Through a combination of regulation and public policy, the city has vastly reduced the number of cars on its streets, introducing bike lanes and public green spaces in the place of around 50,000 parking spaces. This issue is dedicated to roads and the architectures that support them. Cities around the world are reckoning with 20th-century car-oriented urban planning, as epitomised by Robert Moses’s New York (p36). Existing roads are increasingly repurposed for broader uses, prioritising pedestrians, cyclists and other forms of movement. São Paulo’s Minhocão has been gradually reclaimed by residents, and the restoration of a historical promenade in Reus is inclusive for all. Meanwhile, OMA’s new bridge in Bordeaux is designed to host public events – as well as six lanes of motorised traffic. Elsewhere, automobile infrastructure continues to expand; in Bahrain, four new car parks stand largely empty, and a roadside service station in Colombia is yet to be occupied. Roads promise prosperity and progress, often with expansionist ambitions; as Nadi Abusaada writes, ‘The road is both the myth and mechanism of the colonial frontier’.  Electric vehicles are now heralded as the future of transport, but as Nelo Magalhães writes in this issue’s keynote, ‘EVs do nothing to change the mass of roads or the issue of their maintenance’. The shift needed is more radical and wide‑reaching.  1522: Roads cover (above)Highway #5, Los Angeles, California, USA (2009) is part of Edward Burtynsky: The Great Acceleration, an exhibition on view at the International Center of Photography in New York City until 28 September.
