We crave spontaneous urban encounters yet our current city model, based on large swaths of non-space for transit, lacks the public platform needed to satisfy our social nature. This infrastructure transforms the Los Angeles freeway network into a public space that re-connects the city with its inhabitants. Once the most vibrant part of the city, walls allowed for informal commerce that escaped city regulation. Hollenbeck Park, once an idyllic escape for neighbors to coalesce, was bisected by the I-5 and the I-10 in the 1960s. Reviving this freeway into a permeable membrane, returns the once spontaneous mediator condition to the present network.
