A massive steel I-beam is hammered into the ground like a golf tee or a tent stake, holding up the trolley wires that have run up Market Street since just after the great earthquake in 1906. Before that, horsecars, steam trains and cable cars all took their turn on Market Street’s rails. The beam stands there because the Central Subway is under construction below and there are many moving pieces as workers rearrange everything to make way for the underground concourse.
Beyond the tangle of wires the shiny metal box that is the Apple Store, a reminder that many of the recent developments in city life have nothing to do with the construction of buildings or transport infrastructure but in the way we interact with them.
