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 $16 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. The arena was largely shuttered after the Nuggets and Avalanche moved to Pepsi Center.
