The exact details of how we will construct the road and finalize the design over the top of those 12 kilometres are still to be determined. We have built in some assumptions about what we’re going to do about that. Additional fill or insulation are two of the most common ways to mitigate, so there is an allowance for those. But we
do, as part of the detailed design, need to confirm exactly the conditions and then we will finalize the design.
