Big spaces, big cities, big freeways. This equation has held ground since the boom of major road developments in the 1970s. But a Dallas group lead by urban designer Patrick Kennedy is fighting that conception. He and his initiative, A New Dallas, are pushing a proposal that has been steadily gaining support since it began two years ago. Interstate 345 is an eight lane, 1.4 mile stretch of elevated highway that serves roughly 200,000 commuters weekly. Kennedy wishes to demolish the structure completely, replacing it with a major surface street, four new parks, $4 billion in new private investment, and homes for 25,000 Dallas residents.
