FIFA Fan Festival reached capacity roughly four hours before the start of the World Cup Round of 16 match between Mexico and England on Sunday.
The event temporarily paused entry upon reaching its capacity threshold and would reopen gates after more space cleared. The event has a 7,500 person limit.
FIFA posted about the capacity alert shortly after 3 p.m., and the match is set to kick off at 7 p.m. central time.
“What an incredible turnout today, Houston!” FIFA wrote on social media.
Hundreds of soccer fans were lining up outside the Polk Street entrance for FIFA Fan Festival before 2 p.m. Across the street, gates have opened for a free watch party that will air the high-stakes match taking place in Mexico City.
