After a foot survey, there is a notice on the SW corner of Marston Lane Bridge from Warwickshire County Council listing a 'Temporary Closure of Public Byway M450 Curdworth/ Wishaw'.
So, this confirms the highway_authority_ref=M450 is correct, although 'Public Byway M450' would prevent any confusion with motorway ref's..
The closure order prohibits all traffic except pedestrians until works end or 2016-08-06.
I have survey photographs available.
