Project background

In 2012, the Australian and NSW governments completed a long term strategic plan for the Bells Line of Road corridor to identify improvement works and set priorities for the next 20 years and beyond.

The plan recommended safety and traffic improvements for the existing route along the Bells Line of Road corridor. There were 10 identified sites for Bells Line of Road between Kurrajong Heights and Bell.
