DETROIT A power outage has shut down Detroit's City Hall, several courts, a federal building, parts of a college campus and an art museum.
City spokesman Bob Warfield says extreme heat, cable failure and maintenance work combined Wednesday afternoon to cause an overload.
Authorities are asking customers not to turn on air conditioners or other non-essential appliances. Warfield says institutional customers are affected by the outage and that residents are on a separate system.
The Frank Murphy Hall of Justice and 36th District Court were evacuated after their courtrooms were left in the dark. The McNamara federal building and Detroit Institute of Arts were without power. Wayne State University cancelled some classes.
The downtown above-ground People Mover rail also stopped running.
