Park Over the Highway in St. Louis, MO – Source: https://inhabitat.com/missouri-is-building-a-lush-public-park-over-the-interstate-70-freeway/park-over-the-highway-kci-1/
In recent years there has been an effort in some cities to mend some of the wounds of Interstate Highway era gashes that were savagely cut through American cities. A method for healing these scars has been to cap the freeway, essentially by putting it underground.

Below is a list of those cities where segments of freeways were originally capped at time of construction (shown in bold/parenthesis) or which have been and/or are being proposed to do so now in an attempt to heal the past scars. While a number of uses are identified in the list as being built over the freeways, the most popular appear to be the ones which incorporate a park-like setting. Unfortunately, most of the projects listed are not designed to heal devastated minority neighborhoods that took the brunt of Interstate Highway Injustice. The only freeway capping projects that appear to have this goal at least partly in mind are:
- Boston – Rose F. Kennedy Greenway
- Dallas – I-35E through the Oak Cliff neighborhood
- Denver – I-70 through the Elyria-Swansea neighborhood
- East Los Angeles – CA 60 through Belvedere Park
- Pittsburgh – Cap Park over I-579 at the Hill District
- Seattle – Freeway Park over I-5
- St. Louis – I-44 along the riverfront
- St. Paul – I-94 though the Rondo neighborhood
Sadly, there are so many more minority neighborhoods that could use a freeway capping project to help heal the scars of the Interstate Highway Injustice era of the 1950s through the 1980s.
While most highway capping projects have received positive responses, in at least one case, Denver, the proposal has met with stiff resistance because it is feared the project will harm the adjacent minority neighborhoods even more than the original damage had done. Other concerns have been raised in both Dallas and St. Paul that such a capping project could spur gentrification of the minority neighborhood, rising rents which could force our low-income residents, and the potential for developers to move in and buy up properties for redevelopment.

While this author sees a number of benefits of such freeway capping projects, one cannot help but wonder what the longer term result could be, particularly in those disconnected and divided neighborhoods that just happen to be situated in/near what is now a desirable or trendy location. If the freeway capping project is meant to create a public park, then the benefits will likely apply to all regardless of social, economic, or demographic status. On the other hand, if the freeway capping project is simply meant to be a new way to create more development potential and profits for corporations and the wealthy, then I would be just as wary as those who currently live there. The proof is in the pudding, as they say. Peace.
