TIMELINE: HUBERT H. HUMPHREY METRODOME

1979

• Construction on the Metrodome began on Dec. 20. The stadium was funded by a limited hotel-motel and liquor tax, local business donations and payments within a special tax district near the stadium site.

1980

• In January, bulldozers encounter a 250,000-pound piece of granite. It's moved to Plymouth and dubbed "Plymouth Rock."

1981

• In October, the Dome is inflated. But in November, the roof collapses under 10 inches of snow.

1982

• The Metrodome opens, replacing Metropolitan Stadium in Bloomington and Memorial Stadium at the University of Minnesota. Building cost was $68 million--about $2 million under budget. The name was in memory of former Minneapolis mayor and U.S. Vice President Hubert Humphrey. The Twins play their first game there on April 6.

• In December, the Dome roof falls after snow slides against a large snow-removal bucket and a resulting 3-foot gash grows.

1983

• In April, wet, heavy snow deflates the roof; four-day repair results in postponement of a baseball game.

1986

• An April Twins-Angels game is halted briefly when high winds rip two holes in the Dome's inner roof.

2009
