The Rock Island Clean Line is in the process of determining a route for the transmission line and is partnering with stakeholders, including communities, individual landowners, state and federal agencies, and other interested parties in the siting of the project. We have narrowed the potential location for the project through the following process: project area, study corridor, alternative route corridors, and preferred routes. In Illinois, after more than two and a half years of work, the Rock Island Clean Line has identified a preferred route and an alternative route. For more information, please see below. In Iowa, environmental and engineering studies for potential routes are ongoing.
A study corridor is a 3-10 mile wide area in which routing criteria and public input are reviewed in the process of determining alternative route corridors for the transmission line. The Rock Island Clean Line study corridor is identified in green below.
An alternative route corridor is an approximately half-mile-wide area in which routing criteria and public input are reviewed in the process of determining preferred routes for the transmission line. The Illinois alternative route corridors are identified in dark grey below.
The determination of alternative route corridors is not part of the regulatory process in Iowa; environmental and engineering studies for potential routes are ongoing.
