GeoGraph - photograph every grid square

This is a telephoto shot from the bridge over the motorway carrying the road from Sutton Benger to Great Somerford. The marker at the lower left of the image is one of the 100 metre distance markers alongside the edge of all UK motorways. The one immediately west of this one i.e. behind the viewpoint, is situated just under the western face of the bridge so we can place this one fairly precisely at grid reference ST94857960. The temporary notice board in the fetching shade of turquoise is at ST94957963 as can be deduced from the presence next to it of the 100 metre marker (confirmed by GPS). That marker is thus approximately 50 metres west of the western gridline of the next square east, ST9579. The permanent sign board marking the proximity of the River Avon is at ST95027964, established by observation and GPS. The gridline between the square we are in and the next one east is indicated by the location of the silver car in the middle lane of the motorway.
