The Cushing interchange is currently undergoing an expansion project, which will add pipelines to the existing hub.
One new pipeline is already in operation, with another close to completion and one more major project to be announced later this month.
Tulsa-based NGL Energy Partners have teamed up with Rimrock Midstream to create the Grand Mesa Pipeline.
The Grand Mesa will be open to oil producer commitments shortly and will be a 550-mile system from Weld County, Colorado, to the Cushing hub.
Flanagan South, once operational in the coming weeks, will run 600 miles and carry up to 600,000 barrels per day. The new pipeline runs along a similar route to Enbridge's existing Spearhead system from the Flanagan, Illinois, terminal to Cushing.
