Interstate 77 from north of John Belk Freeway to south of Brookshire Boulevard is among the areas where most lights aren't working, the Observer reported in April. DOT said then that it would spend $51,000 to fix lights at some Charlotte interchanges that are outside active construction zones this summer.
Statewide, lighting fixtures will be switched to longer-lasting and lower-maintenance LED lights. The state expects to save more than $56 million in reduced costs for electricity and maintenance over 15 years.
More than 12,000 building lights, such as those at rest stops and weigh stations, will also be replaced. A new lighting and control system will support the maintenance of the lights and is expected to also save energy.
