A major downtown intersection will be kept closed through at least Thursday evening as crews work to repair a 15-foot sinkhole, according to city officials.
The intersection of 14th and F Streets Northwest was closed Tuesday. An investigator from D.C. Water utility discovered that concrete had fallen onto and collapsed a 54-inch sewer line below it.
D.C. Water officials said Wednesday that crews are working around the clock to fix the 116-year-old brick sewer line but had no estimate of when the repairs would be complete. It was estimated that about 30 feet of the sewer will need to be excavated and repaired.
A District Department of Transportation spokeswoman said road closures are likely through the Thursday evening rush hour if not longer but cautioned there is no firm time line for streets to reopen. Closed is 14th Street Northwest from New York Avenue to Pennsylvania Avenue, and F Street Northwest from 13th to 15th streets.
A number of utility lines as well as a set of old trolley tracks run over the sewer line, complicating the repair process, D.C. Water officials said.
