McNichols Sports Arena (aka Big Mac) was an indoor arena in Denver, Colorado, USA, adjacent to Mile High Stadium. Completed in 1975 at a cost of $10 million, it seated 16,061 for hockey games or 17,171 for basketball games and contained 27 luxury suites. The arena was largely shuttered after the Nuggets and Avalanche moved to Pepsi Center and was razed in 1999 to make space for a parking lot surrounding INVESCO Field at Mile High.
