Bridge to infinity

Infinity Day has us visiting Perth, Australia, and the Elizabeth Quay Bridge. From this aerial view, the bridge closely resembles a tilted ∞, the common symbol for infinity first popularised in a 17th-century mathematical text. Infinity Day is an unofficial occasion marked by some on 8 August, because the number 8 resembles the infinity symbol, and the eighth day of the eighth month is an infinitely superior day to celebrate the infinite.

View this bridge from ground level and you’ll quickly realise that the graceful figure-of-8 seen from above is something altogether different when viewed from below. The architects behind this bridge designed it to dramatically link the Swan River with the city. The upper left and bottom right curves seen in this image are actually double arches that loop up and then under a 360ft (110m) pedestrian and bicycle path. This path offers striking views of Perth’s central business district and links the area with the newly developed Elizabeth Quay mixed-use development, featuring shops, cafés, apartments and bars. If you do ever have a chance to take a walk on this bridge, we recommend taking a moment to ponder the infinite, just like the mathematicians and philosophers of the 17th century did.
