Canary: "Minnesota takes rare step to allow power lines alongside highways." Other states have taken this action or are contemplating it, including Wisconsin, Iowa, California, Washington, Oregon, Maine, New Hampshire. "But states have been slow to shift from long-standing policies that aim to keep highway rights-of-way clear of other infrastructure that could compromise safety, burden transportation departments with unforeseen costs, or restrict the option of expanding highways in the future." In Minnesota, the chief forum for transmission expansions runs through the Midcontinent Independent System Operator (MISO), the grid operator for all or part of 15 U.S. states and Canada’s Manitoba province."NextGen Highways is also lobbying for federal legislation that could support state efforts to site transmission along highways."
