A shared-use path typically has a surface that is asphalt, concrete or firmly packed crushed aggregate.
[4] In the UK, cyclists are legally permitted to cycle on bridleways (paths open to horse riders), but not on public footpaths.
[10] The UK Department for Transport advises local authorities that cyclists and pedestrians should not be expected to share space on or alongside city streets.
[4] Sustrans gives advice for cyclists, walkers and runners using shared-use paths on the National Cycle Network.
The network consists of over 200 miles (320 km) of shared-use paths that avoid the city's busy and fast grid roads (which run between neighbourhoods rather than through them).
[12] In the US, the 1999 AASHTO Guide for the Development of Bicycle Facilities defines a shared-use path as being physically separated from motor vehicular traffic with an open space or barrier.
