The first of two expansions came in 1974 when the east side upper deck was added, boosting the capacity to 20,000. The latest addition came in 1997 when the seating capacity was upped to 30,000. The $10 million renovation added seats in the southwest and southeast corners of the stadium.  A Hall of Fame for Bronco sports was also added. Today, Bronco Stadium is one of the best stadiums in the WAC conference. A two tier grandstand is located on both sides of the world’s only blue turf field and small sections of bleachers are located in each endzone. In addition to being home of the Broncos, the stadium hosts the annual Humanitarian Bowl each year.
