The pipeline was proposed in 2011[3][4] and approved for construction in 2013 at an original cost estimate of US$86.6 million.[5] As of July 2014, construction was underway, and the costs continued to balloon.[5]

Construction was completed in April 2017.[1]


The pipeline has encountered fierce opposition through every stage.[6] In March 2018, an independent review of the pipeline's construction methods was ordered.[7] In January 2021, Vermont state regulators said the owner Vermont Gas failed to comply with its permit and did not follow construction standards.[8]
