CENTER CITY (WPVI) -- The newest addition to Philadelphia's skyline is nearly complete.
The workers who created One Riverside put their signatures on an 18 foot beam that will be a part of a topping off ceremony.
They were then treated to lunch by One Riverside developer, Carl Dranoff.
The 22 story glass luxury condominium tower offers spectacular views of the city in every direction.
The topping off ceremony will be held Wednesday night, on the 8th floor at One Riverside.
