To support electric reliability and increase capacity in the Ann Arbor area, ITC will construct approximately three miles of underground transmission line to connect the new Apex substation located near the intersection of Huron Parkway and Hubbard Road to the existing Phoenix substation located just north of Dhu Varren Road.

ITC recognizes the critical role that local residents, landowners and communities play in reviewing and hosting new electric transmission lines. ITC is committed to open, honest and frequent communications with landowners. We work respectfully with landowners throughout the design and construction process to identify possible routes for the project that minimize impacts to their properties.  

Open houses were held on November 9 & 10 at Washtenaw Community College. Thank you to the community members who attended and provided valuable input. If you still wish to provide feedback, please take our project survey.
