This pie-in-the-sky plan does not rate serious consideration. (P-G, Edit Board)
A few notes:
1) The editorial's most compelling-sounding point is that the arena separates the neighborhood from Downtown. That was certainly true of its genesis, but now there is the enormous matter of the Crosstown Expressway, including its complex intersection with Bigelow Boulevard. Any "reconnection" would take a lot more that extending Wylie Ave. through where the arena presently stands and a simple traffic light. That's the fearsome challenge.
2) I get zero impression that Penguins ownership is interested in undertaking an ambitious infrastructure extension and reconnection over its developable plot of land anyway.
3) The editorial also points out that Pfaffman doesn't have developers and financing lined up; well, the Penguins and the City have only just hired their planners. It's extremely early.
4) And it doesn't give the barest nod in the direction of the merits of creative re-use for significant and unique structures in general, let alone seem to appreciate the full import of the word "creative". It just sacks the idea with maximum authority, in the name of "getting the most money" for the Sports & Exhibition Authority.
