The politics of public space at São Paulo's Parque Minhocão.

São Paulo's Minhocão (Big Worm) is a 3.5 km elevated expressway that cuts across a dense part of the central city. Opened in 1971, it was controversial from the start, and widely held responsible for the decline of the city's historic centre in the 1970s and 1980s. However, it has been gradually tamed over the years, first closed to traffic at night, and then at weekends and on holidays, becoming an impromptu park, the Parque Minhocão, which has had official status since 2014. Those informal closures have been accompanied by numerous architectural schemes over the years to make the Minhocão a permanent park on the lines of New York's High Line. The Parque Minhocão in its present condition represents a stand-off between various interest groups, all of whom have claims on it as public space. The paper explores the history of the Parque Minhocão since 1969 through different forms of visualisation, arguing that its present condition, however imperfect, keeps multiple and contradictory interests in balance.
