Engineering Marvel in North Dakota

Located in Grand Forks and opened in 2001, the Ralph Engelstad Arena is an engineering marvel. Its unique roof design is made up of wooden trusses that are the largest of their kind in the world. The arena serves as the home of the University of North Dakota's hockey team and also hosts other events such as concerts. The arena is adorned with intricate mosaics, marble floors, and chandeliers. The arena also boasts the world's largest HD video board. I found this place fascinating and a must-see for anyone interested in engineering and design.
