Bridges: turnover
Back in the days when narrowboats were towed by horses, the canal network supported essential architecture which is no longer in working use today.
Perhaps the most common example of this is turnover bridges.
At certain points it is necessary for the towpath to move from one side of the canal to the other. At these points, there was a danger of the horse’s towline getting tangled as the horse completed the manoeuvre across the canal. Early canal engineers soon came up with the solution of turnover, or snake, bridges.
The smooth lines of these bridges make them among the most attractive waterway structures.
