text: Needs a proper on-the-ground survey.  I find it hard to believe that http://www.openstreetmap.org/way/177970308 doesn't join the A15 here, and that there is a footpath http://www.openstreetmap.org/way/153797488 that is entirely separate to the road and doesn't join it either.  I suspect what is actually on the ground is a sidewalk=left/right/both - but needs checking.
