The pipeline is based not just in the United States but in Canada as well, which was established in 2010 and is one of the most controversial pipelines currently in existence. While it was initially unremarkable and gained little attention, it was when the fourth phase of the pipeline was going to be established, known as Keystone XL, this gained a lot of opposition from environmentalists in the country, which led to President Obama delaying it in 2015, though President Trump unsurprisingly in 2017 began action which would enable the pipeline to be established.

Easily topping the list of the 15 longest pipelines in the US is Cochin Pipeline, which actually commenced operations back in 1979. While it initially transferred commodities from Illinois to Fort Saskatchewan, however, the route was reversed in 2014 and the new route has been followed since.
