A few days ago I’ve seen that one new opened bridge (Peace Bridge) here in Calgary is (was) missing. So I went went out the weekend to collect the GPS data for that bridge. In the evening I wanted to put this data to OSM. But for sudden the bridge was in. Checking the history I found that I just a few minutes too late: Just 30 minutes before the data was captured by another user here in Calgary.

But I was able to add some more information to OSM.
