CapX2020 Hampton-Rochester-La Crosse 345 kV project

The Hampton-Rochester-La Crosse transmission line will improve reliability for the Twin Cities, Rochester and La Crosse areas, including rural electric cooperative customers in Goodhue, Olmsted and Wabasha Counties of Minnesota and Buffalo, Trempealeau and La Crosse Counties in Wisconsin. 

345 kV poles are typically between 140 and 170 tall and will be between 700 and 1,000 feet apart. Typically, a 150-foot right-of-way will be required. The project is expected to be finished in 2015.
