Metropolitan Utilities District crews are on the scene after a 12-inch water main broke at 72nd and Pinkney Streets Thursday afternoon.
Water was gushing out of several breaks in the pavement, forcing Omaha police to shut down north and southbound lanes.
About 30 homes and 10 businesses are affected. Repairs will be completed and service restored Thursday night.
Traffic is now restricted to one northbound and one southbound lane on 72nd Street.
