Wheeler didn’t hesitate to acknowledge that adding lanes never helps congestion, thanks to the principle of induced demand. Instead, what he emphasized about the project is its progressive window-dressing: its cap. A few blocks of the highway would be lowered below grade and planted with a bit of Chia fuzz, with a new bike-ped crossing on one of the sides. This is the grid “restoration” of which the mayor speaks—essentially, a minor diminishment of a roaring, stinking concrete channel that will roar and stink all the more with this added capacity.
Highway caps are an ever-more common feature of 21st century urban highway projects, and this project sounds a lot like some others we’ve heard of recently—namely, the Colorado DOT project that promises to triple I-70’s footprint through two of Denver’s last working-class neighborhoods and cover a small section with a park. The project has been mired in controversy for years, with lawsuits and pleas to the governor to halt it on environmental and social justice grounds.
Ironically, the 800 square-foot “cap park” proposed for the Denver boondoggle stemmed from early community advocates who pushed back against CDOT’s original plans to simply widen the existing elevated structure. The introduction of the cap a few years ago was heralded as a victory by some residents of the neighborhoods, which have been passed over for local investments for years. But the I-70 project, with its attractive grassy mask, has since been corralled into a suite of plans to redevelop huge swaths of the affected neighborhoods.
Now, the fear of displacement, underscored by the property-value increases that highway cap parks can bring, has driven many longtime Denverites to bitterly oppose the construction. “I just hope my kids will get to play there,” said one local mom who regretted ever advocating for the project, which a Denver public policy expert compared to “old-fashioned 1950s slum-clearance.”
This sounds like greenwashing. It can take many forms in trying to beautify or distract from uglier elements of the built environment. Does a few bushes in planters in the parking lot really transform the setting and allow a visitor to escape into nature? This is the subject of part of James Kunstler’s TED talk “The Tragedy of the Suburbs” – with roughly 8:00 minutes remaining – where he dissects such parking lot plantings. Even expanding the size of the nature area, such as park in these examples, may not be enough if the surrounding land use is even more sizable.
