To mitigate a steep ascent, a central carriage-way, 200 yds, long, is cut along the main street to a depth of 15 ft., the opposite terraces being connected by a bridge.
in width, including the raised footpaths on each side, which occupy a considerable part of the space, so that the carriage-way could only have admitted of the passage of one vehicle at a time.
They are also in all cases bordered by raised footways on both sides, paved in a similar manner; and for the convenience of foot-passengers, which was evidently a more important consideration than the obstacle which the arrangement presented to the passage of vehicles, which indeed were probably only allowed for goods traffic, these are connected from place to place by stepping-stones raised above the level of the carriage-way.
Therefore every highway - whether carriage-way, driftway, bridleway or footway - which can be shown to have been in use before 1836, is presumably repairable by the inhabitants at large, the only exceptions being such highways as are repairable by private persons or corporate bodies ratione clausurae, ratione tenurae, or by prescription.
Its height, subject to water-pressure, is about 134 ft., and a carriage-way is carried on arches at an elevation of about 18 ft.
