My son and I walked through it – a dizzying experience and lots of fun.

We figured the weight of the steel, 2″ thick, 14′ tall, 180 x 2 feet long (2 infinity shapes) x 0.283 lb/cubic inch, which computes to 20.5 tons. In other words, no one is about to pinch this. My first wild guess was 10 cars, or 20 tons. Not half bad. (US tons of 2,000lbs per, for the Englishmen reading this).
