Just in regards to highways, as we have seen the weaving that we are starting to see because of permafrost and also we are starting to see a lot more sloping, sliding along the hillsides and also in regards to the effects it is having on our infrastructure. As a department, is there anything that is being done to find ways to mitigate some of these challenges? In the past we used to use permafrost. It worked for us by way of building on top of it and building layers over top. We are starting to see that with the temperature changes it is having an effect on world conditions, especially in the northern parts of the Territories. We are especially seeing it on the Dempster in regards to the challenges we are seeing by way of wash roads and whatnot. Are there studies or anything being done to try to mitigate this problem that we are seeing on our highways?
