There are documentary references to the building of "A Bridge on the River Stour adjacent to the White Mill" in the year 1175. Although the bridge you'll see today is probably a sixteenth century structure (somewhat hacked around by the Victorians). It is known, from an investigation of the foundations a few years ago, that the bridge stands on timber pilings which have themselves been carbon dated to the twelfth century. This is alleged to be the oldest bridge site in Dorset.
