In the middle ages the roads were exceedingly bad, and even in the seventeenth century they were far from satisfactory. Pepys mentions, in his Diary, June 16th, 1668, that he lost his way driving from Newbury to Reading. This, it will be observed, was in the summer, and one would think on a well-known road. In the eighteenth century the roads were gradually improved, and towards the end of the century began to be kept in good order for the coaches, which were also rapidly improving. In the early part of the nineteenth century two mail coach routes ran through Berkshire. The road from London to Gloucester entered Berkshire at Maidenhead and left the county at Henley. After passing through Oxford it again entered Berkshire, and ran by Cumnor and Fyfield to Faringdon. From that place it ran by Buscot Park and crossed the river Isis at St John's Bridge near Lechlade. The London and Bath mail route ran through the county by Maidenhead, Reading, Newbury, and Hungerford. Besides these mail-coach routes there were several roads in the county which came under the head of "turnpike roads." The term turnpike road means a road having toll-gates or bars on it. The toll-gates were first constructed about the middle of the eighteenth century, and were called turns, and the turnpike road was one upon which those who refused to pay toll could be turned back. Turnpike roads are now practically extinct and a new species of highway called main roads has taken their place. The cost of repair is borne partly by the county and partly by the Local Highway Authority. Canals and Rivers. Canals have to a large extent been superseded by railways in these days. It is, however, possible that the advent of cheap motor traction may cause them to revive. The Kennet and Avon Canal runs from Newbury, and entering Wiltshire near Hungerford furnishes a waterway from the Thames to the Severn. The navigation of the river Thames is improved by a number of weirs and locks, most of which have been re-made in recent times, and if more useful they are much less picturesque than in former days. The level of the river at Hambleden weir is just about 100 feet above the sea. The river Kennet is also provided with a series of weirs and locks. A canal which ran from Wantage to Abingdon is now disused. The bridges over the rivers are for the most part modern, but many of them replace older structures, indeed most of the crossing-places are very old. The bridge at Abingdon was originally built in the fifteenth century, and was under the charge of the Guild of the Holy Cross, and Maidenhead Bridge was the property of a corporation from early days.
