Video: Pittsburgh's Mellon Arena demolished
Slow lapse photography shows the demolition of American sports arena
The demolition of Pittsburgh’s Mellon Arena has been completed following almost six months of work, according to Pittsburgh Tribune Review.
The process required six separate demolition sessions to remove the dome-shaped roof.
The final step saw the cutting of the cantilever arm which held the building in place since its opening in 1961.
The Civic Auditorium was the first in the world to have a retractable roof, with six of the roof panels folding in two.
However, for the last decade of the arena’s use the roof was immobile, partially due to the scoreboard hanging from its centre.
