Gas Transmission Northwest (GTN) is a 1,377-mile (2,216-km) pipeline system that transports Canadian natural gas to communities in Washington, Idaho, Oregon and California.

The Western Path Delivery project would potentially supply natural gas to southwest Alberta and connected downstream markets with natural gas produced in Western Canada.

Pump stations are built at strategic points along a pipeline to maintain a constant flow of oil at a walking-pace speed. Learn more about them here.
