Construction began on this residential skyscraper in 2013 and reached completion in 2016 after topping out at 715 ft. UBS began constructing shed and installing hoists in January of 2014. This job sported three sidewalk bridges throughout the site. One sidewalk bridge on 56th street ran 16 ft high and a 130 ft long with two high sections and truck gates.
