Decking over expressways is not anything new, but since Boston's BIG DIG it seems cities are now looking at this as a real viable option to reconnect spaces that have been cut off from each other because of the creation of the freeway running through the cities.
Cities are removing the concrete barriers that freeways form through their downtowns — not by tearing them down but by shrouding them in greenery and turning them into parks and pedestrian-friendly developments.
Transportation departments are not opposed as long as the plans don't reduce highway capacity. In most cases, traffic is rerouted.
"It's the coming together of people wanting green space and realizing that highways are a negative to the city," says Peter Harnik, director of the Trust for Public Land's Center for City Park Excellence. "Covering them with green space gives you a wonderful place to live and work."
