For about 20 years, the Alberta oilsands were the largest construction project in the world. Numerous huge steel fabrication yards were built located near the Edmonton airport o support this construction.  These yards built huge fabricated steel modules that were taken north via truck. Most of these loads were classed as "oversize loads." There are over size loads in all provinces and then there is Alberta. I worked for decades in heavy industry in the three western provinces and was stunned to see what can be transported on Alberta highways.  

As the last mega oillsands project is wrapping up (Suncor's Fort Hills) these yards are looking for work.

Unfortunately there are about 1,500 miles of mountains between Edmonton and the BC LNG sites.
