Most every time I cross the bridge, I remember one of the first times I walked over it, back in the late 1990s or early 2000s, when some wag—possibly even Banksy, who knows?—had painted a sign on the footway about here: a rectangle of yellow caution stripes containing the words "WARNING. CONCEALED TRAPDOORS IN OPERATION".
