A new route is being proposed for the Mark Twain Transmission Project (Project), a 345,000-volt transmission line and substation to be built in northeast Missouri. After listening to community members, landowners, county commissioners and other local and state representatives, Ameren Transmission Company of IIllinois (ATXI) is collaborating with Northeast Missouri Electric Power Cooperative (Northeast Power) and Ameren Missouri to use existing right of way for the majority of the new approximately 100-mile line.
The proposed new route will run through Adair, Knox, Lewis, Marion and Schuyler counties and will include construction of the Zachary Substation near Kirksville, Missouri. To minimize the potential impacts of the Project and to address concerns of property owners and local communities, the proposed route will use nearly 90 percent of existing right of way on Northeast Power's 161,000-volt line between Palmyra and Kirksville and Ameren Missouri's 161,000-volt line from Kirksville to the Iowa border. After reviewing the proposed new route, the Adair County Commission asked ATXI to consider reconfiguring a portion of the route that runs through Adair County. As a result, we are seeking input on five route options in the area south of Kirksville. The route options include relocation of the new substation adjacent to the existing Adair substation. We are seeking feedback from landowners in all five counties along the proposed route.
