Can I just add one more example from Alberta?
I don't have all the details. This was written to me by Molly Douglass, who's the reeve of the County of Newell around the Brooks area of Alberta. If you know the geography of Alberta, it's on Highway 1 between Medicine Hat and Calgary. This had to do with an old bridge structure over a canal. Often culverts are more effective than bridgeworks and they're less expensive to put in as well. Just as Dave mentioned, when NWPA got finished with them, they wanted a sufficiently large culvert so a canoeist could go in sitting upright. It didn't make sense in this case because it's not navigable water; nobody is allowed to be in that area. It's on the Fisher Bridge, which was discussed for replacement. By the time the NWPA got finished with it, the cost had increased by $500,000 and they still haven't built the bridge. And that was in 2003.
