Mark Twain Transmission Project

Open House Information

The proposed new route will run through Adair, Knox, Lewis, Marion and Schuyler counties and includes construction of the Zachary Substation near Kirksville, Missouri. It will use nearly 90 percent of existing right of way on Northeast Power’s 161 kV line between Palmyra and Kirksville and Ameren Missouri’s 161 kV line from Kirksville to the Iowa border. The new route will minimize impact to landowners, communities and existing farm land, and result in fewer utility structures along the existing right of way. New right of way will be sought in Adair County to connect the Zachary and Adair substations and in Marion County to connect to the Maywood Substation. Additionally, 50 feet of expanded right of way is needed along the Ameren Missouri line in Adair, Marion and Schuyler counties.
