Greystone Bridge was built under an indulgence of 40 days granted to all penitents by Bishop Lacy on 27th December 1439. It's the furthest upstream of three ancient crossing points on the River Tamar and carries traffic using the roads between Launceston in Cornwall and Tavistock in Devon.
The other two ancient crossings are those at Horsebridge and Gunnislake. It is likely that Greystone Bridge and Horse Bridge were the work of the same builder. Both are constructed of local stone with freestone dressings. The patron of these bridges may have been one of the Abbots of Tavistock, who owned large estates between the two.
Greystone Bridge has six semicircular arches of 7m span and two 4.3m flood arches. The road width is only 3m but the cutwaters, which project from the piers into the river flow, extend 8.2m up from the river bed to parapet level, providing safe havens for pedestrians.
In recent years, long vehicles have caused repeated parapet damage. Remedial work was carried out in November 2007, and included the widening the corner of the bridge approach at the Cornwall end and replacement of the traffic signals.
Greystone Bridge is a Grade I listed structure and a Scheduled Ancient Monument.
