The bench mark is to be found on the east face of the bridge's west parapet. For a view of the bridge http://www.geograph.org.uk/photo/2052645 and for more information on the cut mark http://www.bench-marks.org.uk/bm35444 A bench mark is an Ordnance Survey arrowhead sign found on walls, bridges, churches and specially erected triangulation pillars where the altitude above sea-level has been accurately measured by surveyors. The arrowhead points to a horizontal line above it which marks the exact altitude. With rivets and pivots there is no datum (horizontal line) cut, the pointed-to horizontal surface defining the datum height.
