when did the roof collapse at the metrodome
Hubert H. Humphrey Metrodome A severe winter storm arrived on December 10–11, 2010, with over 17 inches (43 cm) of snow accumulation, and strong winds; those winds made the roof unsafe for the snow removal crew. As the workers were pulled back, the roof was already sagging in the center. On December 12 at about 5:00 a.m., the roof had a catastrophic collapse as three panels tore open. The night before, a Fox Sports crew setting up for an upcoming Vikings game noticed water leaking from the roof and kept their cameras on all night; those cameras captured the roof tearing and ice and snow falling into the stadium.[40][48] No one was injured. Most of the roof sagged and came to rest on cable stays. The collapse caused no damage inside the stadium aside from a light fixture and some seats. The turf was not damaged; a drainage system designed for cleaning purposes allowed the field to dry out.[49] On December 15, 2010, a fourth panel ripped open, sending more snow and ice into the dome.[50]
Sydney Opera House The Fort Macquarie Tram Depot, occupying the site at the time of these plans, was demolished in 1958 and construction began in March 1959. It was built in three stages: stage I (1959–1963) consisted of building the upper podium; stage II (1963–1967) the construction of the outer shells; stage III (1967–1973) interior design and construction.
