MADISON ó The three utility companies planning a high-powered transmission line from the Madison area to Iowa have picked a preferred route that runs along existing highway and power line corridors rather than farms and fields.

The proposed 345-kilovolt Cardinal-Hickory Creek line would run along Highway 18-151 from the Cardinal electrical substation in Middleton, go west from Dodgeville to Montfort, head southwest to Cassville and then move south to the Hickory Creek substation near Dubuque, Iowa, the Wisconsin State Journal reported . American Transmission Co., ITC Midwest and Dairyland Power Cooperative are working together on the $500 million project. The preferred route is more than 100 miles long, while an alternate route would add 20 miles to the line, said Kaya Freiman, an ATC spokeswoman.

The project will improve the electric systemís reliability, provide economic benefits to utilities and consumers and support renewable energy, said the Midcontinent Independent System Operator, the regional electric grid operator. Opponents argue that the line and its tall towers would damage important conservation areas.
