"The Rose Fitzgerald Kennedy Greenway, created during Boston’s “Big Dig” to bury its Central Artery, cost $40 million"

That's a lot of money for a vacant lot with a carousel. No one has ever reported the carbon footprint of the depressed highway and maintenance of the 'green space' (never mind ongoing costs). For the most part, the space is used exactly as it was before the highway was covered.

I think if they made these areas into real parks - trees, green grass, flowers, pedestrian pathways (no bikes, skateboards, etc.) quiet shaded benches, no boom boxes - it might be worth the cost.

But if they plan to convert them into “community centers,” only the derelicts, the jobless, and mobs of juveniles are going to show up.
