I am currently fixing up Highway #16 in Alberta Canada to match both the saved tracks and NRN data. I will be working on Highway 2, 41, 2a, 1a and 1 over the next few weeks as well.

Looking for a few Canucks to try out a new website I put together to help with fixing the Canadian maps. The site is very new so be gentle. :)
The site examines the OSM data (Alberta maps for now) for various problems like missing NRN data, broken links between roads and zero length ways. It's only on Alberta for now but the intent is to get to all of Canada at some point.

Please try it out at http://osmfixcanada.ca and send me feedback.

Cheers.
