A recently completed project has recommended changes to the Austroads Guide to Road Tunnels Part 2: Planning, Design and Commissioning to rationalise road signs on the approaches to tunnels, to divert over-height and dangerous goods vehicles approaching tunnel entrances.
Vehicles attempting to pass through tunnels that have not been designed to cater for them can damage infrastructure, create significant traffic congestion and, in some unfortunate circumstances, put other road users at risk.
Diverting these vehicles away from tunnels wherever possible is crucial to avoiding potentially serious and negative impacts.
The project report includes recommended signage designs and guidelines for the placement of signage on the roadway preceding a tunnel and along diversion routes.
The signage guidance is designed to better inform drivers of the risks and limitations of the clearance heights of their vehicles, and to enable the driver to clearly identify routes that avoid tunnels and their approaches.
The recommended updates to the Austroads Guide to Road Tunnels Part 2: Planning, Design and Commissioning have been approved by the Austroads Board. A minor edition update will be published by the end of the year.
