Clearing is expected to begin later this month on a nonprofit cooperative’s efforts to string 6.2 miles of new, updated power lines across North Hall County, including a small part of Lake Lanier. “We’ve surveyed (the route) and we’re working with the property owners,” said Craig A. Heighton, public affairs director for Tucker-based Georgia Transmission. The $5.5 million project is otherwise on track, with construction set to start early next year on 115,000-volt lines between Leach Road and an area off the lake between Ga. 60/Thompson Bridge Road and Riverside and Island drives.
