Repair crews worked through the evening to repair a water main in Crystal City that broke just after the morning rush hour.
A water main break in Arlington shut down water to five office buildings and one apartment building in the Crystal City area Friday.
Arlington County's Chief Building Official Shahriar Amiri ordered the shutdown of the Boeing Co.'s Crystal City construction site, located near 10th Street S. and S. Ball Street.
NBC4's Melissa Mollet reports that it was apparently a 12" pipe that burst. The cause is unknown at this point.
Water has now been restored to all the affected buildings.
