The A47 is closed in both directions after a lorry crashed and overturned close to the Walton Highway roundabout between King’s Lynn and Wisbech.
Norfolk Police were called to the scene around 6.30am, and expect the road to be closed for several hours while recovery is underway.
A spokesman said there had been a fuel spillage onto the roundabout and debris from the lorry shedding its load.
Diversions are in place down the B198.
