Personal website of Martin Halford
Martin at Mas St Antoine near Avignon.
This is the first of two photographs of pontoon bailey bridges that I've scanned from negatives. The index suggests this is over a canal near Gennep in Holland
At first I thought this was the same location as the one above, but on further inspection this is not the same bridge.
The sign 'Derbyshire Bridge' might suggest a regiment.
This link to York and York II bridges over the Caen Canal and River Orne shows similar bridges and a Google search finds more, but not apparently the ones I found in my father's collection of photographs
