The installation of heavy vehicle speed cameras on the highway at both ends of Victoria Pass should be completed by July, according to the latest community update from the Roads and Maritime Services.
The project was first announced by the NSW government in October 2012.
The RMS update confirmed the project includes installation of a retaining wall at the top of Victoria Pass, two point-to-point speed cameras, variable message signs and safety barriers.
Point-to-point speed cameras record the amount of time it takes a heavy vehicle to drive a certain distance and then calculate the vehicle's average speed.
The $1.8 million project is funded by the NSW government.
