A47 closed at Saddlebow Interchange at King's Lynn for bridge repairs
Drivers can expect delays on the A47 south of King's Lynn this weekend.
The road will be closed at the Saddlebow Interchange while bridge repairs take place. Vehicles will be diverted up and over the slip roads.
A large crane is replacing bridge beams which were damaged after being struck by a digger on the back of a lorry.
The work is expected to take until April to complete. The A47 beneath the bridges is expected to re-open at 6am on Monday.
