The newest World Trade Center family member, 3 WTC, is expected to open Monday, in what has been a 10-year wait since Silverstein Properties first broke ground at the site.

Larry Silverstein, whose firm developed the 80-story tower, will cut the ribbon in front of the building early next week, according to the New York Post.

Construction on the $2.4 billion tower, which offers views of four states from the top and holds more than 2.5 million square feet, underwent several delays, including a vote that was tabled several times by the Port Authority of New York and New Jersey to grant a $1.2 billion subsidy for the project in 2014.

Designed by the Pritzker Prize-winning architect Sir Richard Rogers, the building features a 60-foot-high lobby ceiling and office floor plates of up to 60,000 square feet.

In March, Silverstein’s leasing head Jeremy Moss told The Real Deal that the building was 40 percent leased and asking prices range from the $70s to $90 per square foot. GroupM, the media investment firm, is the anchor tenant, and consulting firm McKinsey and Co. recently signed for three floors. [NYP] — David Jeans
