Blueprint America goes to three very different American cities — Denver, New York and Portland, and their surrounding suburbs — to look at each as a microcosm of the challenges and possibilities the country faces as citizens, local and federal officials, and planners struggle to manage a growing America with innovative transportation and sustainable land use policies.

With roads clogged and congested, gas prices uncertain, smog and pollution creating health problems like asthma, cities that once built infrastructure to serve only automobiles and trucks are now looking to innovative new forms of transportation systems — like trolleys, light rail, pedestrian walkways and bike paths.

Whether it is talking to residents pushing sustainable development in the Bronx, smart growth in Denver, or a journalist in Portland whose beat is bicycling, Blueprint America finds a common theme: America’s love affair with the car may be a thing of the past, and that may be the road to economic recovery.
