Most of the existing structures and components along this 21.5-mile line corridor have been in service for nearly five decades. To maintain reliability for our customers and due to the age of some components, the line is being replaced. The line was primarily built on wooden H-frame structures. In some locations, it also used brown, weathering steel lattice structures and monopole structures.

We are replacing the double circuit weathering-steel lattice structures primarily with brown, weathering-steel monopoles. The single circuit wooden H-frame structures are being replaced with brown, weathering steel H-frame structures with galvanized cross arms and x-braces.
