A "portion of time": Dean Street between Flatbush-Sixth will be closed Mon.-Fri. from 9 am to 3 pm for B2 work
That was hinted at, though not fully. In the official two-week Atlantic Yards Construction Alert issued earlier in the week, Empire State Development, channeling developer Forest City, said:
We have not been advised by Con Edison regarding the duration, but it is anticipated to take 2-3 days to complete their work. We are assuming that Dean Street may have to be closed between 6th and Flatbush for a portion of time to complete their work.
