This section of path is currently flooded (and signs notify that fact). Bexley PRW Team are aware and the Electricity company that own the field were originally going to resolve the issue, but then we all went into Lockdown.
Temporary measure is to walk across the field.
As an aside, the OS mapping indicates that the RoW turns up and over the hill! TBH that would make a pleasant alternative for the benefit of a viewpoint!

There is feedback from driver, which shows that he couldn't drive through this road. Is there any kind of obstacle, access ban, turn restriction, or something else? #mbx_uk_editing
