Trestle bridge under construction at LNG site – Kitimat Northern Sentinel





Trestle bridge under construction at the LNG site

The bridge is expected to be completed in December 2022.




LNG Canada is installing a bridge that will transfer liquefied natural gas (LNG) from storage tanks to tankers. The bridge will support the cryogenic pipes that will carry the LNG from the storage tank to the berth.

The trestle design has some advantages for the nearby estuary.

“For the most part, everything is done on the ground to keep the migration corridors open for the different animals,” said marine construction engineer Alex Benko.

The cantilever bridge that builds the trestle never touches the ground. He drives stakes on his way and uses them as an anchor point to move forward. Using this particular method reduces the footprint on the nearby estuary as the only thing touching it are the piles.

A pile is a post-shaped foundation, usually a cylinder, that is driven into the ground to provide support for structures built on it.

The bridge is built near the mouth of the Kitimat River. The estuary is located at the southeast corner of the site. The bridge will also support a causeway allowing maintenance workers to access the pipes without disturbing the estuary.

Piling is in progress and a causeway is added to the bridge. A foundation is also added for where the pre-assembled pipe supports will be placed.

The bridge is expected to be completed in December 2022.
