Hello Ewrt1,

Not sure where you're getting your info, but the "13th Avenue" you added to the map here is neither named 13th Avenue nor is it actually open to vehicular traffic, nor following your indicated path directly across the train tracks. Likewise when I went to a recent Flames game at the Saddledome the parking lots you changed to construction area were open, with plenty of cars parked in 'em...

I've updated the area as per https://www.openstreetmap.org/changeset/149290769. If you know something I don't, please feel free to correct me.
