It looks like the Flatbush Avenue crane has been disassembled (updated)

Bottom, a photo sent to me yesterday shows that the Flatbush Avenue crane needed for the green roof is gone, meeting the most optimistic schedule. Note the previous Construction Alert:

The Flatbush Avenue crane was assembled the weekend of May 16-17. It will be needed for approximately 2 to 4 weeks (depending on weather conditions), after which it will be disassembled.

So it's certainly good for traffic--at least when full passage along Flatbush is restored. (Updated below, with photo today: it has been restored.) Was the effort to get the crane out why they were working on the weekend?
