On Thursday, Feb. 8, a “topping out” ceremony was held at the USTA Billie Jean King National Tennis Center, as the final steel beam of the new Louis Armstrong Stadium’s roof structure was lifted into place.

Construction firm AECOM Hunt, which also built the roof on neighboring Arthur Ashe Stadium, also is managing the Armstrong Stadium project, and many of the workers on the project signed their names to the beam before it was hoisted to its permanent spot at the top of the new structure.

The new 14,000-seat Louis Armstrong Stadium will debut at the 2018 US Open, giving the tournament two roofed stadiums, allowing for continuous play regardless of the weather.

The completion of Louis Armstrong Stadium represents the final piece of the USTA’s five-year transformation of the grounds of the NTC; a transformation that ensures that the site of the US Open will retain its place among the greatest and most fan-friendly sports venues in the world.
