Silver poles appearing around Roanoke, so what are they?

Several viewers wanted to know what those big silver poles popping up all around Roanoke are, and we found out for you.

They are transmission lines protecting your power.

Appalachian Power is putting them up to carry six miles of lines so existing power stations won't be overloaded.

The $15 million project is a response to growing electrical use in Roanoke since the last transmission line was built in 1994.
