This guy has a quick fix for the crisis on Brooklyn's busiest highway—and few are paying attention
New York City's Brooklyn-Queens Expressway is falling apart. Built between 1946 and 1964, the urban highway runs 12.1 miles through the heart of the two boroughs to connect on either end with the interstate highway system—a relic of midcentury car-oriented infrastructure, and a prime example of the dwindling lifespan of roads built during that time.
The degradation is most visible—and most pressing—in a section running alongside Brooklyn Heights known as the triple cantilever. This 0.4-mile section, completed in 1954, is unique among U.S. highways in that it juts out from the side of a hill and stacks the two directions of traffic on balcony-like decks, one slightly overhanging the other. A third level holds a well-loved park, the Brooklyn Heights Promenade.
This unusual layer cake of a freeway was a marvel of engineering in its day, though not without controversy. Masterminded by Robert Moses, the city's all-powerful, often ruthless city planner for more than four decades, the roadway bisects working-class and immigrant neighborhoods that grapple with the health and environmental fallout to this day.
Like the reputation of the man who built it, the triple cantilever has aged poorly. Its narrow width, (33.5 feet for the roadway in either direction) has made all but the most basic maintenance incredibly difficult, and its 71-year-old structure is constantly battered by the ever heavier automobiles and trucks. Designed to accommodate around 47,000 vehicles per day, it now carries more than three times that amount. Deteriorating deck joints and failing steel-reinforced concrete have led many to worry the triple cantilever is on the verge of collapse. An expert panel warned in 2020 that the triple cantilever could be unusable by 2026.
