America’s longest freeway capping parks

Below are freeway capping projects that incorporate park land or greenspace atop the deck that have taken place or which are proposed in the United States. They are listed by their known or approximate length (~) using Unfortunately, there are not as many of these projects as one would hope or expect given the many benefits derived from them.

As the name for the proposed project in downtown Atlanta hints (“The Stitch”), most, if not all of these projects are attempts to right a terrible wrong that took place during the peak freeway-building era in the United States (1945-1990). During this time period, freeways were carved through cities with little to no regard for the neighborhoods and communities destroyed, the people uprooted (mostly poor and minorities), nor the long-term consequences from noise and pollution.

While some freeway capping projects have been noteworthy and successful in revitalizing adjacent and nearby areas, some remain controversial. In El Paso for example, the freeway capping project is being tied to a widening to I-10, including the construction of more frontage roads and the removal of other surface street connections.

Fortunately, freeway capping projects like Freeway Park in Seattle, South Riverwalk Park in Trenton, and the Rose Kennedy Greenway in Boston have shown the positive (and successful) side of rebuilding connections. The primary purpose of building a park cap over a freeway should not be to create more wealth for the privileged, but should be to reconnect neighborhoods, build equity for inner-city residents, and partially right a terrible wrong from the 20th century. To do other wise only deepens the wound.

Whether built (or proposed) for the right reasons or the wrong ones, here’s the list. As always, any additions, corrections, or suggestions are most welcome. Peace!
