At first glance, the route of one of America’s most controversial pipeline projects might not seem to have much to do with New England. What is the Constitution Pipeline? The Constitution Pipeline is being developed by Williams Companies, a large operator of pipelines across the United States. “Williams remains committed to advancing the Constitution Pipeline project and has submitted permit applications,” to regulators in New York and Pennsylvania, the company said in a statement this month. In May, the Wall Street Journal reported that the resurrection of the Constitution Pipeline was linked to negotiations between the Trump administration and New York over the fate of another project, Empire Wind.
