AB and CD should be perfect gradients, coinciding at their point of intersection-the carriageway to have a camber of 1 in 36 at A and B, which is to be reduced by raising the line of channels so that when the line CD is reached there will be no camber; this will give a suitable "round" to the crossings at the ends of the 36-foot road, and the water from the carriageway will be thrown toward the four corners.
