Ancient trackway in the context of "Appian Way"

A greenway is usually a shared-use path along a strip of undeveloped land, in an urban or rural area, set aside for recreational use or environmental protection. Greenways are frequently created out of disused railways, canal towpaths, utility company rights of way, or derelict industrial land. Greenways can also be linear parks, and can serve as wildlife corridors. The path's surface may be paved and often serves multiple users: walkers, runners, bicyclists, skaters and hikers. A characteristic of greenways, as defined by the European Greenways Association, is "ease of passage": that is that they have "either low or zero gradient", so that they can be used by all "types of users, including mobility impaired people".

In Southern England, the term also refers to ancient trackways or green lanes, especially those found on chalk downlands, like the Ridgeway.

The Sweet Track is an ancient trackway, or causeway, in the Somerset Levels, England, named after its finder, Ray Sweet. It was built in 3807 BC (determined using dendrochronology – tree-ring dating) and is the second-oldest timber trackway discovered in the British Isles, dating to the Neolithic. The Sweet Track was predominantly built along the course of an earlier structure, the Post Track.

The track extended across the now largely drained marsh between what was then an island at Westhay and a ridge of high ground at Shapwick, a distance close to 1,800 metres (5,900 ft) or around 1.1 mi. The track is one of a network that once crossed the Somerset Levels. Various artifacts and prehistoric finds, including a jadeitite ceremonial axe head, have been found in the peat bogs along its length.

The Ridgeway is a ridgeway or ancient trackway described as Britain's oldest road. The section clearly identified as an ancient trackway extends from Wiltshire along the chalk ridge of the Berkshire Downs to the River Thames at the Goring Gap, part of the Icknield Way which ran, not always on the ridge, from Salisbury Plain to East Anglia. The route was adapted and extended as a National Trail, created in 1972. The Ridgeway National Trail follows the ancient Ridgeway from Overton Hill, near Avebury, to Streatley, then follows footpaths and parts of the ancient Icknield Way through the Chiltern Hills to Ivinghoe Beacon in Buckinghamshire. The National Trail is 87 miles (140 km) long.
