Mayor Michael Bloomberg says the dangling boom of a midtown Manhattan crane damaged in the storm has been tethered to the luxury high-rise building.
Bloomberg said that officials hope to open 57th Street on Saturday night.
The crane boom collapsed during Superstorm Sandy this week, likely because of heavy winds.
Engineers climbed the 74-story building in the midst of the storm to inspect the crane.
Some neighboring buildings were evacuated, including a hotel with 900 guests.
