In December 2004 the NSW Minister for Roads announced a package worth over $30 million of road safety improvements for the Princes Highway. The aim of the package is to reduce the number and severity of crashes on the highway. A five-year road safety analysis between 1999 and 2003 has been undertaken over the length of the Princes Highway from 800m north to 200m south of its intersection with Sussex Inlet Road. The analysis identified I I reported accidents within this section of road, and found that accidents at the intersection account for almost half of the number of accidents reported. Therefore it is proposed to upgrade the intersection. This REF addresses the potential environmental impacts of the proposed upgrade.
