Note 88 — Chapter VII · RAILWAY BRIDGES AND VIADUCTS.

Mr. Brunel, by taking care in his timber structures to distribute the load uniformly, was frequently able to dispense with costly foundations. On one occasion a timber viaduct 30 feet high was placed upon a broad platform resting on an old embankment upwards of 50 feet in height. A similar arrangement was adopted by him in some cases on slips in embankments which it would have been uncertain and expensive to make up with earthwork.
