Here are 2 pics of the logical(?) city planning. Notice the posts along the side of the roads?
These pointy ones are supposed to represent harpoons (well the device that hold the harpoon gun in assume) and mark out where the 'sidewalk' is - if there actually was one.
These more rounded one are supposed to mark out where a crosswalk would be. An interesting note there - here In Iqaluit the pedestrian is given the right of way always! All you have to do is stand along the side of the road (anywhere - begging, middle, end) and all the cars stop and let you cross. As a result not many people actually use the 'crosswalks' and cross pretty much willy nilly as they feel like.
I've included this pic to show what the tundra in the town is typically like. As you can see there are NO tree's and it is very rocky! - Yo Adrain!!!
