Hi. I'll remove the short section across the line for now. Web searching suggests that the crossing has been "temporarily" closed since 2006 and was part of Network Rails proposed closures which faced objections (for example the Ramblers Association proposed a bridge at this location, Abbotts Crossing, rather than the proposed "unreasonable" diversion). The public enquiry  ended in February 2019 but I have seen no footpath extinguishment orders in the local paper since then for any paths in this area, and can't find anything more recent than the public enquiry to say which crossings have officially been permanently closed.
