Why SoFi Stadium's Field Is 100 Feet Underground

Why is SoFi Stadium's football field about 100 feet below ground? This stadium engineering breakdown shows how nearby LAX shaped a project with a widely reported price tag of around $5 billion. A massive roof, a 2.2-million-pound video board, and a football field that can make room for international soccer. At SoFi Stadium in Inglewood, California, each design choice solves a different problem. In this video, we'll break down: Why airport height limits pushed the field underground. How the translucent ETFE roof lets in daylight and supports natural ventilation. How Samsung's dual-sided Infinity Screen puts 70,000 square feet of 4K display above the action, and how its weight fits into the roof design. How separate structural systems help manage earthquake movement. How removable seating and natural grass helped the venue adapt for the 2026 FIFA World Cup. What's planned for LA28: temporary swimming pools and a shared Olympic opening ceremony in 2028. How Hollywood Park connects the stadium with homes, offices, entertainment, and public space. Home to the Los Angeles Rams and Los Angeles Chargers, SoFi brings architecture, civil engineering, and event planning together on a huge scale. We look at the decisions behind the spectacle and what it takes to switch between football, soccer, concerts, and future Olympic swimming. Which part would you want to see up close: the underground field, the giant screen, or the future Olympic pool setup?
