text: Eyeballs today: there are no physical width restrictions. The signs on the A506 roundabout indicating a restriction have been roughly sprayed over with grey paint at the exit to the rbt, but they're still there on the approach to the rbt southbound. 
  
  Possibly this width restriction has been removed? I always thought the point was to have heavy traffic use the modern bridge at Barnwell rather than the centuries-old North Bridge. 
  
  Anyone local know the score?
