Deh Cho Bridge
When I used to work in Canada for Infinity Engineering a big project was the Deh Cho Bridge. I left before they started to erect the bridge. My work mates send me some pictures, pretty cool to see the thing standing up :-).
The bridge is about 1000 m long with a main span of 190 m or so. On the picture below they are just about to close the main span.
Bridge Closure, big day!
When I was working for Infinity I wrote a Paper, The Northern Link, so if you want to learn more about it check it out. There is also a page with a lot of pictures of the Department of Transportation of the Northwest Territories.
