I think...
The hay thing derives from the times that materials required for the bridge maintenance would arrive on site by horse and cart. The easiest thing to sling over the side of the bridge, which was not required for the immediate works, was the fodder for the horse.
That makes sense, thanks!I think...

Yes, it's a lovely tradition and a very effective day-mark. Have seen it a few times in recent years. The tidal thames PLA bylaw says "When the headroom of an arch or span of a bridge is reduced from its usual limits but that arch or span is not closed to navigation, the person in control of the bridge must suspend from the centre of that arch or span by day a bundle of straw large enough to be conspicuous and by night a white light."
