Drivers were advised to avoid Decatur Boulevard near Washington Avenue because of heavy flooding Tuesday morning.
The flooding was caused by a water main break around 8 a.m. Officials said the pipeline was installed in 1969 and was at the end of its life cycle.
"Anything can cause a break," says Damon Hodge with Las Vegas Water District. "It can be anything from the age of the pipe to the condition of the infrastructure."
Several businesses in the adjacent shopping center went without running water Tuesday, including Dotty's and Jack in the Box.
Dotty's, a gaming bar, was unable to serve food or alcohol.
Viva Dentist rescheduled about 20 appointments.
A laundromat didn't open and a hair salon closed early.
Southbound Decatur Boulevard was closed near the area as crews addressed the problem. A few businesses were affected after the water was turned off.
All roads were back open as of 10:30 a.m. Tuesday.
The water main is expected to be repaired as early as 10 p.m. Tuesday and the latest by Wednesday morning.
