I have been studying the remains of a wooden railway bridge which was built
across the entrance to Portland Harbour, whilst it was being constructed in
the 1850s. In an undated plan of the construction work (possibly from the
Illustrated London News) the railway bridge is described as being carried
on ‘Gawntree Staging’.
An internet search has drawn a blank, so does anyone know what Gawntree
Staging was? Drawings of the bridge, as well as the remains on the harbour
floor, suggest it was carried on pairs of wooden piles with lighter,
possibly metal, cross bracing.
