[1] It was built by the cycling charity Sustrans between 1979 and 1986, which leased a five-mile (8.0 km) stretch near Saltford, with the help of the then Avon County Council, and using volunteers turned it into its first cycleway.
The path follows the route of the Midland Railway Mangotsfield and Bath branch line, which was closed during the Beeching Axe of the 1960s in favour of the more direct former Great Western Railway between the cities, from Lawrence Hill in central Bristol to Newbridge in Bath.
It passes through the suburbs of Easton, Fishponds, and Staple Hill, then the villages of Mangotsfield, Warmley, Bitton and Saltford, before ending at Newbridge.
[3] From 1999 to July 2001 South Gloucestershire Council built a new section of the A4174 Avon ring road along part of the path.
While the work was being undertaken the path was diverted away from the old railway line and a new section was added around the ring road, increasing the length by 200 yards.
The new section includes two bridges, several tight corners, a hill (South Gloucestershire Council describes it as a 'barely perceptible gradient'), and two cattle grids.
The station platform at Warmley contains a cafe, serving refreshments seven days a week year-round, and includes public toilets.
[5] In January 2008, a plan was revealed by the West of England Partnership to turn sections of the path between Emersons Green and Bristol City Centre into a Guided Busway.
