Three local malls owned by Simon Property Group are trimming their operating hours.
Starting March 2, Century III, Ross Park and South Hills Village malls will close at 9 p.m. instead of 9:30 p.m.
The malls will continue to open at 10 a.m. Current Sunday hours of 11 a.m. to 6 p.m. will be unaffected.
According to its Web site, Ross Park already is closing at 9 p.m.
Simon spokesman Les Morris said the change was made for a combination of reasons. One was that some mall anchors already were closing at 9 p.m. Malls in other parts of the country also had gone to an earlier closing, he said.
"From a traffic standpoint, it just seemed to be the thing to do," he said. "We've been looking at this. Some stores wanted it. In other areas, a 9 p.m. closing is more common than not."
