' There are two skew bridges 'cutting' through this series of arches. The one at the eastern end (left) is a plate girder bridge while in the middle there is a brick arch. The arches of the viaduct are built at right angles to the tracks above. It always rather surprises me that the railway built so many relatively complicated and expensive skew bridges to accommodate roads on the same alignment as before the railway was constructed. It must have been cheaper to do this than deal with the legal and land purchase costs to have the road moved to go through an arch at right angles to the railway. I suspect a much greater proportion of modern motorway bridges are on the 'square' with the approach roads moved to a new alignment. '
