In some parts of the country there are stretches of road that can be widened without material defacement of the landscape, but they are few. Ancient landmarks hamper progress in most places. Old bridges, for example, are altogether unsuited to heavy and fast motor-traffic. Often built askew with the line of a main road, they are nearly always very steep, very narrow, and, though often sturdy in appearance, are incapable of bearing the weight of a heavy lorry and trailer moving with the speed of a railway train. Here again is a problem requiring solution. Some people would attempt to adapt the old bridge to modern needs, others prefer an entirely new structure placed parallel with the old one, and, of course, the third alternative is complete demolition. The first method is generally impossible, and there is much to be said for a frankly modern design in reinforced concrete, provided that it does not stand in too close proximity to the ancient monument that it supersedes. Another familiar rural feature that must perforce give way to the insistent needs of the motorist is the ford or “watersplash.” Much as we may regret its disappearance, it has to go. But most difficult of all is the question of dealing with the narrow High Street of a town or village through which a main artery passes. Occasionally the jerry-builder has anticipated us here, and has erected some terrible Victorian nightmare of a shop right up to the old building-line of the historical cottages that he has demolished. In such a case the children of the Petrol Age may be able to expiate the sins of their fathers by pulling down that shop. But more often there is a building of real merit standing at the very bottleneck through which the procession of traffic has to squeeze its way, such as the old church at Barnet or the Whitgift Hospital at Croydon; and then we are in a quandary, impressed on the one hand by the legitimate needs of our time, deterred on the other hand by an almost religious sense of the sanctity of the past. Sometimes the obstacle is a mere cottage, a barn, a pump, a stone cross, or a quaint structure such as blocks Hampstead Lane near the Spaniard’s Tavern, yet even these must be treated with respect. The “by-pass” road, as suggested in the next chapter, is sometimes the best solution, but is not practicable everywhere. And lastly, there are the trees. As I write these lines I can hear the crashes of falling elms and yews that I have known since childhood. A snorting tractor is pulling them down bodily with a steel hawser, so that the grass-lined lane that runs near my home may be widened for the growing needs of what was once a pretty village.
