Wades Causeway, known as Wheedale Roman Road

Wade's Causeway is a sinuous, linear monument in the North York Moors national park in North Yorkshire, England. The name may refer to either scheduled ancient monument number 1004876—a length of stone course just over 1 mile (1.6 km) long on Wheeldale Moor, or to a postulated extension of this structure, incorporating ancient monuments numbers 1004108 and 1004104 extending to the north and south for up to 25 miles (40 km). The visible course on Wheeldale Moor consists of an embankment of soil, peat, gravel and loose pebbles 0.7 metres (2.3 ft) in height and 4 to 7 metres (13 to 23 ft) in width. The gently cambered embankment is capped with unmortared and loosely abutted flagstones. Its original form is uncertain since it has been subjected to weathering and human damage. (From Wikipedia)
