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, 17,171, for basketball games and contained 27 luxury suites, which were installed as part of the 1986 renovation. It was named after the mayor of Denver, William (Bill) H. McNichols, Jr., who served from 1968 to 1983. A small scale scandal was created when the arena was named after a sitting mayor.
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.
