FREEWAY WITH A FRINGE ON TOP

The solution to the increasing need for freeways in congested metropolitan areas seems to be to put freeways below ground and use the air rights above as building sites. The article describes how such solutions are being implemented in Boston, Phoenix, Seattle (Washington), and in California (San Diego). Seattle forced a mile of an Interstate 90 extension into trenches that will be decked by parks. Boston is burying a mile of its congested Central Artery, and Phoenix, San Diego, Duluth and Hartford, Connecticut are building parks over sections of below-ground freeway. State highway departments in California and Washington have begun to market such sites. It is also noted, however, that air rights projects are difficult to design, and can create controversies of their own. Some highway departments object to constraints on their ability to expand freeway capacity.
