Challenge

This major State Highway upgrade (part of the "Roads of National Significance") utilises the Public Private Partnership (PPP) contract model and requires colossal earthworks and Greenfields road construction over a 20km+ length. Most site access is conducted off State Highway 1 and with volumes above 20,000 vehicles per day on regular occasions - safety is critical - complex geometric and site-specific signage solutions were necessary.

Solution

Parallaxx provided all initial TMP design to get the project up and running and a number of complex site access designs along State Highway 1 involving geometric changes and unique electronic signage that utilised on-road triggers to activate.

Results

The project is a long one - not plotted for completion until late 2021. Initial site access designs needed to stand the test of time and volume - permanent linemarking and barriers were used to ensure minimal maintenance and robust safety standards for the duration. The project is operating well.
