I drive past the gash in the ground between Front and Rogers Centre every day and it cries out to be covered up. But I'm not getting the price tag part.
Why does it take a billion $ to deck over a half mile of railway cutting? They're doing it further west at Liberty Village with no suggestion of a massive cost. They also decked over part of the Yonge St subway decades ago.
Is it the structural requirement of adding dirt to make a park? If so, why not deck over the cut with wood or concrete and make the area into tennis courts and hockey rinks?
