TIMELINE: HUBERT H. HUMPHREY METRODOME

• 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.

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

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.
