If you've ever spent any time on New York City's finest roadway, the Brooklyn Queens Expressway, garden is not one of the first words that comes to mind. That could change on one particular strip in Brooklyn if a concept -- which you see above -- gets approved and built. The concept is part of a project calling for solutions to a trench that runs from Carroll Gardens to the Columbia Street Waterfront in Brooklyn. Starr Whitehouse Landscape architects floated three possible solutions for improving the stretch, which would cost between about $10 and $18 million, very cheap in comparison to other projects of this type. The Green Canopy proposal calls for a massive plant covered canopy with solar panels to stretch over top of the entire area making it self-sustaining and reducing noise in the area. Hit up the source to check out the other proposed projects.
