Building fire closes part of A6
A section of the A6 is expected to be closed for several hours while firefighters deal with a fire at a disused building in Bedford.
The fire began at the site behind Sainsbury's in Clapham Road just after 09:00 BST.
The A6 bypass heading north was closed, with diversions in place.
Traffic heading south into Bedford was very slow, with the dual carriageway reduced to one lane. Drivers were being asked to avoid the area if possible.
A nearby petrol station was closed as a precaution.
