Residents might want to put off any early morning travels along Hwy. 401 in Chatham-Kent on Sunday.
Hydro One says a section of the highway between Kent Bridge Rd. and Victoria Rd. will be closed from 5am-8am.
The planned closure is to address damaged power lines along the highway.
"Hydro One is stringing new power lines across the highway to replace equipment that was damaged by a storm earlier this year," says Hydro One. "For safety reasons, no traffic can travel under the wires as this work is in progress."
Detour routes will be in place.
