Drivers are being asked to avoid the Hatfield Peverel area of Essex this evening (21 May) after a bridge over the A12 was damaged during a crash.
The southbound carriageway is closed after a digger that was being carried by a lorry hit the bridge by the Wellington Pub at about 5pm. No-one was injured.
There are long delays towards London. Police say it could take some hours to remove the digger from the road.
The bridge at junction 20B has also been closed for safety reasons.
