Heavy Vehicle Regulator website.
