Athletics’ Las Vegas Stadium Reaches Major Construction Milestone

First 200-Ton Roof Truss Installed at Athletics’ Las Vegas Stadium

The Athletics’ future home in Las Vegas has reached a major construction milestone. Crews lifted the first 200-ton arch truss segment into place, marking the start of roof construction on the 33,000-seat Major League Baseball ballpark.

Thornton Tomasetti is serving as structural engineer for the stadium, working in collaboration with the design team of Bjarke Ingels Group (BIG) and HNTB. A Mortenson-McCarthy joint venture is the construction manager.

Long-Span Steel Roof Advances on 33,000-Seat MLB Ballpark

The stadium’s long-span roof features five overlapping curved surfaces designed to look like baseball pennants, supported on freestanding steel arch trusses that will span nearly 700 feet across the playing field.

The roof structure will reach 290 feet above the playing field.

Cable-Net Glass Façade Will Frame Views of the Las Vegas Strip

The ballpark will also feature one of the world’s largest cable-net glass façades in the outfield, which will provide expansive views of the Las Vegas Strip.

Thornton Tomasetti’s Role

In addition to structural design, Thornton Tomasetti is providing:

• Construction engineering
• Façade engineering
• Connection detailing
• Waterproofing
• Façade access services 

The stadium is scheduled to open for the 2028 baseball season.
