Roads on the black soils tend to crumble at the edges as the soft humus collapses and oxidises. This road is typical of fen roads, in needing frequent attention to deal with that. It is typical too, in that it rises and falls as it passes over the silt banks left amongst the peat by small to medium marine creeks from the Middle Bronze Age, 3 to 3½ thousand years ago. This was before the peat in the soil was laid down.
