Equestrians are able to enjoy on average only 22% of the PRoW network. Any enhancements to a bridleway should consider the needs of all users, for example using an appropriate surface materials. Please see British Horse Society guidance on surfaces https://www.bhs.org.uk/advice-and-information/free-leaflets-and-advice
Active travel includes equestrians as vulnerable road users (Jesse Norman MP, 2018). Improvements to the connectivity of cycle and pedestrian routes should include equestrians where it could avoid horse riders being sandwiched between fast moving motorised traffic and fast moving cyclists, to improve safety.

2iv is written in a way that suggests the bridleway will be a footpath.
3v does not include equestrian access.
