At Lyon, on the River Rhone, a new bridge had been built in keeping with modernised traffic road development. It has an attractive aspect in smooth, light-coloured concrete and can accommodate several cras abreast. But, apart from appearance, there is the most important consideration, can it safely carry the tremendous weight of peak traffic - with all the various vibrations that can arise. To make sure, the engineers stage a weight test, using heavy lorries to provide the tonnage and the movement. Experts with theodolites, plumb lines and levels study the effects as the lorries move slowly over the bridge. But 'le pont De Lattre de Tassigny' comes out of the test with flying colours.
