"4.11. The steel road bridge across the creek dates from 1976 but is set onto older, more interesting, abutments of brick and stone. Hydraulic accumulators and a hand operated pump of 1878 still provide the means for lifting the bridge off its seatings, but the last vessel to pass through here was in 1993. The release of water through the sluices is still the all-important means of cleansing the navigational channel, but with the head of the creek steadily silting up the reducing volume of available water makes the flushing action progressively less effective. This crossing point, with its panoramic views up and down the creek, its sluice gates and its old brick and stone abutments, continues to be a place of special appeal."
