Riverside Drive is closed between Lancaster Avenue and the I-30 eastbound ramp, a city water official said early Tuesday.
Repairs to a 12-inch line that broke Monday were completed, but the road was still being repaired, said Mary Gugliuzza, city Water Department spokeswoman.
Motorists who need to access I-30 eastbound should use the Beach Street ramp.
Gugliuzza said the section of Riverside Drive likely will be closed until sometime Thursday.
