The right lane of Nicholasville Road near Central Baptist Hospital remained closed Friday as crews worked to repair an overnight water leak.
Repairs were expected to take most of the day, according to the Lexington Traffic Management Center.
The leak on Shady Lane near Nicholasville Road was one of two that occurred overnight.
The other occurred a few blocks away on Rosemont Garden, where an eight-inch water line running under the railroad tracks began leaking about midnight, said Susan Lancho, spokeswoman for the Kentucky-American Water Co.
Never miss a local story.
The basement of at least one home was flooded, she said.
There was a report of as much as six feet of water in the basement, but Lancho said she didn't know the extent of the flooding.
The problem on Shady Lane involved a water valve that began leaking, she said.
Lancho said it wasn't known whether the passing of trains might have triggered the Rosemont Garden leak. There was no indication that the Rosemont Garden leak and the one on Shady Lane were related, she said.
Water service was restored by Friday morning, although one home in the Rosemont Garden area might be without water, Lancho said.
Permanent repairs will be scheduled, she said, and work on Rosemont Garden will have to be coordinated with the railroad, because digging under the tracks will be involved.
