For main roads, reserve sufficient footprint to integrate the corridor with adjacent topography (steeper sites need more space, flatter sites need less).
Benefits and considerations
- Allows a road to respond to its context more successfully
Example
The Princes Highway, north of Milton, varies to accommodate the changing terrain it traverses. Where elevation change is greatest (photo foreground) the batters below and above the carriageways are steeper. As the highway crosses the floodplain, the flatter topography allows an alignment nearer to existing grades.
