This article is about the bridge in Caithness. For the bridge on the Devon/Cornwall border, see Greystone Bridge.
Achingale Bridge, alternatively Watten Bridge or Greystones Bridge, crosses a small tributary to the Wick River immediately east of Watten on the A882. It was built by Thomas Telford under his commission for Highland roads and bridges, and completed in 1819. The bridge is a 3 span stone arch bridge, with the centre arch marginally larger than the two side arches. There is still a rise of the road over the bridge, however, and the distance between the string course and top of the parapets appears higher than is normal on a Telford Bridge. Despite being a late example of Telfords Bridges in the Highlands, it remains an austere design built of local stone, with small triangular cutwaters flanking the piers in the river bed. The bridge was widened on the north side in 1933 with the original parapet reinstated.
