The article you linked was talking about: > The metal spikes, part of a trend called "hostile architecture," appeared recently outside of an office building in Manchester, England, that's managed by commercial property agent GVA, according to The Guardian. The original wikipedia article uses the following examples: > - The Seattle Department of Transportation installed bicycle racks to prevent the homeless from camping.[14] > - A gas station in New Kensington, Pennsylvania installed blue lighting in their bathrooms that make it hard for drug users to find their veins.[15][16] > - Anti-homeless spikes on London's Curtain Road to prevent homeless people from sleeping there.[17] The further examples in the wikipedia article are clearly not otherwise unused overpasses.
