It has been one of the league's glittering jewels for 36 years. But even Arrowhead Stadium, the home of the Kansas City Chiefs, can use a little repair and renovation work. When completed (and that won't be until 2010), the Arrowhead project will include a doubling of concourse space, 50 percent more concession stands, 80 percent more restrooms, new video boards and glitzy new suite, club and lounge areas.
