The Towerbirch pipeline project will include 55 km of 36-inch pipeline paralleling the existing NGTL Groundbirch Mainline, along with new meter stations, and expansion of one meter station. The majority of this projects scope will be within British Comumbia, with only a portion in Alberta.

Dinosaur bone fragments containing what is thought to be the remains of a Pachyrhinosaurus, were discovered on the Elmworth section of the 2021 NGTL System Expansion Project.
