Cycle path along A5 from Heyford Lane,Nether Heyford junction to corn hill, Bugbrooke junction is in places impassable

Vegetation along cycle path is overgrown along sections meaning you cannot cycle along the path and can cut your hands, arms, legs and faces on brambles etc.. I am complaining about the path that runs from the Narrowboat Public House to The junction of Corn Hill. In a couple of places you have to get on the A5 road as the vegetation has completely covered the path, which is extremely dangerous.
