Duke Energy has been working for the past few months on a Grid Strengthening Project in which aged wood pole structures and associated overhead lines are being replaced.

The current project is along U.S. 421 from Madison to Versailles and while most of the work takes place on the side of the roadway, there have been some temporary lane closures.

Lew Middleton of Duke Energy corporate communications wasn’t aware of lane closure some motorists have experienced along U.S. 421, but said such adjustments are made in the interest of safety.

“Due to the margin of safety from the highway, the contractor may elect to close a lane,” said Middleton, who noted that Pike Electric is a contractor for the project.

Middleton said the work will “improve integrity and reliability of service to our Duke Energy customers in the area. Completion of this project ensures compliance with current distribution line standards.”

The work involves approximately 20.35 miles of lines located partially within the city of Madison and primarily within unincorporated Jefferson and Ripley counties.
