"Really, for the next four weeks or so, this building is theirs," Cowboys spokesman Brett Daniels said. "They work around us, we work around them. It's a great relationship, and they're very cooperative and everything, but it's theirs. And we got to get ready for the big day."
Work started within hours of Friday night's Cotton Bowl. The first truck filled with supplies and equipment rolled up at 6 a.m. Saturday.
"Structures have to start going up now to meet the time lines and be ready to go on Super Bowl Sunday," Daniels said.
Workers are putting up a security perimeter fence to surround the stadium and installing thousands of temporary seats inside.
"We'll have probably over 12,000 temporary seats that are being brought in for the Super Bowl," Daniels said. "In all the areas where traditionally we have our party pass, we'll have fixed seats for the Super Bowl."
"It'll be nonstop here pretty much for the next four weeks," he said.
Arlington is preparing to close some roads and reduce others near Cowboys Stadium beginning Jan. 17. You can see which roads are affected on a map at the city of Arlington's website.
