The $420 million transmission line that will stretch across northwestern Wisconsin is about 40 percent complete.
The Arrowhead-Weston transmission line runs from the Wausau area to Duluth, Minnesota. It should be ready to go by 2008.
Its owner and operator is American Transmission Company. ATC executive Mark Williamson says the Citizen's Utility Board's recent criticism about design flaws are unfounded. He says the group's concerns are based on a "flawed" analysis that was already investigated.
