The Prince Rupert Gas Transmission project planned for north-central B.C. is taking particular care to avoid sensitive environmental areas along the route. When crossing streams and rivers, various methods are used to cross that don’t disturb the fish or habitat, including HDD or Horizontal Directional Drilling that allows the pipe to pass under a river without affecting the watercourse. This video, produced in 2013, traces one of the methods TransCanada used to re-establish riverbed support under a pair of natural gas pipelines that cross the Pend Oreille River, near Bonner County, Idaho, in the U.S. Pacific Northwest.
The video also explains TransCanada’s commitment to ensuring the river’s fish habitat was enhanced during and after construction.
