After the Kensington Expressway had enveloped the Humboldt Parkway it continued north, cutting through Delaware Park, the centerpiece of Olmsted’s park system. The freeway divided into isolated pieces what had once been a single, cohesive park on the scale of Prospect Park in Brooklyn. The park became a series of sub-parks, separated by walls of high-speed traffic with very few means of crossing (aside from sprinting across the road). Large swaths of parkland were covered in asphalt and significant portions Hoyt Lake were filled in. The intersection of the park’s primary pedestrian promenades was replaced with a cloverleaf intersection. What was once the central hub of the park had become an impassable void, eating up dozens of acres of what had once been public parkland.
