Crews were out in Park Slope Saturday morning to help repair a water main that burst overnight.
Fire officials say the main broke just after 7 p.m., sending water spilling onto Flatbush Avenue.
Officials say no one was injured, but the situation created traffic delays as the evening commute was wrapping up.
The street was originally blocked off in both directions, prompting buses to be rerouted, but it has since been reopened to bus routes.
