The 53 story Aria on the Bay is close to topping out and is currently on the 52nd floor of construction. 

Almost a year ago, the building was just starting to go vertical.

Aria on the Bay is being developed by Melo Group, who are also developing the under construction Square Station and was designed by Arquitectonica. The building will have 647 residential units and 40,000 square feet of retail and office space.
