In what part of the kingdom have you been employed, and what observations have occurred to you upon this subject?—The whole of the works executed under the Commercial Road, the East India Road, the Barking Road, and the Tilbury Road Acts, have been under my direction, as well as the roads made under the Bridge and Dock Companies, for which I have been engineer. The Commercial Road, which is between the West India Docks and London is referred to in the report of a former Committee on highways, as particularly well fitted for heavy traffic; that road is seventy feet wide, and is divided into two footways, each ten feet, and a carriage road fifty feet wide, of which twenty feet in the middle is paved with granite. I have a section of the form of this road (No. 1, in the annexed plan.) The East India Dock branch of the Commercial Road is also seventy feet wide, ten feet of which is paved with granite. I have prepared also a section of that road (No. 2, in the plan.) The traffic upon the Commercial Road, both up and down, is very great, and necessarily required a width of paving sufficient for two carriages to pass upon it. I am quite sure that the expense of this road would have been very much greater, probably much more than doubled if it had not been paved, and that the carriage of goods would also here been much more expensive; indeed it would have been next to impossible to have carried the present loads upon a gravelled road. The road has been paved for about sixteen years, and the expense of supporting it has been small, although the stage-coaches generally, as well as almost all the carts and waggons, go upon it; while the expense of the gravelled part has been comparatively great. During the thirteen years that the East India Dock branch has been paved, the paving has not cost 20_l._ in repairs, although the waggons, each weighing about five tons, with the whole of the East India produce, which is brought from the docks by land, have passed all that time in one track upon it, and a great deal of heavy country traffic for the last eight years, when a communication was formed with the county of Essex. The advantage of paving part of a road where the traffic is great, and the materials of making roads bad or expensive, is not confined to improving the conveyance for heavy goods and reducing the horses’ labour; but as the paving is always preferred for heavy carriages, the sides of a road are left for light carriages, and are kept in much better repair than otherwise they could possibly be. It is not, I am sure, overstating the advantage of the paving, but rather otherwise, to say, that taking the year through, two horses will do more work, with the same labour to themselves, upon a paved road than three upon a good gravelled road, if the traffic upon the gravelled road is at all considerable, and if the effect of this, in point of expense, is brought into figures, the saving of the expense of
