(Note that there was no explanation why there was so little notice, especially given that it's a claimed "routine inspection." Nor did this come from a government entity.)
As part of the installation of a green roof on Barclays Center, a construction crane located on Sixth Avenue will be temporarily disassembled for routine inspection, requiring the temporary, and intermittent closure of Dean Street between Flatbush and Sixth Avenues and Sixth Avenue between Pacific and Bergen Streets.
Flagmen and/or Traffic Enforcement Agents will be provided to assist with vehicular and pedestrian detours, as will Variable Message Signs. Sidewalks in work zone areas will remain open only to residents and visitors.
