The Madison Water Utility says a water main break has partially closed East Gorham Street downtown, and repairs may take most of the morning.

The utility said a six inch main in the 1200 block of East Gorham Street gave way around 4 a.m. Wednesday, and utility workers started working on the main break about 4:30 a.m.

Because of the repairs, Gorham between Baldwin Street and Few Street will remain closed until at least noon Wednesday.

The utility believes around a dozen residents on the east side are without water because of the break.
