I just ran into this very interesting article at Uni-Watch. We all know that Forbes Field was replaced by Three Rivers Stadium, but did you know that there was a proposal to build a stadium on a bridge across the Monongahela River? That is pretty amazing in my opinion.
The benefits of the proposal included the thought that land acquisition would have been minimal and it would have reduced property tax losses. The proposal included more than a stadium. It boasted the world's largest covered boat dock, a six hundred room hotel with "gourmet restaurants", one hundred air conditioned bowling alleys, and beautiful gardens overlooking the river. The plans were drawn up by an architect from Paris, France.
I don't have any information about why it wasn't built. But I guess it's a safe bet to assume that it just wasn't feasible from an engineering or financial perspective. I just wanted to share this. I think it would be interesting to anybody who has followed the Pirates or Steelers or just has an interest in the history of Pittsburgh and ballparks.
